BIOS 252: EXAM WITH CORRECT
ANSWERS GRADED A+ /PRACTICE
TEST EXAM
1. Abducens Nerve (VI) - ANSWER-Lateral eye movement (motor)
2. Accessory Nerve (XI) - ANSWER-swallowing, head, neck, and shoulder
movements (motor)
3. Anterior Horn - ANSWER-Somatic motor neurons whose axons exit the
cord via ventral roots
4. Arachnoid Mater - ANSWER-Middle layer of the meninges
5. Ascending Pathway of spinal cord - ANSWER-Carries signals to the
brain
6. Brainstem - ANSWER-The oldest part and central core of the brain,
responsible for automatic survival functions.
7. Cerebellum - ANSWER-A large structure of the hindbrain that controls
fine motor skills. (Balance and coordination)
8. Cerebrum - ANSWER-Largest part of the brain; responsible for
voluntary muscular activity, vision, speech, taste, hearing, thought,
and memory.
, 9. Corpus Callosum - ANSWER-A thick band of axons that connects the
two cerebral hemispheres and acts as a communication link between
them.
10. Damage of what cranial nerve will effect digestion, urination,
and defecation? - ANSWER-Vagus Nerve (X)
11. Define the term spinal reflex, explain organization of a simple
stretch reflex, and use patella reflex as an example. - ANSWER-Spinal
reflex is an involuntary reflex that occurs within the spinal cord.
Stretch reflex: when a muscle is stretched, it "fights back" and
contracts. (Monosynaptic: One synapse between the afferent and
efferent neurons)
12. Descending Pathway of spinal cord - ANSWER-Carries signals to
and from the brain
13. Divisions of Autonomic Nervous System - ANSWER-Sympathetic
and parasympathetic
14. Dorsal Root Ganglion - ANSWER-A nodule on a dorsal root that
contains cell bodies of afferent spinal nerve neurons
15. Dura Mater - ANSWER-Outermost layer of the meninges
16. Explain language: include description of two major languages of
the brain and where they're located. What do they accomplish? -
ANSWER-The two major language centers of the brain are the Broca's
area and Wernicke's area. Broca's area is located in the left
hemisphere of the frontal lobe and controls speech production.
Wernicke's area is also located in the left hemisphere, but on the
posterior section of the superior temporal gyrus of the brain.
Wernicke's area works to comprehend speech.
