What is the process of excitation-contraction coupling in skeletal muscle?

First coined by Alexander Sandow in 1952, the term excitation-contraction coupling (ECC) describes the rapid communication between electrical events occurring in the plasma membrane of skeletal muscle fibres and Ca2+ release from the SR, which leads to contraction.

What are the steps of muscle excitation?

Terms in this set (6)

1. Action potential spread along the sarcolemma to the T-tubules (transverse tubules)
2. Calcium is released into the sarcoplasmic reticulum (S.R.)
3. Calcium binds to actin and the blocking action of the tropomyosin is removed.
4. Myosin heads attach to begin contraction.

What are the 5 steps of skeletal muscle contraction?

Terms in this set (5)

• exposure of active sites – Ca2+ binds to troponin receptors.
• Formation of cross-bridges – myosin interacts with actin.
• pivoting of myosin heads.
• detachment of cross-bridges.
• reactivation of myosin.

How many steps are in excitation-contraction coupling?
