Parts of a Neuron

Question 1

1. Dendrites
   -structure vs function (2)

Answer 1

-numerous, large surface area to receive incoming signals from other neurons, conducts impulses to cell body

Question 2

2. Cell body
   -recieves what from dendrite and does what with it

Answer 2

-recieves the iumpulse from dendrite and sends it to axon like a bridge

Question 3

3. Axon
   -where does it send the nerve impulses

Answer 3

-other neurons or effectors

Question 4

Myelin Sheath
-what is it

Answer 4

a thick insulating material that makes up the schwann cell

Question 5

Schwan Cell
-what is it

Answer 5

a type of gilial cell that wraps around the axon

Question 6

Nodes of Ranvier
-what is it

Answer 6

spaces between the Schwann cells

Question 7

Neurilemma
-what nervous system contains it
-what does it surround and its function

Answer 7

-PNS
-wrapped around the axon and regenerates damaged axon

Question 8

4. Axon Terminal
   -where is it
   -what do they store, what is synapse

Answer 8

-end of axon
-neurutransmittors which are chemicals that will be released to carry the message across the SYNAPSE (space between) to a dendrite of another neuron or effector
