Learning
1. The central nervous system consists of which structures?
A) Brain and spinal cord
B) Brain and cranial nerves
C) Spinal cord and peripheral nerves
D) Cranial nerves and spinal nerves
Correct Answer: Brain and spinal cord
Rationale: The central nervous system consists of the brain and spinal cord.
The peripheral nervous system includes all nerves outside the CNS, including
cranial and spinal nerves .
2. The peripheral nervous system includes which structures?
A) Brain and spinal cord
B) Only cranial nerves
C) Cranial nerves and spinal nerves
D) Spinal cord only
Correct Answer: Cranial nerves and spinal nerves
Rationale: The PNS consists of cranial nerves and spinal nerves. The brain
and spinal cord are part of the CNS. This organization is fundamental to
understanding nervous system structure.
3. Which division of the nervous system carries information from the
periphery to the central nervous system?
A) Motor division
,B) Efferent division
C) Sensory (afferent) division
D) Somatic division
Correct Answer: Sensory (afferent) division
Rationale: The sensory (afferent) division carries information from the
periphery to the CNS. The motor (efferent) division carries signals from the
CNS to muscles and glands .
4. Which division of the nervous system carries information from the central
nervous system to muscles and glands?
A) Sensory division
B) Afferent division
C) Motor (efferent) division
D) Autonomic division
Correct Answer: Motor (efferent) division
Rationale: The motor (efferent) division carries signals from the CNS to
muscles and glands. Sensory/afferent division carries information toward the
CNS. This is a fundamental distinction in nervous system organization.
5. The somatic nervous system controls which type of structures?
A) Smooth muscle and glands
B) Cardiac muscle
C) Skeletal muscles
D) Internal organs
, Correct Answer: Skeletal muscles
Rationale: The somatic nervous system controls skeletal muscles, which are
under voluntary control. The autonomic nervous system controls smooth
muscle, cardiac muscle, and glands .
6. Which division of the autonomic nervous system prepares the body for
stress and emergencies?
A) Parasympathetic nervous system
B) Sympathetic nervous system
C) Somatic nervous system
D) Enteric nervous system
Correct Answer: Sympathetic nervous system
Rationale: The sympathetic nervous system prepares the body for vigorous
muscular activity, stress, and emergencies, often called "fight or flight." The
parasympathetic system operates during normal situations .
7. Which division of the autonomic nervous system calms the body and
conserves energy?
A) Sympathetic nervous system
B) Parasympathetic nervous system
C) Somatic nervous system
D) Enteric nervous system
Correct Answer: Parasympathetic nervous system
