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.
Best Answer: The tricuspid valve has 3 leaflets, termed the anterior, the septal, and the posterior leaflet; all named for their anatomical position.The leaflets are connected to a respective papillary muscle, also bearing the same name respectively.he pulmonic valve also has 3 leaflets, or cusps as they are more often known as, which are termed the right, the left, and the anterior cusp. They also have corresponding papillary muscles of the same names, just like with the tricuspid valve. Source(s):
