Title: What effect does the transmission of a muscle fiber action potential traveling to the sarcoplasmic reticulum..? Post by: JulieA on Sep 8, 2012 What effect does the transmission of a muscle fiber action potential traveling to the sarcoplasmic reticulum have on the pathway leading to muscle contraction?
A. The sarcoplasmic reticulum releases calcium into the cytoplasmic fluid surrounding the thin and thick filaments. B. It results in motor neurons firing multiple action potentials in rapid succession. C. It allows myosin heads to attach, flex, release, extend, and reattach as long as calcium is present. D. The calcium binds to actin-binding sites. Title: What effect does the transmission of a muscle fiber action potential traveling to the sarcoplasmic reticulum..?
