Q

What is the relationship between Schwann cells and axons?

A

The Schwann cells make up the myelin sheath, which insulates the axon so AP transmission is faster.

Q

What is the difference between the role of dendrites and axons?

A

dendrites receive AP impulses, while axons transmit AP impulses
