BIO 348 EXAM 2 QUESTIONS WITH COMPLETE
SOLUTIONS
3 types of excitable tissues Correct Answers nervous tissue,
skeletal muscles , and cardiac muscles
absolute refractory Correct Answers is a period of time in
which a second action potential absolutely cannot be initiated,
no matter how large the applied stimulus is
action potential Correct Answers is a sequence of rapidly
occurring events that decrease and eventually reverse the
membrane potential and then restore it to the resting potential
all or none response Correct Answers unlike grade potentials
that get larger with increasing stimulus strength, the action
potential is an all-or-none response
anterior median fissure Correct Answers deep groove on the
anterior side of the spinal cord
aponeurosis Correct Answers extension from a muscle that
forms a broad flat sheet
arachnoid matter Correct Answers which later of meninges is
the middle layer and resembles a "Spiders web"
Autonomic motor neurons Correct Answers regulate visceral
activites by either increasing or decreasing ongoing activities in
their effector tissues
,axon Correct Answers during a nerve impulses, the action
potential is carried away from the nerve cell body by the ?
axon Correct Answers the single long extension from a cell
body that conducts impulses away from the body
axon hillock Correct Answers the initial segment of the axon
where it is attached to the cell body and where the action
potential begins
axon terminals Correct Answers highly branched fine
processes at the end of an axon
basic tasks of the nervous system Correct Answers sensory
receptor, sensory input, integration, motor output, and effector
brain stem Correct Answers in which part of the brain are the
cardiovascular and respiratory centers located
cell body Correct Answers the central part of the neuron that
contains the nucleus and necessary organs
central sulcus Correct Answers is the grand canal
cerebral aqueduct Correct Answers the ____ is a small canal
that allows cerebrospinal fluid to pass the third ventricle to the
fourth
cerebrum Correct Answers which of the following is the largest
part of the brain
, chemoreceptors Correct Answers monitor blood co2 level
cholinergic neurons include Correct Answers 1. all sympathetic
and parasympathetic preganglionic neurons
2. sympathetic postganglionic neurons that innervate most sweat
glands
3. all parasympathetic postganglionic neurons
cistern Correct Answers a receptacle for something
conus medullaris Correct Answers tapered portion at the
bottom of the spinal cord
corpora quadrigemina Correct Answers contains the superior
colliculi which helps with your visual reflex
corpus callosum Correct Answers the ___ is a thick band of
white matter (nerve tracts) that connects the left and right
hemispheres of the cerebrum and permits nerve impulses to
cross from one hemisphere of the cerebrum to the other
corpus callosum Correct Answers white matter; it transfers
information between the two hemispheres' its like a border of
the cerebral cortex from the stuff below
creatin Correct Answers creates short muscle contraction to
happen
