Muscle Contraction and Relaxation Mechanisms Explained

This lecture covers the fundamental mechanisms of muscle contraction and relaxation. It begins with an introduction to muscle physiology, including the structure of muscle fibres and the roles of actin and myosin. The mechanism of muscle contraction is explored in detail, focusing on the role of acetylcholine, calcium pathways, and actin-myosin interactions, followed by the process of muscle relaxation, including dephosphorylation and latch bridge mechanisms. Finally, the session concludes...
