ANATOMY

Detailed explanation-1: -Acetylcholine (ACh) is an important neurotransmitter that plays a role in brain functions, such as memory, and body functions, such as muscle contractions to move your muscles. Low levels of acetylcholine are associated with memory issues and muscle disorders.

Detailed explanation-2: -Muscle contraction is controlled by receptors in the muscle cell membranes that respond to the neurotransmitter acetylcholine when it is released from motor neurons.

Detailed explanation-3: -Acetylcholine is a type of chemical messenger, or neurotransmitter, that plays a vital role in the central and peripheral nervous system. It is important for muscle control, autonomic body functions, and in learning, memory, and attention.

Detailed explanation-4: -Acetylcholine is a neurotransmitter found in the central nervous system (CNS) and peripheral nervous system (PNS). It plays an important role in many of your body’s functions, including muscle movement, memory and cognition, REM sleep, and attention and learning.

Detailed explanation-5: -When acetylcholine binds to acetylcholine receptors on skeletal muscle fibers, it opens ligand gated sodium channels in the cell membrane. Sodium ions then enter the muscle cell, stimulating muscle contraction.
