In response to action potentials arriving along the transverse tubules, the sarcoplasmic reticulum releases

Question

Quizplus · Accepted Answer

Action potentials arriving along the transverse tubules open voltage-gated channels on the sarcoplasmic reticulum, causing it to release calcium ions into the cytoplasm. This calcium then allows for muscle contraction to occur by binding to the regulatory proteins on the thin filaments within the muscle fibers.
