The sarcomere is the fundamental unit of muscle structure. Its capacity for contraction is the essential trait that makes muscles work. It has two primary components (1) thin filaments (each of which contains two strands of actin and a single strand of regulatory protein); and (2) thick filaments made of myosin (see diagram right).. Sarcomere and myocyte

The main components of the histology of a sarcomere are summarized below: Band A Thick filament zone, composed of myosin proteins. Zone H Central zone of band A, without actin proteins superimposed when the muscle is relaxed. Band I Zone of thin filaments, composed of actin proteins (without myosin). Z disks Each sarcomere divides into different lines, bands, and zone: "I" and ";A" bands, "M" and "Z" lines, and the "H" zone. - Z-lines define the boundaries of each sarcomere. - The M-line runs down the center of the sarcomere, through the middle of the myosin filaments. - The I-band is the region containing only thin filaments. An individual sarcomere contains many parallel myosin and actin filaments. The interaction of these proteins is at the core of the sliding filament theory. Sliding Theory of Muscle Contraction. The sliding filament theory can be best explained as the following. For a muscle contraction to take place, there must be a stimulation first to form an impulse (action potential) from a neuron … Sarcomere. Diagram of a sarcomere bounded by the Z-bands.

A sarcomere is defined as the segment between two neighbouring Z-lines (or Z-discs). In electron micrographs of cross-striated muscle, the Z-line (from the German "zwischen" meaning between) appears in between the I-bands as a dark line that anchors the actin myofilaments. Surrounding the Z-line is the region of the I-band (for isotropic ).

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.

Contracted Sarcomere Diagram

A sarcomere is defined as the region of a myofibril contained between two cytoskeletal structures called Z-discs (also called Z-lines), and the striated appearance of skeletal muscle fibers is due to the arrangement of the thick and thin myofilaments within each sarcomere (Figure 10.2.2).
