Q

What type of cell is this?

A

Ependymal cell

Q

What is myelination?

A

A lipid/fatty coating that increases the speed of conduction

Q

What is the un-labeled part?

A

Nodes of Ranvier

Q

What is a compound nerve action potential?

A

When all of the axions are firing together

Q

What is a conduction velocity test?

A

A test meant to test if there are differences in the nerves. You are testing for spinal nerve issues/damage.
