Study Slideshow

this part of a neuron receives messages

dendrites

5

this is also called the cell body

soma

10

this is the part of the neuron that the signal travels down

axon

15

this is the part of the dendrite that receives signals

receptor sites

20

this is the fatty substance around the axon that protects it

myelin

25

these create the myelin

Schwann cells

5

these act like cell phone towers allowing the signal to travel more quickly down the axon

Nodes of Ranvier

10

these are where the terminal vesicles are stored

terminal buttons

15

these are sacs filled with neurotransmitters

terminal vesicles

20

electrical signals are turned into chemicals that are passed to the next neuron called

neurotransmitters

25

the space between two neurons (terminal button and dendrites) is called

synapse

5

this is the process by which sodium ions travel into the neuron and potassium flows out

depolarization

10

when a neuron reaches a threshold of depolarization is allows the neuron to fire, the firing of the neuron is called

Action Potential

15

a neuron either fires or it doesn't; this process is called

All-or-None Respose

20

What two things determine the strength of neuron firing?

how many times it fires and how fast it can complete its refractory period

25

this is the process by which unused neurotransmitters are reabsorbed by the original neuron

reuptake

5
