Document Summary

Cell body (stoma): cells in the nervous system that communicate with one another to perform information-processing tasks sensory, motor, interneuron composed of the cell body, the dendrites, and the axon. 100 billion neurons in your brain specializes in sensory, motor, and connective functions group of neurons forms a nerve neurons that fire together wire together bundle of axons like cables and are part of peripheral nervous system. 3 types: afferent, efferent, also mixed: afferent: sensory neurons carry impulses from sense organs toward the cns communicate with interneurons, efferent: carry nerve impulse away from cns to muscles and plands. Mostly motor neurons the part of a neuron that coordinates information-processing tasks and keeps the cells alive contains nucleus largest component of neuron protein synthesis, energy production, and metabolism take place here. Dendrite: the part of a neuron that receives information from other neurons and relays it to the cell body.
