Unit 2 AP Psychology Exam Questions
With Correct Answers
biological psychologists - CORRECT ANSWER✔✔-the scientific study of
| | | | | | | |
the links between biological and psychological processes.
| | | | | |
neuron - CORRECT ANSWER✔✔-a nerve cell; the basic building block of
| | | | | | | | | | |
the nervous system.
| |
dendrites - CORRECT ANSWER✔✔-the bushy, branching extensions of a
| | | | | | | | |
neuron that receive messages and conduct impulses toward the cell
| | | | | | | | | |
body.
axon - CORRECT ANSWER✔✔-the neuron extension that passes and
| | | | | | | | |
electrical messages through its branches to other neurons or to muscles
| | | | | | | | | |
or glands.
| |
myelin sheath - CORRECT ANSWER✔✔-a layer of fatty tissue
| | | | | | | | |
segmentally encasing the fibers of many neurons; enables vastly greater
| | | | | | | | |
transmission speed of neural impulses as the impulse hops from one
| | | | | | | | | | | |
node to the next.
| | |
, action potential - CORRECT ANSWER✔✔-a neural impulse; a brief
| | | | | | | | |
electrical charge that travels down an axon.
| | | | | |
refractory period - CORRECT ANSWER✔✔-a period of inactivity after a
| | | | | | | | | |
neuron has fired. | |
threshold - CORRECT ANSWER✔✔-the level of stimulation required to
| | | | | | | | |
trigger a neural impulse.
| | |
all-or-nothing response - CORRECT ANSWER✔✔-a neuron's reaction of
| | | | | | | |
either firing or not firing.
| | | |
synapse - CORRECT ANSWER✔✔-the junction between the axon tip of
| | | | | | | | | |
the sending neuron and the dendrite or cell body of the receiving
| | | | | | | | | | | |
neuron. The tiny gap at this junction is called the synaptic gap or
| | | | | | | | | | | | |
synaptic cleft. |
neurotransmitters - CORRECT ANSWER✔✔-chemical messengers that | | | | | |
cross the synaptic gaps between neurons. When released by the
| | | | | | | | | |
sending neuron, they travel across the synapse and bind to receptor
| | | | | | | | | | |
sites on the receiving neuron, thereby influencing whether that neuron
| | | | | | | | | |
will generate a neural impulse.
