CSF is a clear, colorless fluid that surrounds the brain and spinal cord, providing protection and nutrients. It is continuously produced and reabsorbed, maintaining a constant volume. The correct answer of 140 mL suggests that this is the average daily amount of CSF present in the nervous system.

Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration. In the context of transporting substances across a cell membrane, diffusion is a passive process that does not require energy. It allows small, nonpolar molecules such as oxygen and carbon dioxide to move freely across the lipid bilayer of the cell membrane. Therefore, diffusion is the correct answer for the given question.

A ganglion is a term that describes an accumulation of nerve cell bodies in the peripheral nervous system (PNS). This is different from a nucleus, which refers to a cluster of nerve cell bodies in the central nervous system (CNS). Gray matter refers to regions of the CNS that primarily consist of nerve cell bodies and synapses, while a peripheral nerve is a bundle of nerve fibers that connect the CNS to the rest of the body. Therefore, the correct term for an accumulation of nerve cell bodies in the PNS is ganglion.

K+ is the most abundant intracellular cation because it plays a crucial role in many cellular processes. It helps maintain the cell's electrical potential, regulates osmotic balance, and is involved in the transmission of nerve impulses. Additionally, K+ is required for proper muscle function and protein synthesis. While other ions like PO43-, HCO3-, and Cl- are also present in cells, K+ is the most abundant intracellular cation.

When erythrocytes are placed in a hypotonic solution, the solution has a lower solute concentration compared to the inside of the cells. As a result, water will move into the cells through osmosis, causing them to swell. This is because the water moves from an area of lower solute concentration (the hypotonic solution) to an area of higher solute concentration (inside the cells).

Passive transport refers to the movement of substances across a cell membrane without the use of ATP (adenosine triphosphate), which is the energy currency of the cell. Permeability refers to the ability of a substance to pass through a membrane. In this context, the correct answer states that passive transport occurs by permeability without the use of ATP. This means that substances can pass through the cell membrane freely based on their concentration gradient, without the need for energy expenditure.

Aldosterone is not involved in the metabolism of glucose. It is a hormone produced by the adrenal glands that helps regulate the balance of salt and water in the body. It plays a role in controlling blood pressure and electrolyte levels, but it does not directly affect glucose metabolism. Insulin and glucagon are the primary hormones involved in regulating blood sugar levels, while cortisone is a steroid hormone that has various effects on metabolism, inflammation, and immune response.

Exocytose is the process by which cells release substances from their cytoplasm into the extracellular space. It involves the fusion of vesicles containing the substances with the cell membrane, followed by the release of the vesicle contents outside the cell. This process is commonly used for the secretion of hormones, neurotransmitters, and other molecules. It is different from diffusion, osmosis, and filtration, which are passive processes that involve the movement of substances across a membrane without the need for vesicles or active transport.

Neurotransmitter receptors are located on the postsynaptic membrane. This is where the neurotransmitters bind and transmit signals from one neuron to another. The postsynaptic membrane is located on the receiving end of the synapse, while the presynaptic membrane is on the transmitting end. Nodes of Ranvier are gaps in the myelin sheath of a neuron, and synaptic vesicle membranes are involved in the release of neurotransmitters. However, it is on the postsynaptic membrane where the neurotransmitter receptors are specifically located.

Sodium is relatively high in extracellular fluids because it plays a crucial role in maintaining fluid balance and regulating blood pressure. It is the most abundant cation in extracellular fluids and helps to control osmotic pressure, which affects the movement of water in and out of cells. Sodium is also involved in nerve impulse transmission and muscle contraction.

Calcitonin and PTH (parathyroid hormone) are the hormones that control the regulation of calcium in the body. Calcitonin helps to decrease blood calcium levels by inhibiting bone breakdown and increasing calcium excretion by the kidneys. On the other hand, PTH increases blood calcium levels by stimulating bone breakdown, increasing calcium absorption from the intestines, and decreasing calcium excretion by the kidneys. Together, these hormones work in a delicate balance to maintain the appropriate levels of calcium in the body.

Radiation is known to cause damage to cells and DNA, leading to various health issues. The fact that 60% of the answer options state that radiation causes the cancellation of targets suggests that a significant majority of the options support this statement.

This is because polymorphonuclear leukocytes, or polynucléaires, are a type of white blood cell that plays a crucial role in the immune response against infections. They are responsible for engulfing and destroying foreign pathogens, such as bacteria and fungi, through a process called phagocytosis. Therefore, the presence of polynucléaires in the body is indicative of an active and effective immune response against infections.

The correct answer is A et B. This means that the AB blood group has both agglutinogens A and B present on the surface of its red blood cells. Agglutinogens are antigens that determine the blood type and can cause agglutination (clumping) of the blood if incompatible blood types are mixed. In the case of AB blood group, both A and B antigens are present, making it the universal recipient as it can receive blood from any blood type without agglutination.

The correct answer is α (anti A). This means that the blood group type B has agglutinogens that are anti-A, meaning they can agglutinate with the A antigen.

The correct answer is "cloison inter ventriculaire". This is because the question is asking about the location of the "faisceau de His" within the "système nerveux intrinsèque" (intrinsic nervous system). The "faisceau de His" is a bundle of specialized conducting cells that transmit electrical signals in the heart, and it is located in the "cloison inter ventriculaire" (interventricular septum), which separates the two ventricles of the heart.

Microglia are the correct answer because they are the phagocytic cells in the central nervous system (CNS). These cells are responsible for engulfing and removing cellular debris, pathogens, and dead cells through phagocytosis. Microglia also play a role in regulating immune responses and maintaining homeostasis in the CNS. Unlike other glial cells such as astrocytes, oligodendrocytes, and ependymal cells, microglia are specialized immune cells derived from myeloid progenitors.

The sensory speech area in the brain is called the Wernicke area. This area is responsible for the comprehension and understanding of spoken language. Damage to the Wernicke area can result in a condition known as Wernicke's aphasia, where individuals have difficulty understanding and producing coherent speech. The Broca area, on the other hand, is responsible for the production of speech, while the auditory area processes auditory information and the visual area processes visual information.

Excessive vomiting can lead to dehydration. Vomiting causes the body to lose fluids, including water and electrolytes, which are necessary for proper bodily functions. When these fluids are not replaced adequately, dehydration can occur. Dehydration can cause symptoms such as thirst, dry mouth, fatigue, dizziness, and decreased urine output. If left untreated, severe dehydration can be life-threatening. Therefore, it is important to replenish fluids and electrolytes lost due to vomiting to prevent dehydration.

Cortisol is released by the adrenal cortex. It is a steroid hormone that plays a crucial role in regulating various bodily functions, including metabolism, immune response, and stress response. It helps to maintain blood pressure, regulate blood sugar levels, and reduce inflammation. Cortisol is often referred to as the "stress hormone" because it is released in response to stress and helps the body cope with it.

Parathormone is the correct answer because it is the hormone that regulates calcium levels in the blood. Hypocalcemia refers to low levels of calcium in the blood, and parathormone helps to increase calcium levels by stimulating the release of calcium from the bones and increasing the reabsorption of calcium in the kidneys. This hormone also stimulates the production of active vitamin D, which helps to increase calcium absorption in the intestines. Therefore, parathormone plays a crucial role in maintaining calcium homeostasis in the body.

Glycogen is a polysaccharide that serves as a form of energy storage in animals. It is made up of glucose molecules that are linked together in a branched structure. When blood sugar levels drop, glucagon is released by the pancreas to stimulate the breakdown of glycogen into glucose, which can then be used as a source of energy by the body. Therefore, glycogen is the correct answer as it is directly related to glucagon's role in regulating blood sugar levels.

The correct answer is "Le ARNm". In genetics, the mRNA (messenger RNA) is responsible for carrying the genetic information from the DNA to the ribosomes, where it is used as a template for protein synthesis. The mRNA molecule is transcribed from the DNA and contains the instructions for the sequence of amino acids in a protein. Therefore, the mRNA plays a crucial role in the genetic code by transmitting the information necessary for protein production.

The diffusion of Ca2+ ions into the synaptic knob triggers the release of neurotransmitter. This is because the influx of Ca2+ ions into the synaptic knob is an essential step in the process of neurotransmitter release. When an action potential reaches the synaptic knob, it causes voltage-gated Ca2+ channels to open, allowing Ca2+ ions to enter the knob. The increase in Ca2+ concentration inside the knob then triggers the fusion of neurotransmitter-containing vesicles with the presynaptic membrane, leading to the release of neurotransmitter into the synaptic cleft.

The cerebrospinal fluid is produced by the capillaries of the choroid plexus. The choroid plexus is a network of blood vessels located in the ventricles of the brain. It is responsible for producing and regulating the cerebrospinal fluid, which provides nutrients and protection to the brain and spinal cord. The capillaries of the choroid plexus filter blood plasma and secrete cerebrospinal fluid into the ventricles, where it circulates and is eventually absorbed back into the bloodstream.

All of the given options are physiological responses that can occur together effectively except for digestion. Digestion is a parasympathetic response, which means it is associated with the "rest and digest" state of the body. On the other hand, the other options - increase heart rate, sweating, and pupil dilation - are sympathetic responses that are associated with the "fight or flight" response. Therefore, digestion is the odd one out as it is not typically associated with the other three responses.

Acetylcholine is the correct answer because it is the primary neurotransmitter released by the parasympathetic nervous system. It acts on autonomic targets, including smooth muscles, cardiac muscles, and glands, to promote rest and digestion. Adenosine is not a primary neurotransmitter of the parasympathetic system, and norepinephrine and dopamine are neurotransmitters of the sympathetic nervous system.

The correct answer is B because the question is asking about the agglutinogen present in blood type B. Blood type B has the B agglutinogen on its red blood cells, which means it can produce antibodies against blood type A. This is why blood type B can safely receive blood from type B and type O individuals, but not from type A or type AB individuals.

Insulin is the correct answer because hypoglycemia is a condition characterized by low blood sugar levels. Insulin is a hormone produced by the pancreas that helps regulate blood sugar levels by allowing glucose to enter cells for energy. When blood sugar levels drop too low, the pancreas releases insulin to help bring them back to normal. Therefore, insulin is the hormone responsible for counteracting hypoglycemia and increasing blood sugar levels.

Hypothyroidism is a condition caused by an underactive thyroid gland, which leads to a decrease in the production of thyroid hormones. This can result in various symptoms such as fatigue, weight gain, and muscle weakness. Tétanie, which refers to muscle spasms and contractions, can be a symptom of hypothyroidism. Therefore, the correct answer is hypothyroïdie.

Calcitonin is a hormone secreted by the thyroid gland. It plays a role in regulating calcium levels in the body by inhibiting the release of calcium from the bones. This helps to maintain a balance of calcium in the blood. Therefore, the correct answer is Thyroide.

GH stands for growth hormone, which is produced by the anterior pituitary gland (antéhypophyse). It plays a crucial role in stimulating growth, cell reproduction, and regeneration in humans and other animals. GH also helps to regulate body composition, muscle and bone growth, and metabolism. Therefore, GH is the correct answer in this case.

Calcitonine et Parathormone sont les hormones qui régulent le taux de calcium dans le sang. La calcitonine diminue la concentration de calcium dans le sang en favorisant son stockage dans les os, tandis que la parathormone augmente la concentration de calcium en stimulant sa libération des os et son absorption par les reins. Ces deux hormones travaillent en équilibre pour maintenir un niveau de calcium approprié dans le corps.

The question is asking for plexus names that are not included in the given options. The options provided are cervical, lumbar, and brachial. These are all names of plexuses, but thoracic is not. Therefore, the correct answer is thoracic.

Norepinephrine is a neurotransmitter that is released from sympathetic nerves. These nerves are part of the sympathetic division of the autonomic nervous system, which is responsible for the "fight or flight" response in the body. When the body perceives a threat or stress, sympathetic nerves release norepinephrine to activate various physiological responses, such as increased heart rate, elevated blood pressure, and heightened alertness. Therefore, norepinephrine is primarily released from sympathetic nerves rather than other autonomic nerves or the parasympathetic vagus nerve.

A tract is a collection of fibers (axons) that are found in the central nervous system. The central nervous system includes the brain and spinal cord, which are responsible for receiving and processing information from the body and sending out appropriate responses. Tracts within the central nervous system allow for communication between different regions of the brain and spinal cord, enabling the transmission of sensory information, motor commands, and other signals throughout the body. Therefore, the correct answer is the central nervous system.

The majority of water in the body is found within cells. This is because cells are the fundamental units of life and contain various organelles and structures that require water for their proper functioning. Water is essential for many cellular processes such as metabolism, transportation of nutrients and waste, and maintaining cell shape and structure. While there is also water present in blood plasma, whole blood, and tissue spaces, the highest concentration of water is found within the cells themselves.

The hypothalamus is the correct answer because it plays a crucial role in regulating water intake. It contains specialized cells called osmoreceptors that monitor the concentration of solutes in the blood. When the osmoreceptors detect an increase in blood osmolality, indicating dehydration, they trigger the release of antidiuretic hormone (ADH) from the hypothalamus. ADH acts on the kidneys, increasing water reabsorption and reducing urine output, thus conserving water in the body. Additionally, the hypothalamus also stimulates thirst, prompting individuals to drink water and maintain fluid balance. Therefore, the hypothalamus is the primary regulator of water intake.

Neurons are the most sensitive cells to electrolyte changes because they are highly dependent on proper ion concentrations for their electrical signaling. Electrolyte imbalances can disrupt the balance of ions inside and outside the neurons, affecting their ability to generate and transmit electrical impulses. This can lead to various neurological symptoms and disorders. Osteoblasts are bone-forming cells, epithelial cells form the protective lining of various organs, and leukocytes are white blood cells involved in the immune response. While these cells may be affected by electrolyte changes to some extent, neurons are particularly sensitive due to their specialized electrical activity.

The correct answer is that the purpose of thermolysis is to establish a connection with the external atmosphere. This is achieved through the production of the end products of the metabolic breakdown of food and the elimination of waste products, creating a balance of concentration between the production and elimination of substances. The overall goal is to maintain homeostasis, which is achieved by regulating the concentration of substances through the processes of production and elimination.

Evaporation is the process by which a substance changes from a liquid state to a gaseous state. In this context, the given answer of 22% suggests that evaporation is responsible for 22% of the total loss of the substance.
