,BIOS 252 Exam 2 Anatomy & Physiology II I Questions And Answers
2026/2027 Chamberlain
1.** The brain and spinal cord together make up which division of the
nervous system?
A) Peripheral nervous system
B) Central nervous system
C) Autonomic nervous system
D) Somatic nervous system
**Correct Answer:** B) Central nervous system
**Rationale:** The central nervous system (CNS) consists of the brain and
spinal cord. The peripheral nervous system (PNS) (A) consists of all nervous
tissue outside the CNS. The autonomic nervous system (C) and somatic
nervous system (D) are divisions of the PNS.
**2.** Which of the following is the largest part of the brain?
A) Cerebellum
B) Brainstem
C) Cerebrum
D) Diencephalon
**Correct Answer:** C) Cerebrum
**Rationale:** The cerebrum is the largest part of the brain, responsible for
higher cognitive functions, voluntary movement, and sensory processing.
,The cerebellum (A) is the second largest part; the brainstem (B) and
diencephalon (D) are smaller structures.
**3.** The longitudinal fissure divides the brain into which two halves?
A) Anterior and posterior
B) Superior and inferior
C) Right and left cerebral hemispheres
D) Frontal and occipital lobes
**Correct Answer:** C) Right and left cerebral hemispheres
**Rationale:** The longitudinal fissure is a deep groove that divides the
cerebrum into right and left cerebral hemispheres. The central sulcus divides
the frontal and parietal lobes; the lateral fissure separates the temporal lobe.
**4.** The corpus callosum is a band of white matter that:
A) Connects the two cerebral hemispheres
B) Connects the brain to the spinal cord
C) Separates the frontal and parietal lobes
D) Connects the cerebellum to the brainstem
**Correct Answer:** A) Connects the two cerebral hemispheres
**Rationale:** The corpus callosum is a large band of white matter
(commissural fibers) that connects the right and left cerebral hemispheres,
allowing communication between them. The brainstem (B) connects the
brain to the spinal cord; the central sulcus (C) separates the frontal and
, parietal lobes; the cerebellar peduncles (D) connect the cerebellum to the
brainstem.
**5.** Which of the following is a function of the frontal lobe?
A) Vision
B) Hearing
C) Voluntary motor control and higher cognitive functions
D) Sensation of touch and pain
**Correct Answer:** C) Voluntary motor control and higher cognitive
functions
**Rationale:** The frontal lobe is responsible for voluntary motor control
(primary motor cortex), higher cognitive functions (prefrontal cortex), and
speech production (Broca's area). Vision (A) is a function of the occipital lobe;
hearing (B) is a function of the temporal lobe; sensation of touch and pain
(D) is a function of the parietal lobe.
**6.** The primary visual cortex is located in which lobe of the brain?
A) Frontal lobe
B) Parietal lobe
C) Temporal lobe
D) Occipital lobe
**Correct Answer:** D) Occipital lobe
