BIO 669 exam 1 with Verified Solutions
damage to Broca's area is most likely to cause Correct Ans-Inability/difficulty in forming
words (expressive aphasia)
the reticular formation is responsible for Correct Ans-Wakefulness and vital reflexes
sympathetic system stimulation causes all of the follwing except Correct Ans-increasing
vasodilation of vascular smooth muscle
demyelinating diseases such as MS and Guillain barre syndrome may not initially damage the
axon but can still result in symptoms and dysregulation because the Correct Ans-the rate of
AP transmission, thus the information is altered
Upon opening, voltage gated Na+ channels will allow ions to flow until: Correct Ans-the
inactivation gates close
which of the following receptor types does not activate G protiens (ie dos not use a second
messenger system) Correct Ans-nicotinic
A stroke in the occipital lobe is most likely to show signs & symptoms affecting the: Correct
Ans-patients vision
, the alpha 1 receptor will, upon binding to its ligand will result in which of the follwing effects
Correct Ans-excitation and vasoconstriction of vascular smooth muscle
which of the following is a correct statement regarding the comparison of the autonomic and
somatic nervous system Correct Ans-they both originate in the CNS and end in the PNS, so
are a part of the peripheral nervous system.
the effect of the sympathetic nervous system activation on metabolism includes all of the
following except Correct Ans-storage of glucose as glycogen is enhanced
if the k+ channels opened and stayed open in an otherwise normal person, what would happen to
the resting membrane potential of -70mV Correct Ans-become more negative until the
membrane potential reached -94mV
the minimum depolarization needed to open voltage-gated Na+ channels and form an action
potential is term Correct Ans-threshhold
Any given spinal nerve arises from (is formed by): Correct Ans-the combination of an
anterior spinal root with a posterior spinal root
vascular smooth muscle is most impacted by what type of receptor( what receptor is most
present) Correct Ans-alpha 1
