Module 5 Psychology 101 Questions
– 100% Correct, Expert Verified
Answers with A+ Grade Assurance
refractory period ANSW ✔✔ a period of inactivity after a neuron has fired
threshold ANSW ✔✔ the level of stimulation required to trigger a neural impulse.
all-or-none response ANSW ✔✔ a neuron's reaction of either firing (with a full-strength
response) or not firing.
biological perspective ANSW ✔✔ concerned with the links between biology and behavior.
Includes psychologists working in neuroscience, behavior genetics, and evolutionary
psychology. (behavioral neuroscientists, neuropsychologists, behavior geneticists,
physiological psychologists, biopsychologists)
neuron ANSW ✔✔ a nerve cell; the basic building block of the nervous system
dendrites ANSW ✔✔ a neuron's bushy, branching extensions that receive messages and
conduct impulses toward the cell body
axon ANSW ✔✔ the neuron extension that passes messages through its branches to other
neurons or to muscles or glands
myelin sheath ANSW ✔✔ a fatty tissue layer segmentally encasing the axons of some
neurons; encasing the axons of some neurons; enables vastly greater transmission speed as
neural impulses hop from one node to the next
synapse ANSW ✔✔ the junction between the axon tip of sending neuron and the dendrite
or cell body of the receiving neuron. The tiny gap at this junction is called synaptic gap or
synaptic cleft.
