BIOD 152 Essential Human Anatomy & Physiology II - Module 2 Exam
2026/2027 UPDATE
1. Which lobe of the cerebrum is primarily responsible for processing visual
information?
A. Occipital Lobe
B. Temporal Lobe
C. Frontal Lobe
D. Parietal Lobe
Answer: A
Rationale: The occipital lobe contains the primary visual cortex and is the main center for
visual processing.
2. The primary motor cortex is located in which specific structure of the brain?
A. Postcentral gyrus
B. Corpus callosum
C. Precentral gyrus
D. Cerebellum
Answer: C
Rationale: The precentral gyrus of the frontal lobe contains the primary motor cortex,
which controls voluntary muscle movements.
,3. Which part of the diencephalon acts as a relay station for nearly all sensory
impulses traveling to the cerebral cortex?
A. Thalamus
B. Epithalamus
C. Hypothalamus
D. Pineal gland
Answer: A
Rationale: The thalamus is the main relay station for sensory information, sorting and
directing it to the appropriate areas of the cerebrum.
4. Regulation of body temperature, hunger, and thirst is primarily controlled by
the:
A. Thalamus
B. Pons
C. Medulla oblongata
D. Hypothalamus
Answer: D
Rationale: The hypothalamus is the chief integration center for the autonomic nervous
system and regulates homeostasis, including temperature and fluid balance.
5. Damage to the cerebellum would most likely result in:
A. Loss of hearing
B. Inability to form new memories
C. Loss of muscular coordination and balance
D. Visual hallucinations
Answer: C
Rationale: The cerebellum is responsible for coordinating skilled skeletal muscle
movements and maintaining posture and balance.
, 6. Which structure in the brainstem contains vital centers for regulating heart
rate and breathing?
A. Midbrain
B. Pons
C. Thalamus
D. Medulla oblongata
Answer: D
Rationale: The medulla oblongata contains the cardiovascular and respiratory centers that
control heart rate and the basic rhythm of breathing.
7. The bridge-like structure that connects the left and right cerebral
hemispheres is the:
A. Septum pellucidum
B. Corpus callosum
C. Internal capsule
D. Fornix
Answer: B
Rationale: The corpus callosum is a large tract of white matter that allows communication
between the two cerebral hemispheres.
8. Which cranial nerve is responsible for the sense of smell?
A. CN II (Optic)
B. CN I (Olfactory)
C. CN III (Oculomotor)
D. CN V (Trigeminal)
Answer: B
Rationale: Cranial Nerve I, the Olfactory nerve, is purely sensory and carries impulses
related to smell.
