Document Summary

100 billion neutrons in your brain! neurons: cells in nervous system that communicate for information processing tasks. Intricate drawings of neutrons. sliced brains, stained, drew what he saw. Neurons comunicate, do not physically touch neurons: cell body, dendrites, axon cell body (soma): coordinates information processing tasks. keeps cell alive. largest part. Nucleus (dna), energy production, metabolism dendrites: receive info fro other neurons and relay info to cell body. communication. little branches. many per neuron axon: transmits info other neurons, muscles, or glands. only one per neuron. can be up to. Microglia (immune function. help remove viruses, dead neurons) Astrocytes (nutritional supports) dendrites and axons don"t physically touch synapse: space between axon and dendrites from different neruons. each have many dendrites and many synapses, thus many messages can be transmitted constant. kids have more synapses than adults. Sensory neurons recieven info from the 5 senses from the environment, these are to the brain via the spinal cord.
