Значение термина acetylcholine в knolik
acetylcholine - acetylcholine (Ach)
acetylcholine - Substance secreted at the ends of many nerve fibres (cholinergic fibres) when nerve impulses arrive there. Where such a nerve fibre ends at a synapse, e.g. in sympathetic and parasympathetic ganglia, ACh is the agent which stimulates the contiguous nerve cell and hence in effect 'passes the impulse on'; and similarly where the fibre connects with an effector, e.g. at the nerve-muscle junction. After secretion ACh is very rapidly destroyed by the enzyme cholinesterase, being broken down into acetate and choline. It is the acetyl ester of choline.
