BIOS 252: EXAM WITH CORRECT -SOLUTIONS
GRADED A+ /PRACTICE TEST EXAM
1. Arachnoid Mater - -ANS☑️☑️--Middle layer of the meninges
2. Ascending Pathway of spinal cord - -ANS☑️☑️--Carries signals to the brain
3. Brainstem - -ANS☑️☑️--The oldest part and central core of the brain,
responsible for automatic survival functions.
4. Cerebellum - -ANS☑️☑️--A large structure of the hindbrain that controls
fine motor skills. (Balance and coordination)
5. Cerebrum - -ANS☑️☑️--Largest part of the brain; responsible for voluntary
muscular activity, vision, speech, taste, hearing, thought, and memory.
6. Abducens Nerve (VI) - -ANS☑️☑️--Lateral eye movement (motor)
7. Accessory Nerve (XI) - -ANS☑️☑️--swallowing, head, neck, and shoulder
movements (motor)
8. Anterior Horn - -ANS☑️☑️--Somatic motor neurons whose axons exit the
cord via ventral roots
, 9. Corpus Callosum - -ANS☑️☑️--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? - -ANS☑️☑️--Vagus Nerve (X)
11. Define the term spinal reflex, explain organization of a simple stretch reflex,
and use patella reflex as an example. - -ANS☑️☑️--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 - -ANS☑️☑️--Carries signals to and from
the brain
13. Divisions of Autonomic Nervous System - -ANS☑️☑️--Sympathetic and
parasympathetic
14. Dorsal Root Ganglion - -ANS☑️☑️--A nodule on a dorsal root that contains
cell bodies of afferent spinal nerve neurons
15. Dura Mater - -ANS☑️☑️--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? - -ANS☑️☑️--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
