Question

Quizplus · Accepted Answer

T tubules (transverse tubules) are extensions of the sarcolemma that carry the nerve impulses deep into the sarcoplasm, allowing for coordinated contractions of the muscle fibers. Sarcolemma is the plasma membrane surrounding a muscle fiber. Myoglobin is a protein found in muscle cells that stores and transports oxygen. Sarcoplasmic reticulum is a specialized type of endoplasmic reticulum found in muscle cells that stores and releases calcium ions for muscle contraction.
