What makes the myeline sheath
Schwann cells
The sheaths how are they structured
They are fatty layers that warp around the axon
When sheaths are damaged what can happen to the impulse
It will slow down
What does the myelin sheath do
Speed up conduction
What are the gaps in between the sheaths
Node of ranvier
What is an internode
The myelinated spaces bewteen gaps
Functions of the myelin sheath
protect the nerve fibre
Helps the nervous system to communicate
Generates conductions
What do the nodes of ranvier do
Travel impulses down for action potential from one node to another r
What is saltatorry conduction
Impulses jumping from node to node
Are the myeline sheaths flat
Yes
