The arrangement of actin and myosin myofilament within a sarcomere is crucial in the mechanism of muscle contraction. Huxley and rolf niedergerke from the university of c. To address a common problem of teaching the sliding filament theory that is students have difficulty in visualizing how the component proteins of the sarcomere differ how they organize themselves into a single working unit and how they function in relation to each other we have devised a simple model with inexpensive materials to be built by students in the fourth year of an.
I thought the best way to explain this process was by animation.
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 model proposed to explain muscle contraction in 1954 has proven to be very robust. Hanson 1954 explains how muscles in the human body contract to produce force.
