•Isolation of neurons
Action potential occurs at successive nodes along the length of the stimulated axon
The region the brain that is involved in conscious thoughts and intellectual functions as well as processing somatic sensory and motor information
Oversees the postural muscles of the body and making rapid adjustments to maintain balance and equilibrium (coordination)

Nodes of Ranvier
The gaps between Schwann Cells are found at regular intervals in peripheral system neurons called______
The brain dysfunction where blood supply to a region ( or regions) of the brain is blocked and vital brain tissue dies, as by a blood clot of rupture blood vessel is called
One of the last CNS areas to mature, which contains the temperature regulating center and accounts for why premature infants have difficulty controlling body heat loss
What is the correct sequence of events that follow a threshold potential:
1. The membrane becomes depolarized
2.Sodium channels open and sodium ions diffuse inward
3. The membrane becomes Repolorized
4.Active transports move sodium ions out of the cell and potassium ions into the cell
5. Potassium channels open and the potassium ions diffuse outward
