1. the neuron pictured below, is best described as: multipolar
2. true or false, explain why the state is false : Bipolar neurons have a central
cell body with two extensions: true
3. List the phases of an action potential in order: 1. resting potential
2. depolarization
3.repolarizarion
4.resting condition
4. true or false , if false explain why the statement is false: the central nervous
system consists of the brain and spinal cord: true
5. 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: de-
privation, 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
6. This part of a reflex is inside the CNS, made up of one or more synapses.: -
integration center
7. 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
8. which of the following structures of the spinal cord contains the cell bodies
of afferent neurons: dorsal root ganglion
9. 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-CON-
TRACTION OF 2 MUSCLES
10. Label the nerves (A-C) in the figure below:
A: _________________
B: _________________
C: _________________: a. lateral femoral cutaneous
b- femoral nerve
c. saphenous

11. which of the following is most likely a symptom of ASL: impaired ability to
swallow
12. 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
13. which of the following visual conditions is caused by damage to the
abducens nerve?: diplopia
14. 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
15. a pt is unable to extend his left wrist or fingers. what never is most likely
damaged ?: radial nerve
16. explain the main steps in the process of hearing: 1.) sound waves are
funneled through the external auditory Canal which causes the eardrum to vibrate
2. the vibrations go into the ossicles and push against the fluids inside the cochlear
duct. the movement of the fluid causes the stereocilla in the organ of court to move
as well.the neurons are stimulated to send impulses through the cochlear nerve to
the primary auditory cortex of the temp lobe
17. which cell serves as stem cells in the gustatory system that divide and
differentiate into new supporting cells then form new gustatory cells: basal
cells
18. fill in the blanks: the two upper receiving chambers of the heartier called
the ___, while the two lower pumping chambers are called the: ratio , ventricles
19. which of the following is not a type of granulocyte: b-cells
20. describe how memories are stored and retrieved in the brain. include a spe-
cific brain region.: the amygala and the involvement of the limbic system explains
why emotionally charged events and occurrences cause our most vivid memories.
the limbic system communicates with all the sensory areas and is responsible for
the ability of a sensory stimulus to create a complex memory
21. a pt had a CVA in the area indicated by the red x in the figure, below.
What type of blindness is the pt most likely to incur: bilateral left field blindness
because the injury or the damage occurs in the right optic tract
22. match the numbers(1-5) in the figure below with the correct terms (a-h)
note all will not be used: 1.)facial nerve
2.)malleus
