| synaptic endings | The somewhat enlarged, often club-shaped endings by which axons make synaptic contacts with other nerve cells or with effector cells (muscle or gland cells). As isolated, by homogenizing brain or spinal cord, they contain acetylcholine and the related enzymes. Terminals contain neurotransmitters of various kinds, sometimes more than one. These can be demonstrated by chemical analysis and immunocytochemical methods. See: synapse. Synonym: axonal terminal boutons, end-feet, neuropodia, pieds terminaux, synaptic boutons, synaptic endings, synaptic terminals, terminal boutons, bouton terminaux. (05 Mar 2000) |

| grape endings | An autodescriptive term applied to synaptic terminals at the ends of short, stalklike axon branches. (05 Mar 2000) |
|---|---|
| nerve endings | Specialised terminations of peripheral neurons. Nerve endings include neuroeffector junction(s) by which neurons activate target organs and sensory receptors (see receptors, sensory) which transduce information from the various sensory modalities and send it centrally in the nervous system. Presynaptic nerve endings are presynaptic terminals. (12 Dec 1998) |
| free nerve endings | A form of peripheral ending of sensory nerve fibres in which the terminal filaments end freely in the tissue. Synonym: terminationes nervorum liberae. (05 Mar 2000) |
| synaptic | <physiology> Pertaining to or affecting a synapse or synapsis. (10 Jan 1998) |
| synaptic boutons | The somewhat enlarged, often club-shaped endings by which axons make synaptic contacts with other nerve cells or with effector cells (muscle or gland cells). As isolated, by homogenizing brain or spinal cord, they contain acetylcholine and the related enzymes. Terminals contain neurotransmitters of various kinds, sometimes more than one. These can be demonstrated by chemical analysis and immunocytochemical methods. See: synapse. Synonym: axonal terminal boutons, end-feet, neuropodia, pieds terminaux, synaptic boutons, synaptic endings, synaptic terminals, terminal boutons, bouton terminaux. (05 Mar 2000) |
| synaptic cleft | <physiology> The narrow space between the presynaptic cell and the postsynaptic cell in a chemical synapse, across which the neurotransmitter diffuses. (10 Jan 1998) |
| synaptic conduction | The conduction of a nerve impulse across a synapse. (05 Mar 2000) |
| synaptic membranes | Cell membranes associated with synapses. Both presynaptic and postsynaptic membranes are included along with their integral or tightly associated specializations for the release or reception of transmitters. (12 Dec 1998) |
| synaptic phase | <cell biology> The specific pairing of the chromatids of homologous chromosomes during prophase I of meiosis. It allows crossing over to take place. (18 Nov 1997) |
| synaptic resistance | The ease or difficulty with which a nerve impulse can cross a synapse. (05 Mar 2000) |
| synaptic terminals | The somewhat enlarged, often club-shaped endings by which axons make synaptic contacts with other nerve cells or with effector cells (muscle or gland cells). As isolated, by homogenizing brain or spinal cord, they contain acetylcholine and the related enzymes. Terminals contain neurotransmitters of various kinds, sometimes more than one. These can be demonstrated by chemical analysis and immunocytochemical methods. See: synapse. Synonym: axonal terminal boutons, end-feet, neuropodia, pieds terminaux, synaptic boutons, synaptic endings, synaptic terminals, terminal boutons, bouton terminaux. (05 Mar 2000) |
| synaptic transmission | <physiology> The process of propagating a signal from one cell to another via a synapse. (10 Jan 1998) |
| synaptic vesicle | <cell biology> Intracellular vesicles found in the presynaptic terminals of chemical synapses, which contain neurotransmitter. During activity the vescles release their contents at the synapse and the neurotransmitter stimulate receptors on other cells. (10 Jan 1998) |
| synaptic vesicles | Membrane-bound compartments which contain transmitter molecules. Synaptic vesicles are concentrated at presynaptic terminals. They actively sequester transmitter molecules from the cytoplasm. In at least some synapses, transmitter release occurs by fusion of these vesicles with the presynaptic membrane, followed by exocytosis of their contents. (12 Dec 1998) |
