The sarcomere is the contractile unit of muscle. This means it is the part of muscle that does the actual contracting. There are several terms that you will need to know. They are thick filament (myosin), thin filament (actin), Z line, I band, A band, H zone, and M line.

Z lines are composed of a mixture of actin myofilaments and molecules of the highly elastic protein titin crosslinked by alpha-actinin. Sarcomere Structure. To understand the sliding filament model requires an understanding of sarcomere structure. A sarcomere is defined as the segment between two neighbouring, 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. 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).

No differences in sarcomere structure and titin isoform composition were observed. Likewise, in vivo cardiac function and myocardial structure was unaltered in Rbm24 HET mice compared to WT,

Desmin protein is composed by 470 amino acids divided into an αhelical central zone and two globular structures, the NH 2 and COOH terminal regions The sarcomere is the molecular structure that allows muscle cells to contract and generate force. Find out how the sarcomere works and why it is central to the mechanism of disease in heart failure and hypertrophic cardiomyopathy. Sarcomeres = Striations Remember how skeletal muscle is also called striated muscle? Probably not but that's okay Striations are basically lines Sarcomeres next to one another cause these striations, or lines, and that's why skeletal muscle can also be called striated muscle!
