Acetylcholine definition anatomy. Acetylcholine ach is an organic chemical that functions in the brain and body of many types of animals and humans as a neurotransmitter a chemical message released by nerve cells to send signals to other cells such as neurons muscle cells and gland cells. Acetylcholine an ester of choline and acetic acid that serves as a transmitter substance of nerve impulses within the central and peripheral nervous systems. These receptors can be divided into two main types of distinct receptors nicotinic and muscarinic.

Acetylcholine is synthesized and liberated by the action of the enzyme choline acetyltranferase from the compounds choline and acetyl coenzyme a acetyl coa which occurs in all cholinergic neurons. Pesticides of the organophosphate and carbamate types act to paralyze. When activated it causes the contraction of skeletal muscles and activates glandular functions in the endocrine system.

Acetylcholine definition is a neurotransmitter c7h16no2 released at autonomic synapses and neuromuscular junctions and formed enzymatically in the tissues from choline. A neurotransmitter released by nerves that is essential for communication between the nerves and muscles. Acetylcholine definition the acetic acid ester of choline c7h17no3 released and hydrolyzed during nerve conduction and causing muscle action by transmitting nerve impulses across synapses.

Medical definition of acetylcholinesterase. Twisted around actin filaments and covver the acin binding sites. An enzyme that breaks down the neurotransmitter acetylcholine at the synaptic cleft the space between two nerve cells so the next nerve impulse can be transmitted across the synaptic gap.

Acetylcholine is the chief neurotransmitter of the parasympathetic nervous system the part of the autonomic nervous system. Acetylcholine is a chemical that is found between the nerve synapses or gaps between nerve cells. A protein attached to trypomyosinn and binds to ca altering its configuration which results in pulling the tropomyosin away from the actin binding sites which allows myosin to come in and bind to it contraction.
