3
Q

A
Also found in the brain and spinal cord. Woke to maintain the health of the neuron cells. Glial= glue
4
Q
Firing process of a neuron
A
- Resting potential->
Na outside, K inside, Axon Gates closed (no flush) - Threshold->
Na same, K same, Axon gates open (lever pressed/valve opens) - Action Potential (FIRE)
Na and K switch (water flows) - refractory period
Na and K switch back, Axon gates close (Rest)
5

Smooth muscle movement
Excess= epilepsy
