One equation for a chemical reaction in a sweat gland is the breakdown of acetyl-CoA to produce acetylcholine, a neurotransmitter involved in stimulating sweat gland activity. The reaction can be represented as: Acetyl-CoA + Choline -> Acetylcholine + CoA
William Bayliss and Ernest Starling discovered the neurotransmitter acetylcholine in 1902. This discovery was significant in understanding the role of chemical messengers in the nervous system and how they regulate physiological processes.
Acetylcholine is broken down by the enzyme acetylcholinesterase into acetate and choline. This breakdown process is essential for terminating the action of acetylcholine at the synapse, allowing for proper signaling between nerve cells. Excess acetylcholine breakdown can lead to conditions such as myasthenia gravis.
The antidote for excess acetylcholine is atropine, which acts as a competitive antagonist at cholinergic receptors. Atropine inhibits the effects of acetylcholine by blocking its binding, therefore reversing toxicity symptoms such as bradycardia, bronchoconstriction, and excessive salivation caused by excess acetylcholine.
Acetylcholinesterase is an enzyme that breaks down the neurotransmitter acetylcholine in the nervous system. It plays a crucial role in regulating nerve signals and muscle contractions by rapidly hydrolyzing acetylcholine into choline and acetate. Inhibition of acetylcholinesterase can lead to an accumulation of acetylcholine, which can disrupt normal nerve signaling and muscle function.

Parasympathetic system has acetylcholine as its chemical mediator.
Acetylcholine is the chemical that transmits signals across the neuromuscular junction. It binds to receptors on the muscle cell membrane, leading to muscle contraction.
Acetylcholine is the primary chemical transmitter released at the neuromuscular junction. It binds to acetylcholine receptors on the muscle cell membrane, leading to muscle contraction.

nicotinic acetylcholine receptors (nAChR, also known as "ionotropic" acetylcholine receptors) are particularly responsive to nicotinemuscarinic acetylcholine receptors (mAChR, also known as "metabotropic" acetylcholine receptors) are particularly responsive to muscarine.Nicotinic and muscarinic are two main kinds of "cholinergic" receptors.
Acetylcholine is the neurotransmitter at the neuromuscular junction.
