Acetylcholine is a neurotransmitter in the nervous system that plays a key role in muscle contraction, cognition, and memory. It is synthesized in the brain and peripheral nervous system. Dysfunction in acetylcholine signaling is associated with various neurological disorders such as Alzheimer's disease.

What is the neurotransmitter at the neuromuscular junctions?
acetylecholine
What neurotransmitter is released at the neuromuscular junction?
Acetylcholine is the primary neurotransmitter released at the neuromuscular junction. It is responsible for transmitting signals from motor neurons to muscle fibers, leading to muscle contraction.
How does antipsychotic drug work?
Anticholinergic drugs inhibit the enzyme Acetylcholinesterase enzyme which breaks down acetylcholine. Therefore with more Acetylecholine neurotransmitters present. The cholinergic receptors such as the muscarinic and nicotinic receptors are more likely to find an Ach chemical to join with so their reaction takes place. An example of this is Neostigmine and Physostigmine which improve the ability to void-treating urinary retention or reducing intraocular pressure-treating glaucoma.
What does your heart do when your heart rate increase?
The heart rate increases because of your bodies cells need more oxygen during activity. Nerves in the heart make the pacemakers fire electrical impulses faster because they release epinephrine and neropinephrine and thus the heart rate increases.
