Document Summary
A neuron has one axon which carries messages to other neurons. Dendrites and axons increase a neuron"s cell surface area. A dendrite"s surface may branch out into one or many axon collaterals. The axon"s lower tip may divide into multiple smaller branches telodendria, at the end of which is a knob called the terminal button, which sits close to the dendritic spine or some part of another cell. This near-connection, synapse, includes the surfaces of the terminal button and the neighbouring dendritic spine as well as the space btwn them. It is the info. transfer site btwn neurons. Sensory neurons: conduct info from the sensory receptors in or on the body into. Multipolar neuron: majority; 3 or more processes (projections); motor. Three functions of neurons - the sc and the brain neurons from has a soma cerebellum muscles long axon and interneurons. Unipolar neuron: one process; mostly in sensory receptors. >one axon and dendrite extending in opp. directions; specialized;
