BIOD 152 MODULE 2 — ANATOMY &
PHYSIOLOGY II QUESTIONS WITH VERIFIED
SOLUTIONS AND RATIONALES
1. This region of the brain acts to coordinate multiple sources of sensory
information.
A. Primary sensory cortex
B. Association area
C. Motor cortex
D. Cerebellum
Correct Answer: B
Rationale: Association areas process and integrate input from multiple sensory
modalities to produce perception and meaningful responses .
2. The _____ fissure separates the cerebrum from the cerebellum.
A. Longitudinal
B. Central
C. Transverse
D. Lateral
,2|Page
Correct Answer: C
Rationale: The transverse fissure (also called the transverse cerebral fissure) is the
deep groove that separates the cerebrum from the cerebellum .
3. This is the most superficial layer of the brain meninges.
A. Dura mater
B. Arachnoid mater
C. Pia mater
D. Subarachnoid space
Correct Answer: A
Rationale: The dura mater is the toughest, outermost layer of the meninges
protecting the brain and spinal cord. It provides a durable protective covering,
distinguishing it from the more delicate arachnoid mater and pia mater beneath .
4. A patient is having difficulty understanding language but can still speak fluently.
The patient's dermatomes are intact. Which area of the brain is most likely
damaged?
A. Broca's area
B. Wernicke's area
,3|Page
C. Primary motor cortex
D. Somatosensory cortex
Correct Answer: B
Rationale: Wernicke's area is responsible for language comprehension; damage
leads to fluent but nonsensical speech and poor understanding .
5. What is muscle tone and how is it maintained?
A. The degree at which muscles remain partially contracted while at rest;
maintained by the cerebellum
B. The degree at which muscles are fully relaxed; maintained by the medulla
C. The force of muscle contraction; maintained by the motor cortex
D. The speed of muscle contraction; maintained by the basal ganglia
Correct Answer: A
Rationale: Muscle tone is the degree at which muscles remain partially contracted
while at rest. Muscle tone is continuously monitored and maintained by the
cerebellum to keep bones and joints in place .
6. Which statement is false concerning the brainstem?
A. The midbrain processes visual and auditory reflexes.
, 4|Page
B. The midbrain portion of the brainstem is continuous with the spinal cord.
C. The brainstem contains centers for cardiovascular and respiratory control.
D. The pons connects the cerebellum with the brainstem.
Correct Answer: B
Rationale: The brainstem is continuous with the spinal cord at the medulla
oblongata, not the midbrain .
7. Which of the following is true concerning the cerebellum?
A. The cerebellum controls voluntary muscle force only.
B. The anterior lobe receives information from the body trunk.
C. The cerebellum initiates motor commands.
D. The cerebellum has no role in balance.
Correct Answer: B
Rationale: The anterior lobe of the cerebellum receives information from the
body trunk (proprioceptive input) .
8. Which of the following is most likely a symptom of ALS?
A. Impaired ability to swallow
B. Decreased sensation in the hands
