Document Summary
Information is transmitted from cell to cell across synapses. Neurons= most important part of the nervous system. Electrical signaling within neurons (from dendrites to axon terminal) A neuron has structures in common with other cells: Endoplasmic reticulum(er) several functions, incl. calcium regulation. Neurons are classified by shape, size, or function. Moto neurons : connect to muscle tissues, fire action potential, produce neurotransmitter to activate the muscles (muscle & glands) Take the outside sensory info, transfer to action potential, send it to brain. Interneurons: between two neurons , receive input from and send input to other neurons. One axon, many dendrites - projecting out from the cell body. The end of that axon also spread out a lot of axon terminals. One major branch that comes out fro the cell body but have multiple dendrites, A single extension that branches in two directions, forming a receptive pole and an output zone.
