Document Summary
Classification of neurons: shape: pyramidal cells of hippocampus, location: cerebellum (cerebellar cells) hippocampus (hippocampal, function cells) Or location in circuit: primary, secondary, etc. : motor neuron, sensory neuron (responds and sends data, interneuron (anything not a motor or sensory neuron) Cell body: receives info from dendrites of enough stimulation is received- message goes to axon. Axon: carries neuron message to the other cells. Mylein sheath: covers axon to insulate and speed impulses. Terminal boutons: end of the axon, form junctions with cells and release neuron transmits. Action potential is a non-decaying electrical signal (little heart beats), look very similar from one nervous system to the next. If a cell fires an electrical signal, generating action potentials allows it to communicate with other cells (think of the action potential as a word) Always involved in some sort of communication (some cells may be continuous, where others have some action potentials spread out.
