What is actin? Actin is a thin protein filament in muscle fibers that works with myosin for muscle contraction. What is myosin? Myosin is a thick protein filament in muscle fibers that interacts with actin to cause muscle contraction. What is a sarcomere? A sarcomere is the basic contracting unit in a muscle fiber, made of actin and myosin. What is troponin? Troponin is a protein on actin filaments; it binds calcium and helps start muscle contraction. What is the sarcoplasmic reticulum? ...

Components of myofibrils myosin- thick filament, with head , rsponsible for splitting ATP providing energy for the power stroke to grab onto the actin actin- thin filament, double helix troponin in actinbinds with Ca2+ from SR, exposes binding site on myosin to form cross bridges Crircular muscle structure arranged in a concentric ring Convergent muscle structure broad origin leading to a fan shaped muscle, looks similar to a brush or duster Parallell or longitudinal muscle structu...

Skeletal muscle - an organ specialized for contraction, composed of striated muscle fibers (cells), supported by connective tissue, attached to bone by a tendon or aponeurosis, and stimulated by somatic motor neurons Sarcomere - any of the repeating structural units of striated muscle Sliding filament mechanism - the explanation of how thick and thin filaments slide relative to one another during striated muscle contract to decrease sarcomere length Insertion - the attachment of a muscle t...
