Domain 1: Nervous System Organization & Divisions
(60 Questions)
Question 1
What are the two primary divisions of the human nervous system?
A) Somatic and Autonomic
B) Central and Peripheral
C) Sympathetic and Parasympathetic
D) Afferent and Efferent
Correct Answer: B) Central and Peripheral
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. The other options describe functional subdivisions of the PNS, not
the primary structural divisions.
---
Question 2
The brain and spinal cord together make up which division of the nervous system?
A) Peripheral nervous system
B) Autonomic nervous system
, C) Central nervous system
D) Somatic nervous system
Correct Answer: C) Central nervous system
Rationale: The central nervous system (CNS) consists exclusively of the brain and spinal cord.
These structures serve as the integration and command centers of the nervous system,
processing sensory information and generating motor commands.
---
Question 3
A patient voluntarily contracts the quadriceps femoris to extend the knee while walking.
Which division of the nervous system controls this conscious movement?
A) Autonomic nervous system
B) Somatic nervous system
C) Sympathetic nervous system
D) Parasympathetic nervous system
Correct Answer: B) Somatic nervous system
Rationale: The somatic nervous system controls voluntary contractions of skeletal muscles
through somatic motor neurons. When you consciously decide to walk or lift an object, the
somatic nervous system carries motor commands from the CNS to skeletal muscles.
