BIOS 242 WEEK 9 FINAL EXAM STUDY GUIDE
2026 TESTED QUESTIONS ANSWERS GRADED
◉ The primary motor area of the cerebral cortex is located in the:
Answer: a. precentral gyrus.
◉ The degree of muscled stretch is monitored by: Answer: d. muscle
spindles.
◉ The function of tendon organs is to monitor the: Answer: c. force
of muscle contraction.
◉ A stimulus that elicits a receptor potential causes: Answer: a.
direct release of neurotransmitter via exocytosis from synaptic
vesicles.
◉ A generator potential would be produced by ALL of the following
EXCEPT: Answer: e. taste buds.
◉ ALL of the following would be sensed by mechanoreceptors
EXCEPT: Answer: e. light.
, ◉ During a maintained, constant stimulus, a generator potential or a
receptor potential decreases in amplitude in a phenomenon known
as: Answer: a. adaptation.
◉ Intrafusal muscle fibers contract when stimulated by: Answer: c.
gamma motor neurons.
◉ Third-order sensory neurons in the posterior column-medial
lemniscus pathway extend from the: Answer: e. thalamus to the
somatosensory area of the cerebral cortex.
◉ The cell bodies of first-order neurons in the posterior column-
medial lemniscus pathway to the cortex are located in the: Answer:
a. posterior root ganglia of spinal nerves.
◉ The reason visceral pain is referred to surface structures is that:
Answer: e. sensory neurons for both visceral pain and surface
structures enter the same segment of the spinal cord, and surface
sensations are better localized by the brain.
◉ The stage of deep sleep dominated by delta waves on an EEG, and
during which events such as bed-wetting and sleepwalking occur is:
Answer: e. Stage 4 NREM sleep.
