Module 2 Exam , 2026/2027, Questions with
Verified Answers
This layer of the meninges is tightly attached to the brain. - ANSWERS-Pia
mater (menix)
The _______ fissure separates the right and left cerebral hemispheres. -
ANSWERS-Median longitudinal
What is the purpose of the blood-brain barrier? Describe its maintenance
from a cellular level. - ANSWERS-The blood-brain barrier is a diffusion barrier
which prevents most particles from entering the central nervous system
tissue, keeping the brain and spinal cord separate from general blood
circulation. The blood-brain barrier is formed by the relatively impermeable
brain capillaries, due to the glial cells astrocytes. Maintenance of the blood-
brain-barrier is important to provide a stable chemical environment for the
nervous system.
All the following are functions of the hypothalamus except: - ANSWERS-A.
Maintain homeostasis
B. Controls the pituitary gland
C. Links the nervous and endocrine systems
D. Correct! Relays sensory impulses to the cerebrum
What is the largest portion of the brain? - ANSWERS-A. Cerebellum
B. Correct! Cerebrum
C. Corpus collosum
, D. Cingulate gyrus
This region of the brain acts to coordinate multiple sources of sensory
information. - ANSWERS-A. Primary sensory cortex
B. Primary motor cortex
C. Correct! Association area
D. Precentral gyrus
E. Postcentral gyrus
A patient is having difficulty understanding language but is still able to speak
fluently. The patient's dermatomes are intact. Which area of the brain is most
likely damaged? - ANSWERS-A. Broca's area
B. Correct! Wernicke's area
C. Occipital lobe
D. Parietal lobe
E. Primary sensory cortex
Describe how memories are stored and retrieved in the brain. Include a
specific brain region. - ANSWERS-Memories are not stored in one specific
area within the brain but instead are stored throughout the cerebral
hemispheres. The hippocampus acts as a memory center to help with
memory storage and retrieval. The involvement of the limbic system explains
why emotionally charged events result in our most vivid memories.
Which statement is false concerning the brainstem? - ANSWERS-A. Correct!
The midbrain portion of the brainstem is continuous with the spinal cord.
B. The pons helps to regulate breathing.
C. The midbrain contains the superior and inferior colliculi.
D. The medulla contains reflex centers to regulate vasoconstriction.
