*sends, integrates, and transmits information
2
Q

3
Q
soma/cell body
A

4
Q
axon
A
extension of neuron
*carries the message away from soma and towards the end
5
Q
myelin sheath
A
fatty tissue that covers some neurons
*insulates and speeds up impulses
6
Q
Schwann cells
A
cells that make sure the myelin sheath is healthy
7
Q
nodes of ranvier
A
the tiny gaps within the myelin
*helps speed impulses
8
Q
axon terminal
A
end point of neuron
*pass the message through neurotransmitters, neurotransmitters are stored here
9
Q
synapse
A
junction where information is transmitted
10
Q
glial cells
A
provide support to keep the neuron healthy
11
Q
