NERVES SYSTEM
-
-
-
Autonom Nerves System
The part of the peripheral nervous system that functions as a regulator of unconscious body functions, for example blood flow and heart rate

Mechanism Nerves
- When the Action Potential reaches the axon terminal, DEPOLARIZATION will occur and Na+ channels will open, Na+ ions will further depolarize the presynaptic membrane. In a more positive direction until the peak of P.A +3
- This depolarization causes the Ca2+ channel door to open, then Ca2+ ions come out (REPOLARIZATION), Towards a more negative
- The action potential continues to pump until it passes the rest potential to become more negative (HYPERPOLARIZATION) until it returns to the -70 mV rest potential

Somatic Nerves System
The part of the peripheral nerves that functions as a carrier of information on the sensory and motor nerves, to the central nervous system and from the central nervous system
