1. Myofibril

   A myofibril (also known as a muscle fibril or sarcostyle) is a basic rod-like organelle of a muscle cell. Skeletal muscles are composed of long, tubular cells known as muscle fibers, and these cells contain many chains of myofibrils. Each myofibril has a diameter of 1–2 micrometres. They are created during embryonic development in a process known as myogenesis. Myofibrils are composed of long proteins including actin, myosin, and titin, and other proteins that hold them together. These proteins are organized into thick, thin, and elastic myofilaments, which repeat along the length of the myofibril in sections or units of contraction called sarcomeres. Muscles contract by sliding the thick myosin, and thin actin myofilaments along each other.

1. myofibril

   A myofibril is a basic rod-like unit of a muscle cell. It is a long, cylindrical organelle found in muscle cells that plays a role in muscle contraction and relaxation. Myofibrils are composed of proteins called actin and myosin, which form repeating contractile units known as sarcomeres.

1. Myofibril

   A myofibril is a basic rod-like unit of a muscle. Muscles are composed of tubular cells called myocytes, also known as muscle fibers, and these cells in turn contain many chains of myofibrils. They are created during embryo development in a process known as myogenesis. Myofibrils are composed of long proteins such as actin, myosin, and titin, and other proteins that hold them together. These proteins are organized into thin filaments and thick filaments, which repeat along the length of the myofibril in sections called sarcomeres. Muscles contract by sliding the thin and thick filaments along each other. Actomyosin motors are important in muscle contraction as well as other processes like retraction of membrane blebs, filiopod retraction, and uropodium advancement.
