TEAS Practice Test: Anatomy & Physiology
(Nervous System)
Section: Nervous System
1. The part of the nervous system shown in the diagram is primarily the:
(Diagram: Full-body nerve branching diagram showing spinal cord and peripheral nerves to
limbs)
a. somatic
b. autonomic
c. sympathetic
d. parasympathetic
✅ Correct Answer: A (somatic)
Rationale:
The diagram shows nerves extending from the spinal cord into the limbs and skeletal muscles,
which is characteristic of the somatic nervous system. The somatic system controls voluntary
movement and carries sensory information from the skin, muscles, and joints to the CNS. The
autonomic system instead regulates involuntary functions such as heart rate and digestion.
2. Which of the following are the two major parts of the nervous system?
a. Autonomic nervous system and somatic nervous system
b. Peripheral nervous system and somatic nervous system
c. Peripheral nervous system and central nervous system
d. Autonomic nervous system and central nervous system
✅ Correct Answer: C (Peripheral nervous system and central nervous system)
Rationale:
The nervous system is divided into two main components:
Central Nervous System (CNS): brain and spinal cord
Peripheral Nervous System (PNS): all nerves outside the CNS
The PNS connects the CNS to the rest of the body.
3. Which of the following parts of the brain is primarily responsible for
coordination and balance?
(Diagram: Brain with labeled regions: cerebrum, cerebellum, brainstem)
a. Cerebrum
b. Cerebellum
c. Medulla oblongata
d. Hypothalamus
✅ Correct Answer: B (Cerebellum)
Rationale:
The cerebellum controls balance, posture, and coordination of voluntary movements.
Damage to the cerebellum can cause difficulty walking, tremors, and poor muscle coordination.
The cerebrum controls higher thinking, the medulla controls autonomic functions like breathing,
and the hypothalamus regulates homeostasis.
4. Which of the following structures is most likely responsible for pain
perception?
a. Cerebellum
b. Occipital lobe
c. Thalamus
d. Parietal lobe
✅ Correct Answer: D (Parietal lobe)
Rationale:
The parietal lobe contains the primary somatosensory cortex, which processes sensations such
as pain, temperature, pressure, and touch. The thalamus relays sensory information, but the
parietal cortex is where perception occurs.
