Acetylcholine (redirected from Acetylcholine chloride)

acetylcholine /ac·e·tyl·cho·line/ (ACh) (as?e-til-) (as?e-tel-ko´len) the acetic acid ester of choline, which is a neurotransmitter at cholinergic synapses in the central, sympathetic, and parasympathetic nervous systems; used in the form of the chloride salt as a miotic.

a·ce·tyl·cho·line (-stl-kln)

n. Abbr. Ach

A white crystalline derivative of choline that is released at the ends of nerve fibers in the somatic and parasympathetic nervous systems and is involved in the transmission of nerve impulses in the body.

Acetylcholine

a molecule released by neurons at the neuromuscular junction that causes muscle contraction.

acetylcholine (·sēˈ·tl·kōˑ·lēn),

n neurotransmitter that is produced in the central and parasympathetic autonomic nervous systems. It is the most prevalent neurotransmitter in the body and is crucial to arousal, learning, memory, and motor function.

acetylcholine (as´tilkō´lēn, sē´til),

n 1. an acetate ester of choline that serves as a neurohumoral agent in the transmission of an impulse in autonomic ganglia, parasympathetic postganglionic fibers, and somatic motor fibers.
n 2. an ester of choline actively involved as a chemical mediator at the neuromuscular junction, at autonomic ganglia, and between parasympathetic nerve endings and visceral effectors.

acetylcholine

the acetic acid ester of choline, normally present in many parts of the body and having important physiological functions. It is a neurotransmitter at cholinergic synapses in the central, sympathetic and parasympathetic nervous systems. It is not used clinically but it is the classical cholinergic agonist. Abbreviated ACh.

acetylcholine receptors

structures located at the endorgans, e.g. at the skeletal muscle fibers. The myofibers are stimulated to contract by the interaction of acetylcholine with acetylcholine receptors which are located on the motor end plate or postsynaptic sarcolemma. See also neuromuscular junction.

acetylcholine Neurophysiology An acetic acid ester of choline-a substance that functions as a major cholinergic neurotransmitter released from vertebrate neurons into the synaptic spaces after stimulation from the PNS Action Vasodilation, cardiac inhibition, GI peristalsis; it is involved in the control of thought, mood, sleep, muscles, bladder, sweat glands
