Document Summary
The basic building block of the nervous system. Cell body at one end: nucleus. Myelin: fat coating on the outside of the axon. In between schwann cells: nodes of ranvier. The far end of the neuron is the axon terminals: can talk to an endocrine cell, muscle cell, neuron, etc. Based on the overall structure of the cells itself. Unipolar neuron: not very common, composed of soma and axon, needs something to directly stimulate the cell body the transmit anything. Has a broader number of cells than unipolar. Bipolar neuron: very distinct anatomy, one dendrite, one main axon coming off the cell body, only receives info from a small subset of cells and projects to another small subset of cells. Multipolar neuron: have a large number of dendritic branches coming off the cell body, one axon coming off. The axons can bifurcate multiple times: purkinge cell. Looks like a star explosion: pyramidal cell. Conveys information to a neuron: efferent.
