Question 2

Parts of the neuron

Answer 2

Cell body 
Axon 
Myelin 
Terminal buttons 
Synapse
Neurotransmitter fluid 
Dendrite

Question 3

Cell body

Answer 3

Main part of the neuron. Starts or strengthens the electrical impulses
(Torso)

Question 4

Axon

Answer 4

Arm-like structure extending away from cell body (right arm)

Question 5

Myelin

Answer 5

MS- Disorder

Question 6

Terminal buttons

Answer 6

Fluid filled sacs at the end of the axon, contains brain chemicals

Question 7

Synapse

Answer 7

The gap between 2 neurons

Question 8

Neurotransmitter fluid

Answer 8

Brain chemicals, passes the “message” to the next neuron

Change chemical=change behavior

Question 9

Dendrite

Answer 9

Tree ranch structure DETECTS incoming chemical message (left arm)
