Question 1

Which of the following best describes the main function of the nervous system?

Accepted Answer

To receive, integrate, and respond to information via electrical and chemical signals

Question 2

A person touches a hot stove and immediately pulls their hand away. Which sequence correctly describes the flow of information in the nervous system for this reflex?

Accepted Answer

Sensory input → Integration → Motor output

Question 3

Which division of the nervous system is responsible for interpreting sensory input and dictating motor output?

Accepted Answer

Central nervous system (CNS)

Question 4

The peripheral nervous system (PNS) consists mainly of:

Accepted Answer

Nerves that extend from the brain and spinal cord

Question 5

Which of the following is TRUE about the somatic nervous system?

Accepted Answer

It transmits impulses from the CNS to skeletal muscle under conscious control

Question 6

A patient is unable to consciously move their arm muscles. Which part of the nervous system is most likely affected?

Accepted Answer

Somatic nervous system

Question 7

Which of the following best describes the sensory (afferent) division of the PNS?

Accepted Answer

It conveys impulses from sensory receptors to the CNS

Question 8

The autonomic nervous system (ANS) regulates which of the following?

Accepted Answer

Smooth muscle, cardiac muscle, and glands

Question 9

Which of the following is a correct pairing of nervous system division and its function?

Accepted Answer

Autonomic nervous system – controls involuntary actions

Question 10

If a person’s visceral sensory fibers are damaged, which function would be most affected?

Accepted Answer

Transmission of impulses from internal organs to the CNS

Question 11

Which of the following best explains why the nervous system can cause almost immediate responses?

Accepted Answer

It uses rapid and specific electrical and chemical signals

Question 12

Which of the following is NOT a function of the nervous system?

Accepted Answer

Production of red blood cells

Question 13

Which of the following divisions of the nervous system is responsible for the 'fight or flight' response?

Accepted Answer

Sympathetic division of the autonomic nervous system

Question 14

Which of the following statements about the enteric nervous system is correct?

Accepted Answer

It consists of neurons in the walls of the gastrointestinal tract

Question 15

A researcher stimulates a nerve and observes activation of skeletal muscle. Which division of the nervous system is being tested?

Accepted Answer

Somatic nervous system

Question 16

Which of the following best describes the role of effectors in the nervous system?

Accepted Answer

They are activated by motor output to produce a response

Question 17

Which of the following is a correct description of the flow of information in the nervous system?

Accepted Answer

Sensory input → Integration → Motor output → Effector

Question 18

Which of the following is TRUE regarding the central nervous system (CNS)?

Accepted Answer

It is the integration and control center of the body

Question 19

Which of the following would most likely be affected if the motor (efferent) division of the PNS is damaged?

Accepted Answer

Ability to activate muscles and glands

Question 20

Which of the following best describes the difference between the somatic and autonomic nervous systems?

Accepted Answer

Somatic controls voluntary skeletal muscle; autonomic regulates involuntary actions of smooth muscle, cardiac muscle, and glands
