Vertebrate nervous systems have central and peripheral components

Vertebrate nervous systems have central and peripheral components. Central nervous system (CNS). Brain and spinal cord. Both contain fluid-filled spaces which contain cerebrospinal fluid (CSF). The central canal of the spinal cord is continuous with the ventricles of the brain.

1QQ# 13 for 10:30

1QQ# 13 for 10:30. Why is action potential conduction velocity slower in a non-myelinated axon compared to a myelinated axon? In what ways do voltage-gated Na+ channels differ from voltage-gated K+ channels?. 1QQ# 13 for 11:30.
