actin and myosin
Actin & Myosin compose myofibrils.
actin and myosin
thick filaments and thin filaments
sarcomeres are composed of myofilaments
Thin filaments consist primarily of the protein actin, coiled with nebulin filaments. Thick filaments consist primarily of the protein myosin, held in place by tit in filaments.
Myofibrils are made up of actin (thin filaments) and myosin (thick filaments).
The sarcoplasmic reticulum are the membranous interconnecting channels and sacs that surround and run parallel to the myofibrils.
