1. Which lobe of the brain is primarily responsible for voluntary
motor function?
A) Frontal lobe
B) Parietal lobe
C) Temporal lobe
D) Occipital lobe
Correct Answer: A
Rationale: The primary motor cortex (precentral gyrus) is located
in the frontal lobe. This area controls voluntary fine motor
movements. The parietal lobe (B) processes sensory information.
1
,The temporal lobe (C) is involved in hearing and memory. The
occipital lobe (D) processes vision.
2. The Broca’s area is located in which hemisphere and lobe?
A) Left frontal lobe
B) Right frontal lobe
C) Left temporal lobe
D) Right parietal lobe
Correct Answer: A
Rationale: Broca’s area (Brodmann areas 44 and 45) is typically
located in the left frontal lobe. It is responsible for expressive
language (speech production). A lesion here causes non-fluent
(Broca’s) aphasia. The right frontal lobe (B) is not associated with
language in most right-handed individuals. The left temporal
lobe (C) houses Wernicke’s area (receptive language). The right
parietal lobe (D) is involved in spatial awareness.

,3. Which structure connects the left and right cerebral
hemispheres?
A) Corpus callosum
B) Fornix
C) Anterior commissure
D) Septum pellucidum
Correct Answer: A
Rationale: The corpus callosum is the largest white matter tract
connecting the two cerebral hemispheres, allowing
interhemispheric communication. The fornix (B) connects the
hippocampus to the mammillary bodies. The anterior commissure
(C) also connects hemispheres but is much smaller. The septum
pellucidum (D) is a membrane separating the lateral ventricles,
not a connecting tract.
4. The primary visual cortex (V1) is located in which lobe?
A) Frontal
3
, B) Temporal
C) Parietal
D) Occipital
Correct Answer: D
Rationale: The primary visual cortex (V1, striate cortex) is located
in the occipital lobe along the calcarine sulcus. It receives and
processes visual input. The frontal lobe (A) controls motor
function. The temporal lobe (B) processes auditory information.
The parietal lobe (C) processes somatosensory information.
5. Damage to the Wernicke’s area results in:
A) Fluent aphasia with poor comprehension
B) Non-fluent aphasia with good comprehension
C) Apraxia
D) Agnosia
Correct Answer: A
Rationale: Wernicke’s area (superior temporal gyrus) is
