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.
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. Relays sensory impulses to the cerebrum - CORRECT-
ANSWERS>>>>>D
What is the largest portion of the brain?
A. Cerebellum
B. Cerebrum
C. Corpus collosum
D. Cingulate gyrus - CORRECT-ANSWERS>>>>>B. Cerebrum
This region of the brain acts to coordinate multiple sources of
sensory information:
A. Primary sensory cortex
B. Primary motor cortex
C. Association area
D. Precentral gyrus
E. Postcentral gyrus - CORRECT-ANSWERS>>>>>C. Association area
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. Wernicke's area
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 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
emo!onally charged events result in our most vivid memories.
Which statement is false concerning the brainstem?
A. The medulla portion of the brainstem continuous with the
spinal cord.
B. The medulla contains reflex centers to regulate
vasoconstriction.
C. The midbrain contains the superior and inferior colliculi.
D. The midbrain helps to regulate breathing. - CORRECT-
ANSWERS>>>>>D.
