What is the connections between 2 neurons called?
Synapses.
What are myelin sheaths?
A layer of sheath that covers and wraps around the axon, and helps speed up the transmission of electrical impulses.
What is the soma?
The body of the neuron that contains the nucleus, and makes proteins that help the neuron function.
