Question 1

Which of the following best describes the primary function of the central nervous system (CNS)?

Accepted Answer

To serve as the command center that interprets incoming sensory information and issues outgoing instructions.

Question 2

A patient presents with loss of sensation in the skin and inability to move skeletal muscles. Which division of the nervous system is most likely affected?

Accepted Answer

Peripheral nervous system (PNS)

Question 3

Which of the following is TRUE regarding the structural classification of the nervous system?

Accepted Answer

The CNS is responsible for integration and control of voluntary and involuntary movements.

Question 4

Which of the following best explains the process of integration in the nervous system?

Accepted Answer

The central nervous system processes sensory information and decides whether action is needed to maintain homeostasis.

Question 5

A person touches a hot surface and immediately withdraws their hand. Which sequence correctly describes the flow of information in the nervous system?

Accepted Answer

Sensory input → Integration → Motor output

Question 6

Which of the following is NOT a function of the peripheral nervous system (PNS)?

Accepted Answer

Interpreting incoming sensory information

Question 7

Which of the following best describes the role of sensory receptors in the nervous system?

Accepted Answer

They monitor changes called stimuli from the internal and external environment.

Question 8

If the peripheral nerves fail to relay information to the central nervous system, which of the following would most likely occur?

Accepted Answer

Sensory input would be gathered but not processed or responded to.

Question 9

Which of the following is the correct anatomical term for the bundle of nerve fibers found in the peripheral nervous system?

Accepted Answer

Nerve

Question 10

Which function of the nervous system is directly responsible for controlling heartbeat, breathing patterns, and digestion?

Accepted Answer

Motor output

Question 11

A researcher is studying the effects of a drug that impairs the ability of the CNS to issue outgoing instructions. Which physiological process would be most directly affected?

Accepted Answer

Control of voluntary and involuntary movements

Question 12

Which of the following best describes the relationship between the CNS and PNS?

Accepted Answer

The CNS interprets sensory information and the PNS relays information between the CNS and the rest of the body.

Question 13

Which equation best represents the flow of information in the nervous system?

Accepted Answer

$$	ext{Sensory Input} ightarrow 	ext{Integration} ightarrow 	ext{Motor Output}$$

Question 14

Which of the following is a correct example of sensory input in the nervous system?

Accepted Answer

Sensory receptors detecting a change in temperature.

Question 15

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

Accepted Answer

The CNS integrates sensory information and controls both voluntary and involuntary movements.
