Nicotinic Acetylcholine Receptors

Meaning

Nicotinic Acetylcholine Receptors (nAChRs) are a class of ligand-gated ion channels located in the central and peripheral nervous systems, as well as skeletal muscle. These receptors are primarily activated by the neurotransmitter acetylcholine, playing a vital role in neuromuscular transmission, cognitive function, arousal, and attention. Their modulation is a key point in the interface between the nervous system and the endocrine system, influencing the release of various hormones.
