BIOD 152 EXAM 2 WITH CORRECT
ANSWERS 2025
This is the most superficial layer of the brain meninges. correct
answers >> Dura mater (menix)
The ______ fissure separates the cerebrum from the cerebellum
correct answers >> Transverse
What is the purpose of the blood-brain barrier? Describe its
maintenance from a cellular level. correct 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.

A. Maintain homeostasis
B. Controls the pituitary gland
C. Links the nervous and endocrine systems

C. Occipital lobe
D. Parietal lobe
E. Primary sensory cortex correct answers >> B. Wernicke's
area
Describe how memories are stored and retrieved in the brain.
Include a specific brain region. correct answers >> Memories
are not stored in one specific area within the brain but instead are
