-Which statement about neurotransmitters is true?
A) The release of a neurotransmitter stimulates the infusion of calcium into the cell.
B) Neurotransmitters can bind to any receptor.
C) The type of neurotransmitter released determines whether an impulse continues or is stopped.
D) After an impulse is transmitted, the remaining neurotransmitter is consumed by phagocytes.

Accepted Answer

C is correct because the type of neurotransmitter released into the synaptic cleft indeed determines the response of the receiving neuron, muscle cell, or gland cell. This can either continue the impulse by exciting the receptor or stop it by inhibiting the receptor.

-When an action potential reaches a synaptic knob and the membrane depolarizes,
A) ion channels open and calcium ions enter the cell.
B) ion channels open and calcium flows out of the cell.
C) neurotransmitter release is inhibited.
D) sodium channels open and the action potential continues.

Accepted Answer

When an action potential reaches a synaptic knob, the depolarization of the membrane causes voltage-gated calcium channels to open, allowing calcium ions to enter the cell. This influx of calcium ions triggers the release of neurotransmitters into the synaptic cleft.

-To perform a lumbar puncture, physicians insert a hollow needle into the subarachnoid space between the third and fourth lumbar vertebrae and remove a sample of cerebrospinal fluid. Why do you think they choose this location for the procedure?
A) Because the vertebrae are more flexible in this location and the patient can bend forward
B) Because the spinal cord ends at the first lumbar vertebra, minimizing the risk for damaging the spinal cord
C) Because the cauda equina is in this area
D) Because there are no spinal nerves in this area, minimizing the risk for nerve injury

Accepted Answer

The spinal cord ends at the first lumbar vertebra, so choosing the location of the third and fourth lumbar vertebrae minimizes the risk for damaging the spinal cord. The cauda equina, a bundle of nerve roots that continues below the spinal cord, is also located in this area. However, this is not the primary reason for choosing this location for a lumbar puncture.

Question 9

Match each division of the autonomic nervous system with its function.
a.sympathetic division
b.parasympathetic division
-What are the consequences if a nerve lacks a neurilemma?
A) Nerve conduction is slowed.
B) Nerve conduction is accelerated.
C) The nerve cannot regenerate if injured.
D) The nerve will atrophy and die.

Accepted Answer

CThe neurilemma, also known as the Schwann cell sheath, is crucial for the regeneration of peripheral nerves. If a nerve lacks a neurilemma, it cannot effectively regenerate after injury, leading to permanent damage or loss of function in the affected nerve. This is because the neurilemma provides a conducive environment for the growth and guidance of new nerve fibers during the regeneration process.

Question 10

Match each division of the autonomic nervous system with its function.
a.sympathetic division
b.parasympathetic division
-Neurons found in the CNS that connect incoming sensory pathways with outgoing motor pathways are called:
A) Sensory neurons
B) Motor neurons
C) Multipolar neurons
D) Interneurons

Accepted Answer

Interneurons are the neurons in the central nervous system (CNS) that connect sensory neurons to motor neurons. These neurons play a critical role in the communication between different parts of the CNS and in the processing of information.

Question 11

Match each division of the autonomic nervous system with its function.
a.sympathetic division
b.parasympathetic division
-The central nervous system includes the
A) somatic motor system.
B) sympathetic division.
C) brain and spinal cord.
D) autonomic motor system.

Accepted Answer

The central nervous system (CNS) consists of the brain and spinal cord, which are responsible for processing and transmitting information throughout the body.

Question 12

Match each division of the autonomic nervous system with its function.
a.sympathetic division
b.parasympathetic division
-Which statement about nerve impulse conduction in myelinated neurons is true?
A) Myelin facilitates the free movement of ions across the cell membrane.
B) The action potential occurs only at gaps in the myelin.
C) The electrical current leaps over the myelin sheath, jumping from one node of Ranvier to the next.
D) The electrical current passes through the myelin.

-The type of neuron that has one axon and multiple dendrites is a
A) bipolar neuron.
B) unipolar neuron.
C) multipolar neuron.
D) neuroglia.

Accepted Answer

Multipolar neurons are characterized by having one axon and multiple dendrites, making them the most common type of neuron in the nervous system. This structure allows for the integration of a lot of information from other neurons.

Question 14

Match each division of the autonomic nervous system with its function.
a.sympathetic division

-The division of the nervous system that carries signals from nerve endings to the central nervous system is the
A) sensory (afferent) division.
B) motor (efferent) division.
C) sympathetic division.
D) parasympathetic division.

Accepted Answer

The sensory (afferent) division of the nervous system is responsible for carrying signals from nerve endings to the central nervous system. This division is distinct from the sympathetic and parasympathetic divisions, which are parts of the autonomic nervous system involved in regulating involuntary body functions, such as heart rate and digestion, not in carrying signals to the central nervous system.

Question 15

Match each division of the autonomic nervous system with its function.
a.sympathetic division
b.parasympathetic division
-The part of the nervous system that carries signals from the skin, bones, joints, and muscles to the central nervous system is the
A) autonomic motor.
B) somatic motor.
C) visceral sensory.
D) somatic sensory.

Accepted Answer

The somatic sensory system is responsible for processing sensory information from the skin, bones, joints, and muscles, conveying it to the central nervous system. This system allows us to perceive touch, pain, temperature, and proprioception (the sense of body position and movement).
