Myofibrils consist of which proteins

WebFeb 9, 2024 · The cytoplasm is filled with myofibrils, which consist of sarcomeres arranged in series and bordered by Z disks (Z). The lower panel shows a scheme of two adjacent sarcomeres with thick (myosin) and thin (actin) filaments. Z disks are connected by transversally oriented desmin filaments (D). WebMyofibrils are contractile units (within the muscle cell) that consist of an ordered arrangement of longitudinal myofilaments (thin actin filaments and thick myosin filaments). The characteristic 'striations' of skeletal muscle readily observable by light microscopy are the thin filaments (light) the thick filaments (dark).
