Sarcomere - Coggle Diagram
Sarcomere
Myofibril: Performs muscle contraction
Myofilament: Muscle proteins that make up a myofibril in a muscle fiber
Actin: Bead-shaped protein that has an area called active site that can bind to a myosin head.
Tropomyosin: protein involved in muscle contraction. It is related to myosin and occurs together with troponin in the thin filaments of muscle tissue
Troponin:group of proteins found in skeletal and heart (cardiac) muscle fibers that regulate muscular contraction
Myosin: Protein that forms together with actin and contractile filaments of muscle cells
Endomysium: tissue that surrounds individual muscle fibers
Epimysium: fibrous elastic tissue surrounding a muscle.
Perimysium: tissue that surrounds the fascicle
Muscle fiber: consist of a single muscle cell. They help to control the physical forces within the body. When grouped together, they can facilitate organized movement of your limbs and tissues
Muscle fascicle: bundle of skeletal muscle fibers surrounded by perimysium, a type of connective tissue
Muscle: band or bundle of fibrous tissue in a human or animal body that has the ability to contract, producing movement in or maintaining the position of parts of the body.
Sarcolemma: fine transparent tubular sheath which envelops the fibers of skeletal muscles.
Sarcomere: structural unit of a myofibril in striated muscle, consisting of a dark band and the nearer half of each adjacent pale band.
Sarcoplasm: cytoplasm of striated muscle cells
T-tubule: invaginations of the sarcolemma penetrating into the myocyte interior, forming a highly branched and interconnected network that makes junctions with the sarcoplasmic reticulum.
Sarcoplasmic reticulum: membrane-bound structure found within muscle cells that is similar to the endoplasmic reticulum in other cells. The main function of the SR is to store calcium ions
Dystrophin: protein found in skeletal muscle, which is absent in sufferers from muscular dystrophy
Titin: very large protein that contributes to the elasticity of striated muscle fibers.
I band: the lighter striation that contains thin filaments
Nebulin:
A band: darker striation that has thin and thick filaments overlapping each other
H zone: lighter section within the A band
M line: the line in middle of the H zone and A band.
ATP: Binds to myosin and has binding sites from myosin and actin
