, Neuroanatomy Exam Bank 2026/2027: 100 MCQs with Answers &
Explanations
SECTION A: MENINGES AND GROSS BRAIN STRUCTURE
Question 1
Which meningeal layer is directly adhered to the surface of the brain and follows its
convolutions into the sulci?
A. Dura mater
B. Arachnoid mater
C. Pia mater
D. Subarachnoid layer
Answer: C
Explanation: The pia mater is the innermost meningeal layer that is tightly attached to the brain
surface. It closely follows the contours of the cerebral cortex, dipping into the sulci and covering
the gyri. The dura mater is the outermost tough layer, while the arachnoid mater is the middle
layer separated from the pia by the subarachnoid space.
Question 2
The structure that separates the right and left cerebral hemispheres is the:
A. Transverse fissure
B. Central sulcus
C. Median longitudinal fissure
D. Lateral sulcus
Answer: C
,Explanation: The median longitudinal fissure is the deep groove that separates the two cerebral
hemispheres. The central sulcus separates the frontal and parietal lobes, while the lateral sulcus
separates the temporal lobe from the frontal and parietal lobes.
Question 3
Which of the following accurately describes the cellular composition and function of the blood-
brain barrier?
A. Formed by tight junctions between neurons and microglia, preventing toxin entry
B. Composed of fenestrated capillaries allowing free passage of all blood components
C. Established by endothelial cells with tight junctions supported by astrocytic processes,
restricting entry of most substances
D. Maintained exclusively by oligodendrocytes to regulate cerebrospinal fluid composition
Answer: C
Explanation: The blood-brain barrier is formed by brain capillary endothelial cells that are
connected by tight junctions, creating a selective permeability barrier. Astrocytes (specifically,
their end-feet processes) play a crucial supportive role in inducing and maintaining these tight
junctions. This barrier restricts the passage of most substances, maintaining the stable chemical
environment essential for proper neuronal function. It allows passage of lipid-soluble substances
and small molecules while restricting larger molecules and pathogens.
Question 4
All of the following are established functions of the hypothalamus EXCEPT:
A. Homeostatic regulation of body temperature, hunger, and thirst
B. Control of the pituitary gland via releasing and inhibiting hormones
C. Integration of the nervous and endocrine systems
D. Relay of sensory impulses to the cerebral cortex
Answer: D
, Explanation: The hypothalamus is a critical regulatory center with multiple functions including
maintaining homeostasis, controlling the pituitary gland, and linking the nervous and endocrine
systems. However, relaying sensory impulses to the cerebrum is primarily a function of the
thalamus, which serves as the major sensory relay station for most sensory pathways (except
olfaction).
Question 5
What is the largest portion of the human brain, constituting approximately 83% of its total mass?
A. Cerebellum
B. Corpus callosum
C. Cerebrum
D. Diencephalon
Answer: C
Explanation: The cerebrum is the largest portion of the brain, comprising about 83% of total
brain mass. It is divided into two cerebral hemispheres and is responsible for higher cognitive
functions, sensory processing, and voluntary motor control. The cerebellum accounts for
approximately 10% of brain volume but contains more than half of all neurons.
Question 6
This region of the cerebral cortex is responsible for integrating multiple sources of sensory
information to form a comprehensive understanding of the environment:
A. Primary sensory cortex
B. Primary motor cortex
C. Association areas
D. Precentral gyrus
Answer: C
