Synapse (redirected from axodendrosomatic synapse)

synapse /syn·apse/ (sin´aps) the site of functional apposition between neurons, where an impulse is transmitted from one to another, usually by a chemical neurotransmitter released by the axon terminal of the presynaptic neuron. The neurotransmitter diffuses across the gap to bind with receptors on the postsynaptic cell membrane and cause electrical changes in that neuron (depolarization/excitation or hyperpolarization/inhibition).

Diagram of three synapses. Nerve impulse is indicated by arrows, showing that the direction of passage is from the terminal arborization (TA) or nerve endings of the axon of one neuron to the dendrites (D) of another neuron.

syn·apse (snps, s-nps)

n.

The junction across which a nerve impulse passes from an axon terminal to a neuron, a muscle cell, or a gland cell.

---

Synapse

A connection between nerve cells, by which nervous excitation is transferred from one cell to the other.

synapse (siˑ·naps),

n the junction between two neurons across which nerve impulses are conducted.

---

synapse (sin´aps),

n the region of contact between the processes of two adjacent neurons forming the place where a nervous impulse is transmitted from the axon of one neuron to the dendrites of another. It also is called the
synaptic junction.

synapse

the junction between the processes of two neurons or between a neuron and an effector organ, where neural impulses are transmitted by chemical means. The impulse causes the release of a neurotransmitter (e.g. acetylcholine or norepinephrine) from the presynaptic membrane of the axon terminal. The neurotransmitter molecules diffuse across the synaptic cleft, bind with specific receptors on the postsynaptic membrane, causing depolarization or hyperpolarization of the postsynaptic cell. See also neuron.

adrenergic synapse

the neurotransmitter is norepinephrine. See also adrenergic (1).

axoaxonic synapse

see axoaxonic.

axodendritic synapse

see axodentritic.

axodendrosomatic synapse

one between the axon of one neuron and the dendrites and body of another.

axosomatic synapse

see axosomatic.

cholinergic synapse

the neurotransmitter is acetylcholine. See also cholinergic.

dendrodendritic synapse

one from a dendrite of one cell to a dendrite of another.

excitatory synapse

a synapse in which the transmission of impulses is electrical not chemical. Found only in fish and invertebrates.

inhibitory synapse

hyperpolarizing electrical current is used to raise the threshold for the stimulation of a discharge of an impulse from the particular kind of nerve cell, found only in fish.
