QUESTIONS AND ANSWERS | 100% RATED CORRECT | 100% VERFIED |
ALREADY GRADED A+|GET A+
1. This is the most superficial layer of the brain meninges.: Dura Mater (Menix)
2. This layer of the meninges is tightly attached to the brain.: Pia mater (Menix)
3. The____________fissure separates the right and left cerebral hemispheres-
: Median longitudinal
4. The___________fissure separates the cerebrum from the cerebellum:
Transverse
5. Describe the function of the brain ventricles: Four ventricles in interior of
brain, chambers filled with cerebrospinal fluid - produced there.
Once formed CSF circulates through ventricles & into subarachnoid space bathing
& floating the brain.
6. What is the purpose of the blood-brain-barrier? Describe its maintenance
from a cellular level.: Diffuse & prevent some particles from entering CNS
tissue.
Allowing brain & spinal cord separate from general blood circulation.
7. All of 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: D. Relays sensory impulses to the
cerebrum
8. This ventricle is located anterior to the cerebellum: fourth
9. What is the largest portion of the brain?
A. Cerebellum
B. Cerebrum
C. Corpus collosum
D. Cingulate gyrus: B. Cerebrum
10. 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: C. Association area
11. This region of the brain controls decision making skills: frontal lobe
, 12. 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: B. Wernicke's area
13. A patient is having difficulty producing speech sounds, but other motor
movements are normal. Which area of the brain is most likely damaged?:
Broca's area
14. Describe how memories are stored and retrieved in the brain. Include a
specific brain region.: Stored throughout cerebral hemispheres.
Hippocampus acts as memory center to help with memory storage & retrieval.
Also includes limbic system --> emotionally charged events = most vivid mems 15.
What is muscle tone and how is it maintained?: Muscle tone - degree at which
muscles remain partially contracted while at rest.
Is continuously monitored and maintained by the cerebellum to keep bones/joints
in place.
16. Which statement is false concerning the brainstem?
