Portage Learning Anatomy & Physiology 2: Module
2 Exam Actual Questions And Answers Grade A+.
This layer of the meninges is tightly attached to the brain.
Pia mater (menix)
The _______ fissure separates the right and left cerebral hemispheres.
Median longitudinal
What is the purpose of the blood-brain barrier? Describe its maintenance from a cellular
level.
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:
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?
A. Cerebellum
B. Correct! Cerebrum
, C. Corpus collosum
D. Cingulate gyrus
This region of the brain acts to coordinate multiple sources of sensory information.
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?
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.
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.
