Quizplus · Accepted Answer

The functional unit of a skeletal muscle is called a sarcomere, which is defined as the segment between two Z discs. A myofibril is a thread-like structure that makes up the muscle fiber and contains sarcomeres. The sarcoplasmic reticulum is a specialized form of endoplasmic reticulum that stores calcium ions and plays a role in muscle contraction. A myofilament is a protein filament that makes up the sarcomere and includes actin and myosin.
