Document Summary
Axons: generally information transmitting areas (only one axon emerges from the cell body) Dendrites can branch at a large distance. Communication arrives to the dendrites while axon does majority of the outcome of information. The size of a dendrite tree tells us how much information is being input. Shape: pyramidal (triangular/pyramid looking) cells of hippocampus. Location: cerebellum (cerebellar cells, hippocampus (hippocampal cells, location in circuit: primary, secondary etc. Function: motor neuron, sensory neurons (input area of the neuron system) Interneuron (anything not a motor or sensory neuron) Receives information from other neurons and sensory receptors. Receives information from dendrites and if enough stimulation is received the message is passed on the axon. Axon (cid:272)arries (cid:374)euro(cid:374)s" (cid:373)essage to other (cid:271)ody (cid:272)ells. Covers the axon of some neurons to insulate and help speed neutral impulses. Of axon form junctions with other cells and release chemicals called neurotransmitters. Action potentials all look very similar making it next to impossible to differentiate between species.
