Place the events of excitation contraction coupling in order from the action potential being produced at the neuromuscular junction to finish.
a. Ca2+ diffuses out into the sarcoplasm
b.Ca2+ release channels in SR open
c. Action Potentials conducted along transverse tubules
d. AP opens voltage gated Ca2+ channels in T-tubules
e. Ca2+ binds to troponin beginning contraction

The junctional folds and sarcolemma serve as the starting point for the excitation-contraction coupling events, which then move on through the T tubules and sarcoplasmic reticulum before acting at the sarcomere.

What takes place when a muscle contracts?

  • Muscle contraction occurs when tension-producing areas within muscle cells are activated.
  • Muscle tension can be generated without a change in muscle length, such as while keeping a heavy object in place, hence muscle contraction does not always imply muscle shortening in physiology.
  • Actin and myosin filaments glide past one another to cause muscle contraction. It is generally accepted that cross-bridges that protrude from myosin filaments and engage in cyclic interactions with actin filaments when ATP is hydrolyzed are what propel this process.

  • Action Potentials carried out via transverse tubules are performed by Ca2+ release channels in SR.
  • Ca2+ spreads into the sarcoplasm.
  • Troponin binds to Ca2+ to start contraction.
  • AP activates voltage gated the T-tubules' Ca2+ channels
