Document Summary
Neurons: cells in the nervous system that communicate with one another to perform information processing tasks. Santiago ramon y cajal, new technique for staining neurons in the brain. Information processing units of the brain and that even though he saw gaps between neurons they had to communicate in some way. Cell body: the part of the neuron that coordinates information processing tasks and keeps the cell alive (soma) protein synthesis, energy production, metabolism take place here. Nucleus, houses chromosomes that contain your dna or the genetic blueprint of who you are. Dendrites: receives information from other neurons and relays it to the cell body. Axon: transmits information to other neurons, muscles, or glands. Myelin sheath: an insulating layer of fatty material. Glial cells: support cells found in the nervous system, digest parts of dead neurons, provide physical and nutritional support for neurons. Myelin performs this same function for an axon.
