Q

Insulated myelin while helping remove excess ions and neurotransmitters

17
Q

When a neuron is at rest

A

Resting Potential

18
Q

The positive sodium ions are on the outside, negative potassium ions are on the inside

A

Resting Potential

19
Q

Action Potential makes the ions switch places

A

Resting Potential

20
Q

Membrane of the Neuron that allows the sodium and potassium to move in and out of the channel

A

Semi- Permeable

21
Q

Neural impulse generated by the movement of positively charged atoms in and out of the axon membrane channels

A

Action Potential

22
Q

The increase in sodium ions moving inside the cell making the inside more positive then the negative

A

Depolarization

23
Q

Results in the potassium ions to get pushed outside

A

Depolarization

24
Q

After the charge moves to the next section of the axon channel

A

Hyperpolarization

25
The sodium ions shift back outside of the channel
Hyperpolarization
26
Level of stimulation that must be exceeded for the neuron to fire of generate an electrical impulse
Threshold
27
Either cells fire if the charge inside reaches a threshold or it doesn't fire
All or nothing principle
28
Junction between the acon tip of the sending neuron and the dendrite of the recieving neuron
Synapse
29
Tiny Gap at the junction that is called the _______ gap of cleft
Synape
