One of the functional units of a myofibril is the sarcomere. The word sarcomere comes from the Greek words sarx, meaning flesh, and meros, meaning part.
Not every relation is a function. But every function is a relation. Function is just a part of relation.
The cubic function.
Range
A formula or graph are two ways to describe a math function. How a math function is described depends on the domain of the function or the complexity of the function.

Sarcomere
sarcomere and sarcolemma are two different things. a sarcomere is between two d zisks of a myofiber (muscle fiber). a sarcolemma is a plasma membrane. there are many sections of sarcomere under the layer of sarcolemma.
The shortening of the sarcomere is called muscle contraction. This occurs when actin and myosin filaments slide past each other, causing the sarcomere to shorten.
The outer boundaries of the sarcomere are defined by the Z-discs or Z-lines, which mark the ends of the sarcomere unit. These Z-discs separate one sarcomere from the next and provide attachment points for actin filaments.
The two main filaments composing the sarcomere are action and myocin.
No, actin filaments do not extend the entire length of a sarcomere. Actin filaments are found in the I band and span from the Z line towards the middle of the sarcomere, where they overlap with myosin filaments. The myosin filaments extend the length of the sarcomere in the A band.
The three sections along the length of a sarcomere are the A band, the I band, and the H zone. The A band is the dark region in the center of the sarcomere that contains both thick and thin filaments, while the I band is the light region at the ends of the sarcomere that contains thin filaments only. The H zone is the region in the center of the sarcomere where only thick filaments are present.
The dark staining area of a sarcomere is the A band, which contains overlapping thick and thin filaments. The A band gives the sarcomere its striated appearance and is involved in muscle contraction.
