Sliding Filament Theory 3d Model. Niedergerke 1954 and h. You will present your model on a segment of the fictitious show csi the science revealed targeted to middle and high school students.
The mechanism of muscle contraction is explained by sliding filament model. Sliding filament theory in muscle contraction duration. In 1954 using high resolution microscopy these scientists noticed changes in the sarcomeres as muscle tissue shortened.

According to the sliding filament theory the myosin filaments of muscle fibers slide past the actin filaments during muscle contraction while the two groups of filaments remain at relatively constant length. This theory was proposed by h e huxley and j. The sliding filament theory explains the basis of skeletal muscle contraction and specifically deals with the movement of myosin heads along an actin fiber in the sarcomere. According to the sliding filament theory the myosin filaments of muscle fibers slide past the actin filaments during muscle contraction while the two groups of filaments remain at relatively constant length.
