    The resting potential of a neuron is:?

    • -70 mv

    • +30 mv

    • 0 mv

    • -90 mv

    Correct Answer
    A. -70 mv
    Explanation
    The resting potential of a neuron refers to the electrical charge across the cell membrane when the neuron is at rest and not transmitting signals. The correct answer, -70 mv, indicates that the inside of the neuron is negatively charged compared to the outside. This negative charge is maintained by the balance of ions, with more negatively charged ions inside the neuron and more positively charged ions outside. This potential allows the neuron to quickly transmit electrical signals when stimulated.

    The minimal stimulus needed to cause a neuron to transmit an impulse is called the:?

    • Threshold

    • Action potential

    • Resting potential

    • Refractory period

    Correct Answer
    A. Threshold
    Explanation
    The correct answer is threshold. The threshold is the minimum level of stimulation required for a neuron to transmit an impulse. Once the stimulus reaches or exceeds the threshold, the neuron generates an action potential, which is the electrical signal that travels down the neuron. The resting potential refers to the electrical charge of a neuron when it is at rest, and the refractory period is the brief period after an action potential when the neuron is unable to generate another impulse.

    A change in a dendrite which lessens the probability of a conduction is:?

    • Inhibitatory Post-Synaptic Potential

    • Excitatory Post-Synaptic Potentia

    • Threshold potential

    • Action potential

    Correct Answer
    A. Inhibitatory Post-Synaptic Potential
    Explanation
    A change in a dendrite which lessens the probability of conduction is called an Inhibitatory Post-Synaptic Potential (IPSP). This refers to a decrease in the electrical potential of a neuron following the release of inhibitory neurotransmitters. IPSPs make it less likely for the neuron to generate an action potential and transmit signals to other neurons. It acts as a braking mechanism, inhibiting the firing of an action potential and reducing the overall excitability of the neuron.

    The following belong together EXCEPT which one?

    • Multipolar

    • Efferent

    • Sensory

    • Motor

    Correct Answer
    A. Multipolar
    Explanation
    The terms "efferent," "sensory," and "motor" all relate to the nervous system and its functions. Efferent refers to nerves that carry signals away from the central nervous system, sensory refers to nerves that transmit sensory information to the central nervous system, and motor refers to nerves that control muscle movement. However, "multipolar" does not specifically relate to the nervous system. It is a term used in biology to describe a cell with multiple processes or extensions. Therefore, "multipolar" is the odd one out among the given options.

    The PNS is comprised of cranial nerves and:

    • Spinal nerves

    • Motor nerves

    • Sensory nerves

    • Somatic nerves

    Correct Answer
    A. Spinal nerves
    Explanation
    The correct answer is spinal nerves. The peripheral nervous system (PNS) is made up of the cranial nerves, which originate from the brain, and the spinal nerves, which originate from the spinal cord. The spinal nerves are responsible for transmitting sensory information from the body to the central nervous system and for carrying motor commands from the central nervous system to the muscles and glands. Therefore, including spinal nerves as part of the PNS is an accurate statement.

    Rate this question:

  • 7. 

    A common feature of action potentials is that they:?

    • Are triggered by a depolarization that reaches the threshold.

    • Cause the membrane to hyperpolarize and then depolarize.

    • Can undergo temporal and spatial summation.

    • Move at the same speed along all axons.

    Correct Answer
    A. Are triggered by a depolarization that reaches the threshold.
    Explanation
    Action potentials are electrical signals that are generated and transmitted by neurons. They are initiated when the membrane potential of a neuron reaches a certain threshold level of depolarization. Once the threshold is reached, an action potential is triggered and a rapid depolarization occurs, resulting in the propagation of the electrical signal along the axon. Therefore, the correct answer states that action potentials are triggered by a depolarization that reaches the threshold.

    Rate this question:

  • 8. 

    The membrane closest to the brain is:?

    • Pia mater

    • Dura mater

    • Arachnoid meninx

    • Denticulate ligament

    Correct Answer
    A. Pia mater
    Explanation
    The pia mater is the innermost membrane that covers the brain and spinal cord. It is a thin, delicate layer that is in direct contact with the brain. It is responsible for providing nourishment to the brain through its network of blood vessels. The dura mater and arachnoid meninx are also membranes that surround the brain but are located outside the pia mater. The denticulate ligament is a structure within the spinal cord and is not directly related to the brain. Therefore, the correct answer is pia mater.

    Rate this question:

  • 9. 

    An inflammation of the brain coverings is termed:?

    • Meningitis

    • Encephalitis

    • Poliomyelitis

    • Cerebral palsy

    Correct Answer
    A. Meningitis
    Explanation
    Meningitis is the correct answer because it refers to the inflammation of the brain coverings, specifically the meninges. This condition can be caused by viral, bacterial, or fungal infections, and it commonly presents with symptoms such as fever, headache, neck stiffness, and sensitivity to light. Prompt diagnosis and treatment are crucial to prevent complications and potential long-term effects. Encephalitis, on the other hand, refers to inflammation of the brain itself, while poliomyelitis is a viral infection that affects the spinal cord. Cerebral palsy is a non-progressive neurological disorder that affects movement and posture.

    What is first component of reflex arch?

    • Sensory neuron

    • Motor neuron

    • Muscle or glance

    • Interneuron

    Correct Answer
    A. Sensory neuron
    Explanation
    The first component of a reflex arc is the sensory neuron. This neuron is responsible for transmitting sensory information from the sensory receptors to the central nervous system (CNS). In a reflex arc, when a stimulus is detected by the sensory receptors, the sensory neuron carries the information to the CNS, where it is processed. This information then triggers a response, which is carried out by the motor neuron. Therefore, the sensory neuron is the initial component of the reflex arc, playing a crucial role in the transmission of sensory information.

    Acetylcholine is decomposed by _____almost as fast as it is released.?

    • Acetylcholinesterase

    • Monoamine oxidase

    • MAO inhibitors

    • Norepinephrine

    Correct Answer
    A. Acetylcholinesterase
    Explanation
    Acetylcholine is a neurotransmitter that is responsible for transmitting signals between nerve cells. It is released into the synaptic cleft and needs to be quickly broken down to prevent continuous stimulation of the postsynaptic cell. Acetylcholinesterase is an enzyme that rapidly decomposes acetylcholine, ensuring that it is cleared from the synaptic cleft. Therefore, acetylcholinesterase decomposes acetylcholine almost as fast as it is released.

    The greatest amount of body water is lost through:

    • Urine

    • Sweating

    • Defecation

    • Breathing

    Correct Answer
    A. Urine
    Explanation
    The greatest amount of body water is lost through urine because it is the primary way in which the body eliminates waste and excess water. Urine is produced by the kidneys, which filter waste products from the blood and remove them from the body through the urinary system. This process helps maintain the body's water balance and remove toxins. While sweating, defecation, and breathing also contribute to water loss, they are not as significant as urine in terms of the overall amount of water lost by the body.

    Explanation
    The explanation for the given answer is that thermogenesis is the process by which the body produces heat. It is primarily driven by the metabolic activity of brown adipose tissue (BAT) and the activation of uncoupling proteins (UCPs). When the body is exposed to cold temperatures or when there is an increase in energy expenditure, thermogenesis is activated to generate heat and maintain body temperature. This process is regulated by various mechanisms that ensure a balance between heat production and heat dissipation, ultimately aiming to maintain a core body temperature of around 37oC.
