Chapter 2 - Neuroscience And Behavior

Front 1

Who invented psychology?

Back 1

Franz Gall

Front 2

Biological Psychologists

Back 2

a branch of psychology concerned with the links between biology and behavior

Front 3

Neuron

Back 3

a nerve cell. basic building block of the nervous system

Front 4

Dendrite

Back 4

branching extensions of a neuron that receive messages and conduct impulses towards the cell body

Front 5

Axon

Back 5

the extension of a neuron, ending in branching terminal fibers that send messages pass to other neurons tor to muscles and glands

Front 6

Action Potential

Back 6

a neural impulse, a brief electrical charge that travels down an axon

Front 7

Threshold

Back 7

the level of stimulation needed to trigger a neural response

Front 8

All or None Response

Back 8

Neurons either fire or don't (like a gun, you pull the trigger or you don't)

Front 9

Myelin Sheath

Back 9

covers the axon of some neurons and helps speed neural impulses

Front 10

Who coined the name synapse?

Back 10

Charles Sherrington

Front 11

Synapse

Back 11

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 cleft

Front 12

Neurotransmitters

Back 12

chemical messengers that travel along the synapse between neurons and it will influence the neural impulse

Front 13

Reuptake

Back 13

process when the sending neuron reabsorbs excess neurotransmitter molecules
