Unit 3 Biological Bases of Behavior

Question 1

Neuron

Answer 1

Everything that you are made of sends signals; basic block of the Nervous system

Question 2

Soma/cell body

Answer 2

Holds nucleus/chromosomes

Question 3

Dendrites

Answer 3

send and receive messages conducting impulses from the soma

Question 4

Axon

Answer 4

Long fiber that passes messages to other neuron’s information travels along with an electrical charge or better known as the AP.

Question 5

Myelin sheath

Answer 5

A fatty covering of the axons that increase communication

Question 6

Terminal buttons

Answer 6

Tiny bubble structures at the end of the axon ( ex:Airplane end calling Uber)

Question 7

Synaptic vesicles

Answer 7

Small containers holding the neurotransmitters connected to the presynaptic membrane, pushing out the neurotransmitter into the synapse.

Question 8

Resting potential

Answer 8

Electrical charge and can be fired at any moment (-70mv).

Question 9

Action potential

Answer 9

Nerve impulse caused by a reversal of a electrical charge across the axon (- to +)

Question 10

Threshold

Answer 10

Barrier needs a certain amount to come through to pass through and once it does it can not go back.

Question 11

Synapse

Answer 11

A communication link between neurons happens by the synaptic gap/cleft and because between a neuron and dendrites of another neuron.

Question 12

All-or-none response

Answer 12

Action potential that goes full force or Nothing must cross the threshold

Question 13

Refractory period

Answer 13

A certain time frame when the neuron can’t reach it’s potential
