Meat can fasciculate, or twitch, after being cut due to the presence of residual energy and nerve endings within the muscle tissues. Even after an animal is slaughtered, its muscle cells can retain adenosine triphosphate (ATP), the energy molecule necessary for muscle contraction. When the meat is cut and the muscle cells are exposed to air, the remaining ATP can trigger muscle fibers to contract, causing the fasciculation or twitching effect. This phenomenon is more commonly observed in freshly

Freshly cut meat can fasciculate, or twitch, due to residual electrical activity and the sudden influx of calcium into the muscle cells. When the muscle is cut, calcium is released from storage sites within the cells, triggering a contraction. Even after death, some muscle cells remain reactive to this calcium surge, causing involuntary contractions. This phenomenon is normal and fades as the muscle depletes its energy stores and loses the ability to contract. #didyouknow #medicalfacts #viral #m

Pectoralis minor muscle is a thin, triangular muscle, situated at the upper part of the chest, beneath the pectoralis major in the human body. It arises from ribs III-V; it inserts onto the coracoid process of the scapula. It is innervated by the medial pectoral nerve. Its function is to stabilise the scapula by holding it fast in position against the chest wall. #fyp #f
