MUSCLE PHYSIOLOGY

Detailed explanation-1: -Acetylcholine has different roles and functions at different synapses throughout the body. In the somatic nervous system, acetylcholine is used at the neuromuscular junctions, triggering the firing of motor neurons and affecting voluntary movements.

Detailed explanation-2: -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.

Detailed explanation-3: -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-4: -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-5: -Acetylcholine is the neurotransmitter at neuromuscular junctions, at synapses in the ganglia of the visceral motor system, and at a variety of sites within the central nervous system.
