When a muscle contracts the actin is pulled along myosin toward the center of the sarcomere until the actin and myosin filaments are completely overlapped. Sliding filament model of contraction. In 1954 using high resolution microscopy these scientists noticed changes in the sarcomeres as muscle tissue shortened.
Niedergerke 1954 and h.
In other words for a muscle cell to contract the sarcomere must shorten. In 1954 using high resolution microscopy these scientists noticed changes in the sarcomeres as muscle tissue shortened. Niedergerke 1954 and h. When a muscle contracts the actin is pulled along myosin toward the center of the sarcomere until the actin and myosin filaments are completely overlapped.
