(1970) and Alexander et al. showed that nascent apoB-VLDL particles were present at smooth-surfaced terminal ends of the rough ER cisternae and, in some vesicles, in close proximity to the rough ER or interposed … Terminal 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 transverse tubules, eliciting muscle contraction. Because terminal cisternae ensure rapid calcium delivery, they are well developed in muscles that contract quickly, such as fast twitch skeletal muscle. Terminal cisternae then go on to release calcium, which binds to trop…
