neuron parts

metabolic center of the neuron, contains organelles (except centrioles)

convey incoming messages toward the cell body

conduct nerve impulses away from the cell body

tiny gaps between axon terminals, separates neurons

protects and insulates nerve fibers and increases the transmission rate of nerve impulses, axons outside the CNS are myelinated by Schwann Cells

gaps or indentations in the myelin sheath

consists of dense collections of myelinated fibers

contains mostly unmyelinated fibers and cell bodies
