SECTION 1: NERVOUS SYSTEM — ORGANIZATION & CELLS
(Questions)
Nervous System Divisions
1. The nervous system is divided into which two main
anatomical divisions?
A) Somatic and autonomic
B) Central and peripheral
C) Sympathetic and parasympathetic
D) Sensory and motor
Correct Answer: B
Rationale: The nervous system is divided into the central
nervous system (CNS), consisting of the brain and spinal cord,
,and the peripheral nervous system (PNS), consisting of all
neural tissue outside the CNS.
2. What makes up the central nervous system (CNS)?
A) Brain and spinal cord
B) Cranial nerves and spinal nerves
C) Sympathetic and parasympathetic divisions
D) Sensory and motor neurons
Correct Answer: A
Rationale: The CNS consists of the brain and spinal cord,
located within the cranial and vertebral cavities.
3. What makes up the peripheral nervous system (PNS)?
A) Brain and spinal cord
B) All neural tissue outside the CNS
C) Only cranial nerves
D) Only spinal nerves
Correct Answer: B
Rationale: The PNS consists of all neural tissue outside the CNS,
including nerves, nerve plexuses, cranial nerves (12 pairs), and
spinal nerves (31 pairs).
4. The somatic nervous system controls which of the
following?
A) Smooth muscle and glands
B) Skeletal muscles
,C) Cardiac muscle
D) Adipose tissue
Correct Answer: B
Rationale: The somatic nervous system controls skeletal
muscles and is concerned with conscious perception, voluntary
movement, and skeletal muscle reflexes.
5. The autonomic nervous system (ANS) controls all of the
following EXCEPT:
A) Smooth muscle
B) Cardiac muscle
C) Glands
D) Skeletal muscle
Correct Answer: D
Rationale: The ANS controls smooth muscle, cardiac muscle,
glands, and adipose tissue—involuntary effectors. Skeletal
muscle is controlled by the somatic nervous system.
6. The sympathetic nervous system is responsible for:
A) Rest and digest responses
B) Fight or flight responses
C) Voluntary movement
D) Conscious perception
Correct Answer: B
Rationale: The sympathetic nervous system mediates the "fight
, or flight" response, preparing the body for vigorous emergency
activity.
7. The parasympathetic nervous system is responsible for:
A) Fight or flight responses
B) Rest and digest responses
C) Emergency responses
D) Skeletal muscle contraction
Correct Answer: B
Rationale: The parasympathetic nervous system mediates "rest
and digest" responses, slowing the body down and promoting
digestion and relaxation.
8. The enteric nervous system (ENS) is best described as:
A) The brain of the gut
B) The voluntary nervous system
C) The fight or flight system
D) The sensory division
Correct Answer: A
Rationale: The enteric nervous system is often called the "brain
of the gut" and controls gastrointestinal function independently
of the CNS.
9. The sensory (afferent) division of the PNS:
A) Carries motor commands to effectors
B) Carries sensory input to the CNS
