19
Q

Area of the brain responsible for facial expressions and breathing regulation

A

Pons

20
Q

Nervous system division in charge of resting and digesting

A

Parasympathetic

21
Q

Nervous system division in charge of fight or flight

A

Sympathetic division

22
Q

At the point of stimulation the membrane becomes permeable to Na+ for an instant and they quickly move into the cell.

A

Depolarization

23
Q

K+ automatically leave the cell until the sale is back to its resting state.

A

Repolarization

24
Q

K+ concentration is much higher inside the cell. The Na+ concentration is much higher outside the cell.

A

Resting

25
Q

The length of time it takes a neuron to return to its resting potential after being stimulated. A neuron cannot be stimulated during this period.

A

The factory
