Muscles Presentation - Includes, muscle structure, sarcomere structure and sliding filament theory. Sarcomere structure When viewed under a microscope, muscle fibers of varied lengths are organized in a stacked pattern. The myofibril strands, thereby actin and myosin, form bundles of filament arranged parallel to one another. When a muscle in our body contracts, it is understood that the way this happens follows the sliding filament theory.

They are highly organised within skeletal and cardiac muscle which give a striped/striated appearance to the muscle. A sarcomere is the portion of a myofibril that lies between two successive Z disks.

A sarcomere is defined as the segment between two neighboring, parallel Z-lines. Z lines are composed of a mixture of actin myofilaments and molecules of the highly elastic protein titin crosslinked by alpha-actinin.

After observing under the microscope, a stacked pattern organized with a varied length of muscle fiber cells is seen. The bundle of filament arranged parallel to another is myofibril strands. Myofibrils consist of repeating contractile units called sarcomeres, which are made of two protein myofilaments The thick filament (myosin) contains small protruding heads which bind to regions of the thin filament (actin) Movement of these two filaments relative to one another causes the lengthening and shortening of the sarcomere Sarcomere structure When viewed under a microscope, muscle fibers of varied lengths are organized in a stacked pattern.
