Synapse
|
|
Synapse A tiny gap between the ends of nerve fibers across which nerve impulses pass from one neuron to another; at the synapse, an impulse causes the release of a neurotransmitter, which diffuses across the gap and triggers an electrical impulse in the next neuron.
RELATED TERMS--------------------------------------
Nerve
Tissue that conveys sensation, temperature, position information to the brain.
Neuron
A cell specialized to conduct and generate electrical impulses and to carry information from one part of the brain to another.
Synapse
A tiny gap between the ends of nerve fibers across which nerve impulses pass from one neuron to another; at the synapse, an impulse causes the release of a neurotransmitter, which diffuses across the gap and triggers an electrical impulse in the next neuron.
Neurotransmitter
Specialized chemical messenger (eg, acetylcholine, dopamine, norepinephrine, serotonin) that sends a message from one nerve cell to another. Most neurotransmitters play different roles throughout the body, many of which are not yet known.

Spasm
A condition in which a muscle or group of muscles involuntarily contract.
