The thyristor is a four-layered, three terminal semiconductor device, with each layer consisting of alternately N-type or P-type material, for example P-N-P-N.n earlier gas filled tube device called a thyratron provided a similar electronic switching capability, where a small control voltage could switch a large current. It is from a combination of thyratron and  transistor  that the term thyristor is derived.
The endoplasmic reticulum is composed of sac-like structures called cisternae that are folded and bound together by a cytoskeleton. There are two types of endoplasmic reticulum: smooth endoplasmic reticulum and rough endoplasmic reticulum.Smooth endoplasmic reticulum gets its name from its smooth folded surface.efinition of Endoplasmic Reticulum. Cells have many organelles that work together to help them complete their life functions. One of those organelles is the endoplasmic reticulum, which is an interconnected network of membrane vesicles, or small containers used by cells to transport or hold materials.
