Neuron Function

Dendrites

ltrinosky — 2014-12-14 23:23:50 UTC

Branched fiber that extends outward from the cell body and carries information into the neuron; receiver for incoming messages

Soma

ltrinosky — 2014-12-14 23:27:10 UTC

The part of a cell (such as a neuron) containing the nucleus, which includes the chromosomes; also called the cell body

Axon (Axoff - jk)

ltrinosky — 2014-12-14 23:29:16 UTC

In a nerve cell, an extended fiber that conducts information from the soma to the terminal buttons. Information travels along the axon in the form of an electric charge called the action potential.

Terminal Buttons

ltrinosky — 2014-12-14 23:32:06 UTC

Tiny bulblike structures at the end of the axon that contain neurotransmitters that carry the neuron's message into the synapse

Action Potential

ltrinosky — 2014-12-14 23:32:28 UTC

The nerve impulse caused by a change in the electrical charge across the cell membrane of the axon. Wen the neuron "fires," this charge travels down the axon and causes neurotransmitters to be released by the terminal buttons.

Synapse

ltrinosky — 2014-12-14 23:36:33 UTC

The microscopic gap that serves as a communications link between neurons. Synapses also occur between neurons and the muscles or glands they serve

Synaptic Transmission

ltrinosky — 2014-12-14 23:38:42 UTC

The relaying of information across the synapse by means of chemical neurotransmitters

Neurotransmitter

ltrinosky — 2014-12-14 23:40:20 UTC

Chemical messenger that relays neural messages across the synapse. Many neurotransmitters are also hormones

Vesicles

ltrinosky — 2014-12-14 23:41:25 UTC

When the electrical impulse arrives at the terminal buttons, tiny bubblelike vesicles (sacs) inside them burst and release their chemical contents, known as neurotransmitters
