A fatty coating which speeds up the rate

53
Q

Synapse

A

Gap between neurons

54
Q

Neurotransmitters

A

Chemical messengers

55
Q

Action potential or nerve impulse

A

When the neuron fires dependability of the cell membrane changes which permits electrically charged ions of potassium and sodium to enter the cell causing the release of the new transmitter

56
Q
