Having the nucleus and most of the cytoplasm.
Receiving the signals (action potentials)
Long fiber that sending a signal (action potential)
Working like a wire
A membrane that surrounds the axon in some neurons
Helping speed up the signal (Action Potential)
Node of Rainiver
Step 1: Threshold reached
The strength a stimuli needs to be in order to cause an action potential
Step 2: Sodium let into cell
The gap between two neurons.
Step 3: Action potential travels down axon
Step 4: Action potential reaches axon terminal
Step 5: Neurotransmitter released and the next neuron is activated
A chemical that is activated by an action potential and sends the signal to the next neuron.
Peripheral Nervous System
Part of the nervous system that is not the brain or spinal cord
Central Nervous System
Part of the nervous system that includes the brain and spinal cord
