Document Summary
Tendon a cord of connective tissue connecting a muscle to bone/connective tissue. Skeletal muscle - organ composed of fibers of skeletal muscle tissue, epithelial tissue, connective tissue, and nervous tissue. Organized into units that contract, called sarcomeres. Sarcomere z-line proteins that border the sarcomere and support actin and titin filaments. Sarcomere i-band light band adjacent to the z-line in with only titin and actin filaments. Sarcomere m-line middle of the sarcomere composed of proteins that support myosin and titin filaments. Sarcomere a-band the dark band of overlapping actin and myosin and titin filaments. Sarcomere h-zone lighter band of myosin and titin filaments in the middle of the sarcomere between actin filaments, is in the a band. Thin actin filament thin filaments composed of actin protein subunits for structure of myosin. Thick actin filament- filament made of myosin protein subunits that have a head and tail in order to tails anchor the myosin to other myosin.
