In higher organisms each muscle fibre is innervated by a single motor nerve fibre; in other species (e.g., crustaceans) inhibitory fibres are also present.

Where is calcium stored in the muscle cell? - Answers

WebTerminal cisternae are discrete regions within the muscle cell. They store calcium (increasing the capacity of the sarcoplasmic reticulum to release calcium) and release it when an action potential courses down the … WebThe muscle fiber will repolarize, which closes the gates in the SR where Ca ++ was being released. ATP-driven pumps will move Ca ++ out of the sarcoplasm back into the SR. This results in the “reshielding” of the actin-binding sites on the thin filaments. edtm webcam
