Web28 Sep 2024 · A muscle cell, or fibre, is made up of multiple different filaments. The main two of these are called myosin and actin. Myosin is also known as the thick filament, because as shown in the diagram below, it has many strands and many heads. These heads connect with the actin filaments (also shown below) which are called the thin filaments. WebThere are thick (myosin) and thin filaments (actin) that slide onto each other.

WebThin filaments, anchored at their ends by the Z-discs, do not extend completely into the central region that only contains thick filaments, anchored at their bases at a spot called the M-line. A myofibril is composed of many sarcomeres running along its length; thus, myofibrils and muscle cells contract as the sarcomeres contract. Web28 Mar 2024 · They noticed that one zone of repeated sarcomere, later called the “A band,” maintained a constant length during contraction. The A band has a higher content of thick myosin filament, as expected by the area’s rigidity. The A band is the area in the center of the sarcomere where thick and thin filaments overlap.
