D. actin and myosin filaments change positions relative to each other. D. Contractile units known as sarcomeres ...The sliding filament theory explains that when a muscle is activated and movement occurs, these two interlocking filaments can grab onto each other and pull, which causes the myofibril to shorten. This shortening is called a muscle contraction. There are three types of muscle cells in the human body:The sliding-filament theory of muscle contraction is explained. Finally, the processes by which nerves excite muscle contraction (excitation-contraction coupling) are outlined, again relating variations in these processes in the two types of muscle to differences between them in their role in the body.

These filaments slide in and out between each other to form a muscle contraction hence called the sliding filament theory! The diagram above shows part of a myofibril called a sarcomere. This is the smallest unit of skeletal muscle that can contract. Sliding Filament Theory In its most basic form: • Muscle contraction occurs when the myosin and actin filaments slide across each other. • What actually occurs is myosin pulls the actin in. • This shortens the muscle and is a muscle contraction.
