Document Summary

Features unique to neurons: dendrites: generally information receiving areas (input region, axons: generally information transmitting areas ( only one axon emerges form the cell body, output) Interneuron( anything not a motor or sensory neuron) What we see in reality is not what we see in the textbook. Classi cation of neurons: shape:(pyramidal cells of hippocampus, location:( cerebellum- cerebellar cells and hippocampus- hippocampus cells) or location in circuit: primary, secondary etc, function, motor neuron, sensory neuron c. Mitral cell: from relay station involved in smell. Receiving inputs from cells, the extent and quality of it how many inputs are arriving. Cells in the nervous system from electricity and chemicals. Studies show individuals brain cells use chemicals, Tip of dendrite the tip of the axon, signalling is down with electricity( transmitting information) Use electricity to send a message is much faster than chemical. When individuals cells community with other cells they use chemical.
