Document Summary
Conduct impulses (wave of depolarization along the plasma membrane) Signals pass from neuron to target cell via synapses: supporting cells. Structural and nutritional support of neurons, electrical insulation. Brain and spinal cord peripheral nervous system (pns) Keeps other tissues of the body in communication with. A nerve is a collection of fibers that conduct impulses to and/or from the cns impulses that travel toward. Cns are sensory. impulses that leave the cns are motor. most nerves are mixed nerves a ganglion is a collection of neurons outside the cns. Tracts: in the cns concentrations of neuronal cell bodies. Nuclei: in the cns enteric nervous system. Types of neurons vary in size and shape within the nervous system classified according to shape and location arrangement of their processes. Unipolar (pseudounipolar) = have one process, the axon, that divides close to the cell body into two long axonal branches. Typically receives input from a single synapse of an axon www. bu. edu/histology.
