HUMAN ANATOMY & PHYSIOLOGY 2 CHAPTER 10 QUIZZES
ALL ANSWERED PERFECTLY!!
Ganglia
Answers :Clusters of nerve cell bodies, part of PNS. Carry nerve signals to and
from the CNS.
Repolorized


Answers :a stage of an action potential in which the cell experiences a decrease of
voltage due to the efflux of potassium (K+) ions along its electrochemical gradient.
This phase occurs after the cell reaches its highest voltage from depolarization.
Dendrite


Answers :Branched process, serves as the receptor surface of a neuron.
threshold


Answers :Level of potential at which an action potential is triggered in a neuron or
a muscle fiber. 0mV
Facilitated


Answers :Repeated stimulation of an excitatory presynaptic neuron, may cause it
to release more neurotransmitters in response to one impulse, increasing the
likelihood that a postsynaptic neuron will reach threshold.
Beta Endorphine


Answers :Substance produced in brain that blocks sensation of pain.
Epinephrine

, Answers :hormone that causes blood vessels to narrow and the blood pressure to
increase.
Convergence


Answers :Two or more presynaptic neurons forming synpses with the same
postsynaptic neuron.
hyperpolorized


Answers :polorization more negative that the resting potential potassium continues
to flow out of the cell- leaving it more negative. charge from -70mV- -90mV
depolorized


Answers :makes it positive- creates from positive threshold
divergence


Answers :a single neuron having synapses with two or more postsynaptic cells.
reuptake


Answers :a neurotransmitters reabsorption be the sending of neurons.
Schwann Cell


Answers :type of neuroglia that surrounds an axon of a peripheral neuron, forming
the neurolemma and myelin.
Serotonin


Answers :-primarily inhibitory
-CNS
