MICROANATOMY

Detailed explanation-1: -Acetylcholinesterase (AChE) is a cholinergic enzyme primarily found at postsynaptic neuromuscular junctions, especially in muscles and nerves. It immediately breaks down or hydrolyzes acetylcholine (ACh), a naturally occurring neurotransmitter, into acetic acid and choline.

Detailed explanation-2: -Free acetylcholine within the synaptic cleft is degraded by an enzyme called acetylcholinesterase. This enzyme assures that no excess of acetylcholine remains in the synaptic cleft to cause the continuous activation of receptors. Acetylcholine has different roles and functions at different synapses throughout the body.

Detailed explanation-3: -AChE inhibitors or anti-cholinesterases inhibit the cholinesterase enzyme from breaking down ACh, increasing both the level and duration of the neurotransmitter action.

Detailed explanation-4: -Acetylcholinesterase (generally referred to as cholinesterase): an enzyme that rapidly breaks down the neurotransmitter, acetylcholine, so that it does not over-stimulate post-synaptic nerves, muscles, and exocrine glands.

Detailed explanation-5: -Acetylcholine. Acetylcholine action is terminated by acetylcholinesterase, an enzyme present in the synaptic cleft. Acetylcholinesterase degrades acetylcholine into choline and acetate molecules. Choline is then transported back into the presynaptic terminal and used in the synthesis of new acetylcholine.
