The ______ are the receiving end of a neuron, while the _____ conducts nerve impulses away
from the cell body - correct answer-dendrites; axon
list the phases of an action potential - correct answer-1. resting potential, 2. depolarization, 3.
depolarization, 4. afterpolarization
true or false: if false explain why the statement is false: The central nervous system cosists of
the brain and spinal cord - correct answer-true
Match the following lobes of the brain with the correct function
A. temporal
B. Frontal
C. Parietal
D. Occipital
1. Interprets visual input
2. contains sensory areas for hearing and smelling
3. controls higher level of executive function
4. receives sensory information from body receptor - correct answer-A. Controls sensory areas
for hearing and smelling
B. Controls higher level executive function
C. Receives sensory information from body receptors
D. Interprets visual input
Which of the following structure of the spinal cord contains the cell bodies of afferent neurons?
A. Anterior horn
B. Dorsal root ganglion
C. Ventral root
, D. Gray commissure - correct answer-B. Dorsal root ganglion
Describe the function the sympathetic nervous system when a threat is present - correct
answer-the sympathetic system is especially important during emergency situations and is
associated with the "fight or flight" response. When in immediate danger, active muscles
require a steady, increased supply of glucose and oxygen for muscular contraction. the
sympathetic system accelerates the heartbeat, dilates the bronchi, and increases the breathing
rate. the impacts of the sympathetic system supply the increased need for oxygen throughout
the body. at the same time, the sympathetic system causes the liver to deliver more glucose for
the body's increased metabolic needs. sympathetic activation inhibits the digestive tract since
digestion is not an immediate necessity when in danger or under attack
true or false: if false explain why the statement is false. visual information form the left side will
eventually be interpreted by the left side of the brain - correct answer-false: sensory
information gathered from the left side of the body (bilateral left visual fields) will eventually be
interpreted in the right side of the brain
describe the process by which the vestibular system processes equilibrium and balance
information - correct answer-each semicircular canal contains equilibrium receptors, which
cause action potentials in response to different types of motion (head movements or rotation).
the action potentials are sent through the vestibular portion of CN VIII. the semicircular canals
contribute in this way to the body's vestibular sense (balance and upright orientation)
true or false: if false explain why the statement is false: the following is the order of the flow of
information through the olfactory system. olfactory receptor, olfactory nerves, olfactory bulbs,
olfactory tracts, temporal lobes - correct answer-true
the two upper receiving chambers of the heart are called the _______, while the two lower
pumping chambers are called the ______ - correct answer-atria, ventricles
which vessels contain the largest amount of blood in the cardiovascular system? explain -
correct answer-veins have compliance, which means stretch with little recoil. because of their
compliance, veins have the largest amount of blood in the cardiovascular system
from the cell body - correct answer-dendrites; axon
