Trivia Quiz On Human Anatomy And Nervous System!

the central nervous system is composed of the brain and the spinal cord.

a neuron is made up of one axon, a cell body, and several dendrites

interneurons are neurons situated between two other neurons in a neutral pathway, may be sensory or motor have very short axon

the junction between two neurons, axodendritic, axosomatic, axoaxonic is called a synapse

The autonomic Nervous system includes the parasympathetic and sympathetic systems

The dendrites are extensions of the cell body that receive signals from other neurons and transmit them towards the cell body. The term "dendrite" comes from the Greek word meaning tree, which reflects their branching structure. Dendrites play a crucial role in forming synapses, which are the connections between neurons where information is transmitted. Therefore, the dendrites fit the given description as they can be multiple per cell body, have a tree-like structure, and participate in the formation of synapses.

motor neurons are known as efferent, carry information away from the brain to the receptor.

The occipital lobe is responsible for visual reception and association, visual memory, recognition, and understanding of the environment. It is located at the back of the brain and is primarily involved in processing visual information received from the eyes. This lobe plays a crucial role in perceiving and interpreting visual stimuli, allowing us to recognize objects, understand spatial relationships, and form visual memories.

carpal tunnel syndrome, brachail plexus injury and Avulsion of the digital nerve are examples of failure of the Peripheral nervous system?

Myocardial infarction, congestive heart failure chronic obstructive pulmonary disease COPD, Diabetes - typer I and II are examples of failure of the autonomic nervous system?

The axon is a long, slender projection of a neuron that carries electrical impulses away from the cell body. It is responsible for transmitting these impulses to other neurons, muscles, or cells. Axons can vary in length and can be classified as either myelinated or non-myelinated. At the end of the axon, there are synapse knobs which produce either a transmitter or an inhibitory response. Therefore, the axon is the correct answer as it aligns with all the given characteristics.

The term "axoaxonic" refers to the junction between the axon of one neuron with the axon of another neuron. This means that the synapse occurs between two axons rather than between an axon and a dendrite or soma. Axoaxonic synapses are less common than axodendritic or axosomatic synapses, but they play important roles in modulating the activity of the postsynaptic neuron. They can either enhance or inhibit the transmission of signals between neurons, depending on the specific neurotransmitters involved.

The temporal lobe is responsible for auditory reception and association, spoken language memory, non-language sounds (music), some emotion, and personality aspects. This is supported by the fact that the temporal lobe contains the primary auditory cortex, which processes sound information, and the Wernicke's area, which is involved in language comprehension. Additionally, damage to the temporal lobe can result in difficulties with language and auditory processing, further confirming its role in these functions.

The conditions listed in the question, including Cerebral Vascular Accident (CVA), Parkinson's disease, Guillain-Barre' Syndrome, and C5-6 spinal cord injury, all affect the central nervous system. These conditions involve damage or dysfunction in the brain, spinal cord, or both, which are part of the central nervous system. Therefore, the correct answer is central.

axosomatic, and axoaxonic synapses describe the junction between the axon of one neuron with the dendrite of another neuron.

Injury to upper motor neurons can result in diffuse decreased muscle function. Upper motor neurons are responsible for transmitting signals from the brain to the lower motor neurons, which then activate the muscles. When upper motor neurons are damaged, the communication between the brain and muscles is disrupted, leading to a decrease in muscle function throughout the body. This can manifest as weakness, decreased coordination, and difficulty with movement.

The frontal lobe is responsible for voluntary motor activity, concentration, motivation, problem solving, planning, intellectual function, memory, abstraction, and expressive speech.

A nueron is basic unit of the nervous system, is both structural and functional, is a non-dividing cell.

Lower motor neurons are responsible for transmitting signals from the spinal cord to the muscles, controlling their movement. When these neurons are injured, there is a localized decrease in muscle function because the signals from the spinal cord cannot reach the muscles properly. Upper motor neurons, on the other hand, are responsible for transmitting signals from the brain to the lower motor neurons. However, injury to upper motor neurons would not directly result in localized decreased muscle function as their role is to modulate and refine the signals sent by the lower motor neurons.

The correct answer is 1. cerebellum 2)diencephalons (thalamus & hypothalamus) 3)Midbrain 4)Pons 5)medulla 6)cerebrum 7) spinal cord. This is the correct order of the seven regions of the central nervous system. The cerebellum is responsible for coordination and balance, while the diencephalons contain important structures like the thalamus and hypothalamus. The midbrain, pons, and medulla are all part of the brainstem and play important roles in relaying and controlling signals between the brain and the rest of the body. The cerebrum is the largest part of the brain and is responsible for higher cognitive functions. Finally, the spinal cord connects the brain to the peripheral nervous system.

The correct answer is "all of the above". A nerve impulse refers to the transmission of signals between neurons, which involves the secretion of neurotransmitters from one neuron to another. These neurotransmitters can have either excitatory or inhibitory effects on the receiving neuron. Additionally, nerve impulses move along specific pathways called nerve tracts. Therefore, all the given statements are true and encompass the concept of a nerve impulse.

The purpose of the Central Nervous System is to process sensory information and provide a response. The Central Nervous System receives sensory input from various parts of the body and processes this information to make sense of it. It then sends signals to the appropriate muscles or organs to generate a response or action. This allows the body to react to its environment and maintain homeostasis.

Sensory Neurons are also known as afferent, carry sensory information from the receptor to the brain, there are always 3 neurons between any receptor and the cortex.

The sensory neuron cell body is located in the spinal nerves, the cranial nerves and the thalmus. contains organelles whose overall function is to keep the neurons alive"

is the cell body

OTs and OTA's study Neuro Anatomy because understanding the integration of sensory information is crucial in their field. When any component of the nervous system is unable to perform, the body cannot effectively integrate sensory information. This knowledge allows OTs to assess and treat patients with injuries to the neuro-motor system, such as CVA, spinal cord injuries, and TBI's. Specializing in this area provides an economical advantage as the demand for OTs with expertise in neuro-motor system injuries increases. Additionally, all components of the nervous system are interconnected, so damage to one component can affect others, leading to system failures.

The parietal lobe is responsible for tactile processing, body awareness and scheme, language comprehension, some concept formation, gnosis, and praxis. This is supported by research and studies that have shown the involvement of the parietal lobe in these functions.

Medulla midbrain and pons make up the brain stem

The lower motor neuron is a neuron whose cell body is located in the spinal cord or brainstem and whose axon extends out to the muscles or glands. It is responsible for carrying signals from the central nervous system to the peripheral nervous system to initiate muscle contractions or glandular secretions. Therefore, the statement that the lower motor neuron's cell body is in the cerebral cortex and its axons descend to the spinal cord is incorrect.

The cerebrum consists of various structures, including the cerebral cortex, tracts, basil ganglia, and corpus collosum. However, the cerebellum is not part of the cerebrum. The cerebellum is a separate structure located at the back of the brain, responsible for coordinating voluntary movements, balance, and posture.

The brain stem is located at the bottom of the skull and is responsible for our primitive reflexes. This means that the correct answer is both A and B, as the brain stem is involved in both the location and function described.

the correct answer is: the lower neuron is neuron whose cell body is located in the spinal cord that control the skeletal muscles in the trunk and upper/lower extremities

Parasympathetic include: Cranial nerves III, IV, IX, X and terminal ganglia
