motor neuron

Question 1

Neuroplasticity

Answer 1

The brain reorganizes with new pathways after damage

Question 2

Cell Body

Answer 2

SOMA; powerhouse of neurons

Question 3

Dendrites

Answer 3

gets information from cells and transfers it to the cell body.

Question 4

Axon

Answer 4

pass message away from cell body to muscles and glands

Question 5

Neural Impulse

Answer 5

action potential; eclectic signal travel down axon

Question 6

Meylin Sheath

Answer 6

covers axon to help with speed

Question 7

Terminal Branches of Axon

Answer 7

give information to other cells

Question 8

Glial Cells

Answer 8

cell in nervous system that protects neurons. Also help with thinking and learning.

Question 9

Threshold

Answer 9

trigger neural impulse with level of stimulation

Question 10

Action Potential

Answer 10

chemical impulse that travels down axon

Question 11

All or Nothing Responce

Answer 11

neuron reacts like a gun

Question 12

Refactory Period

Answer 12

time after impulse; action potential happens after pause

Question 13

Synapse

Answer 13

send message; axon tip and the dendrites/cell body receive messages

Question 14

Neurotransmitter

Answer 14

chemical messenger that travels across synapses

Question 15

Endorphines

Answer 15

opiate neurotransmitter, pain control and pleasure

Question 16

Antagonist

Answer 16

Block neurotransmitter, pain control and pleasure

Question 17

Agonist

Answer 17

increase neurotransmitter action
