Electrical synapse — An electrical synapse is a mechanical and electrically conductive link between two abutting neuron cells that is formed at a narrow gap between the pre and postsynaptic cells known as a gap junction. At gap junctions, such cells approach within… … Wikipedia
electrical synapse — A connection between two electrically excitable cells, such as neurons or muscle cells, via arrays of gap junctions. This allows electrical coupling of the cells, and so an action potential in one cell moves directly into the other, without the 1 … Dictionary of molecular biology
synapse — A connection between excitable cells, by which an excitation is conveyed from one to the other. (1) Chemical synapse: one in which an action potential causes the exocytosis of neurotransmitter from the presynaptic cell, which diffuses across the… … Dictionary of molecular biology
Synapse (disambiguation) — A synapse is a neural junction used for communication between neurons.It usually refers to a chemical synapse, but also could be an electrical synapse or immunological synapse.Synapse may also refer to: * Synapse Software, an American computer… … Wikipedia
Synapse — The point of connection usually between two nerve cells. Specifically, a synapse is a specialized junction at which a nerve cell (a neuron) communicates with a target cell. The neuron releases a chemical transmitter (a neurotransmitter) that… … Medical dictionary
synapse — n. the minute gap across which nerve impulses pass from one neurone to the next, at the end of a nerve fibre. Reaching a synapse, an impulse causes the release of a neurotransmitter, which diffuses across the gap and triggers an electrical… … The new mediacal dictionary
Chemical synapse — This article is about chemical synapses of the nervous system. For other uses, see Synapse (disambiguation). Illustration of the major elements in chemical synaptic transmission. An electrochemical wave called an action potential travels along… … Wikipedia
Ribbon synapse — Latin synapsis fasciolaris Code TH H2.00.06.2.00024 Ribbon synapse is a type of synapse linking some particular neuronal cells, which have unique features, such as their morphology, mechanisms of multivesicular release and calcium channel positio … Wikipedia
Silent synapse — In neuroscience, a silent synapse is an excitatory glutamatergic synapse whose postsynaptic membrane contains NMDA type glutamate receptors but no AMPA type glutamate receptors. These synapses are so named because normal AMPA receptor mediated… … Wikipedia
Squid giant synapse — The squid Giant Synapse Anatomy This chemical synaptic junction was first recognized by John Zachary Young in 1939.The squid giant synapse (Fig 1) is the largest chemical junction in nature. It lies in the stellate ganglion on each side of the… … Wikipedia
