AP Psychology Unit 3 Exam Questions
With Correct Answers
dendrites - CORRECT ANSWER✔✔--input fibers that carry electrical
| | | | | | | |
signals into a neuron from connected cells.
| | | | | |
soma (cell body) - CORRECT ANSWER✔✔--control center of neuron
| | | | | | | |
-integrates inputs from all dendrites | | | |
-determines whether neuron should fire or not | | | | | |
axon - CORRECT ANSWER✔✔--output fiber carries electrical signal from
| | | | | | | | |
a neuron to a neighboring cell.
| | | | |
-neurons have one each | | |
-larger than dendrites
| |
-divide into branches at end called terminals
| | | | | |
myelin sheath - CORRECT ANSWER✔✔--a layer of fatty tissue that
| | | | | | | | | |
covers around the axon
| | |
-enables greater transmission speed of neural impulses as impulses
| | | | | | | | |
jump from node to node
| | | |
-composed of glial cells (glove), support, nourish, protect neurons.
| | | | | | | |
, synapse - CORRECT ANSWER✔✔--the junction between the axon tip
| | | | | | | | |
and the dendrite of the receiving neuron.
| | | | | |
-called the synaptic gap or cleft as well
| | | | | | |
resting state - CORRECT ANSWER✔✔--a neuron has a slightly negative
| | | | | | | | | |
charge
-negative ions mostly inside cell, positive ones outside.
| | | | | | |
level of excitation - CORRECT ANSWER✔✔--level of stimulation needed
| | | | | | | | |
for electrochemical communication to occur.
| | | |
action potential - CORRECT ANSWER✔✔--brief charge that travels down
| | | | | | | |
the axon as it becomes depolarized.
| | | | | |
-travels down to terminal where it causes neuro transmitters that bind
| | | | | | | | | | |
to specific receptor sites on receiving neurons to fire.
| | | | | | | |
refractory phase - CORRECT ANSWER✔✔--return to state of resting
| | | | | | | | |
slightly negative charge (polarization)
| | |
-no amount of stimulation can cause the neurons to fire again in this
| | | | | | | | | | | | |
stage.
-absolute refractory phase is followed by relative refractory phase in
| | | | | | | | | |
which neuron needs more stimulation to fire again.
| | | | | | |
