BIOD152 A&P 2-Portage Learning Final
Exam
the neuron pictured below, is best described as
multipolar
true or false, explain why the state is false : Bipolar neurons have a central cell body with two extensions
true
List the phases of an action potential in order
1. resting potential
2. depolarization
3.repolarizarion
4.resting condition
true or false , if false explain why the statement is false: the central nervous system consists of the brain
and spinal cord
true
name and describe what is occurring in the neurocell membrane in section 2 of the diagram. include the
charge of the membrane during this phase
deprivation, sodium gates are opened and the sodium floods into the axon admits the depolarization of
the action potential, causing the charge voltage to go from 0 to +40 mV
This part of a reflex is inside the CNS, made up of one or more synapses.
integration center
match the following lobes of the brain with the correct function
, temporal - contains sensory areas for hearing and smelling
frontal- contain higher levels ex..
pariteal - receives sensory info from body receptors
occipital - interprets visual input
which of the following structures of the spinal cord contains the cell bodies of afferent neurons
dorsal root ganglion
what is true about the flexor withdrawl reflex
A&d (IT DOES NOT INVOLVE INTERNEURONS & THE EFFECT OF THE REFLEX IS TO CREATE A CO-
CONTRACTION OF 2 MUSCLES
Label the nerves (A-C) in the figure below:
A: _________________
B: _________________
C: _________________
a. lateral femoral cutaneous
b- femoral nerve
c. saphenous
which of the following is most likely a symptom of ASL
impaired ability to swallow
describe the function of the parasympathetic nervous system
aka the housekeeper system because it promotes all of the internal responses in the relaxed state.
Parasympathetic stimulation causes the pupil of the eye to get smaller and aids the lenses of the eyes to
focus on close items. it helps with the digestion of food and also helps with the beating of the heart and
slowing it
which of the following visual conditions is caused by damage to the abducens nerve?
diplopia
what is the purpose of the blood brain barrier? describe its maintenance from a cellular level
it is a diffusion barrier that helps in the prevention of unneeded materials that attack the CNS by
keeping the brain and spinal cord away from the general blood bank.It is composed of the gilal cells
astrocytes and its pertinent for regulation to be able to keep a homestatis which aids in protecting the
neurons
