Document Summary

Functions such as protein synthesis, energy production, and metabolism. Contains nucleus, which houses chromosomes that contain your dna, or the genetic blueprint of who you are. Cell body is surrounded by a porous cell membrane that allows some molecules to flow into and out of the cell. ), dendrites(receive information from other neurons and relay it to the cell body), and axons(carries information to other neurons muscles, or glands. Axon covered by myelin sheath(insulating layer of fatty material. Composed of glial cells(support cells found in nervous system. Some digest dead neurons others provide physical and nutritional support for neurons, and others form myelin to help the axon carry information more efficiently. )). There"s a small gap between the axon of one neuron and the dendrites or cell body of another, part of the synapse(junction or region between the axon of one neuron and the dendrites or cell body of another).
