Question 1

Match the part of the autonomic nervous system, labelled a. through d., with its description(s). (Options may be used more than once or not at all.)
-predominates in relaxed situations

Accepted Answer

The parasympathetic nervous system predominates in relaxed situations.

Question 2

Match the part of the autonomic nervous system, labelled a. through d., with its description(s). (Options may be used more than once or not at all.)
-has a short preganglionic fibre and a long postganglionic fibre

Accepted Answer

A describes the sympathetic nervous system, which has a short preganglionic fibre and a long postganglionic fibre.

Answer: B 
 B describes the parasympathetic nervous system, which has a long preganglionic fibre and a short postganglionic fibre.

Answer: C 
 C is correct because both the sympathetic and parasympathetic nervous systems have distinct features, including the length of their preganglionic and postganglionic fibers.

Answer: D 
 D is incorrect because all parts of the autonomic nervous system are either sympathetic or parasympathetic in nature. There is no part of the autonomic nervous system that is neither sympathetic nor parasympathetic.

Question 3

Match the part of the autonomic nervous system, labelled a. through d., with its description(s). (Options may be used more than once or not at all.)
-postganglionic fibre that secretes acetylcholine

Accepted Answer

Postganglionic fibres of the parasympathetic nervous system secrete acetylcholine.

Question 4

Match the part of the autonomic nervous system, labelled a. through d., with its description(s). (Options may be used more than once or not at all.)
-postganglionic fibre that secretes norepinephrine

Accepted Answer

Postganglionic fibres that secrete norepinephrine are part of the sympathetic nervous system.

Question 5

Match the part of the autonomic nervous system, labelled a. through d., with its description(s). (Options may be used more than once or not at all.)
-predominates in fight-or-flight situations

Accepted Answer

The sympathetic nervous system predominates in fight-or-flight situations.

Answer: B 
 The parasympathetic nervous system does not predominate in fight-or-flight situations.

Answer: C 
 Both the sympathetic and parasympathetic nervous systems are part of the autonomic nervous system, but they have different functions. The sympathetic nervous system predominates in fight-or-flight situations, while the parasympathetic nervous system predominates in rest-and-digest situations.

Answer: D 
 This option is not applicable as all parts of the autonomic nervous system are either sympathetic, parasympathetic, or both.

Question 6

Match the part of the autonomic nervous system, labelled a. through d., with its description(s). (Options may be used more than once or not at all.)
-originates in the cranial and sacral regions of the CNS

Accepted Answer

The parasympathetic nervous system originates in the cranial and sacral regions of the central nervous system (CNS), distinguishing it from the sympathetic nervous system, which originates in the thoracic and lumbar regions.

Question 7

Accepted Answer

The answer of Match the structures, labelled a. through h.,...

Question 8

Match the part of the autonomic nervous system, labelled a. through d., with its description(s). (Options may be used more than once or not at all.)
-innervates smooth muscle, cardiac muscle, and exocrine glands

Accepted Answer

Both the sympathetic and parasympathetic nervous systems innervate smooth muscle, cardiac muscle, and exocrine glands as part of their role in regulating involuntary body functions.

Question 9

Match the structures, labelled a. through h., with their proper sequence of involvement in the visual pathway.
-eighth

Accepted Answer

The answer of Match the structures, labelled a. through h.,...

Question 10

Match the part of the autonomic nervous system, labelled a. through d., with its description(s). (Options may be used more than once or not at all.)
-has a long preganglionic fibre and a short postganglionic fibre

Accepted Answer

The parasympathetic nervous system has a long preganglionic fibre and a short postganglionic fibre.

Question 11

Match the type of neuron, labelled a. through d., with its description(s). (Options may be used more than once or not at all.)
-autonomic nerves

Accepted Answer

The type of neuron labelled a. through d. can either be efferent neurons or interneurons. Autonomic nerves cannot be accurately matched with one of the labels since they are a type of nerve that carries involuntary impulses to the smooth muscle, cardiac muscle, and various glands. Afferent neurons carry sensory information to the central nervous system, while efferent neurons carry motor signals away from the central nervous system to the muscles, organs, and glands. Interneurons, on the other hand, work as a bridge between sensory and motor neurons. All three types of neurons (afferent, efferent, and interneurons) may be present in the nervous system. Therefore, the best choice is D, which encompasses both efferent neurons and interneurons.

Question 12

Match the part of the autonomic nervous system, labelled a. through d., with its description(s). (Options may be used more than once or not at all.)
-innervates skeletal muscle

Accepted Answer

The autonomic nervous system is responsible for controlling involuntary actions such as heart rate, breathing, and digestion. It is divided into the sympathetic and parasympathetic nervous systems, which typically have opposing effects on these functions. However, neither system innervates skeletal muscle, which is under the control of the somatic nervous system. Therefore, the correct choice is D: neither sympathetic nor parasympathetic nervous system.

Question 13

Match the structures, labelled a. through h., with their proper sequence of involvement in the visual pathway.
-sixth

Accepted Answer

The answer of Match the structures, labelled a. through h.,...

Question 14

Match the structures, labelled a. through h., with their proper sequence of involvement in the visual pathway.

Accepted Answer

The answer of Match the structures, labelled a. through h.,...

Question 15

Match the part of the autonomic nervous system, labelled a. through d., with its description(s). (Options may be used more than once or not at all.)
-preganglionic fibre that secretes norepinephrine

Accepted Answer

Preganglionic fibers in both the sympathetic and parasympathetic nervous systems secrete acetylcholine, not norepinephrine. Norepinephrine is typically secreted by postganglionic fibers in the sympathetic nervous system.

Question 16

Match the type of neuron, labelled a. through d., with its description(s). (Options may be used more than once or not at all.)
-have a receptor at the peripheral ending

Accepted Answer

Afferent neurons, also known as sensory neurons, have receptors at their peripheral endings that are responsible for converting external stimuli into internal electrical impulses. These neurons carry information from sensory receptors to the central nervous system.

Question 17

Match the structures, labelled a. through h., with their proper sequence of involvement in the visual pathway.
-fifth

Accepted Answer

The answer of Match the structures, labelled a. through h.,...

Question 18

Match the part of the autonomic nervous system, labelled a. through d., with its description(s). (Options may be used more than once or not at all.)
-preganglionic fibre that secretes acetylcholine

Accepted Answer

Both the sympathetic and parasympathetic nervous systems use acetylcholine as the neurotransmitter for their preganglionic fibers.

Question 20

Match the part of the autonomic nervous system, labelled a. through d., with its description(s). (Options may be used more than once or not at all.)
-originates in the thoracic and lumbar regions of the CNS

Accepted Answer

The sympathetic nervous system originates in the thoracic and lumbar regions of the CNS.

Answer: B
 The parasympathetic nervous system does not originate in the thoracic and lumbar regions of the CNS, so options C and D are not correct.
