Acetylcholine (2026)

ACh is released at neuromuscular junctions to stimulate skeletal muscles to contract.

ACh is essential for initiating rapid eye movement (REM) sleep. Synthesis and Breakdown acetylcholine

Acetylcholine (ACh) is a vital chemical messenger—or neurotransmitter—that facilitates communication between neurons in both the central nervous system (brain and spinal cord) and the peripheral nervous system (nerves throughout the body). As the first neurotransmitter discovered (in 1914), it plays a crucial role in regulating muscle movement, cognitive functions, and autonomic bodily processes. Key Functions of Acetylcholine ACh is released at neuromuscular junctions to stimulate

It plays a central role in learning, memory, arousal, and attention. As the first neurotransmitter discovered (in 1914), it

Acetylcholine acts as a versatile mediator, responsible for both excitatory (stimulating) and inhibitory (slowing) signals.

Acetylcholine is synthesized within nerve terminals from two primary components: choline (often derived from diet) and acetyl coenzyme A. An enzyme called facilitates this process. Acetylcholine (ACh): What It Is, Function & Deficiency
