Answer 2

A fully-developed Taenia Solium may attain a length of 3-5 metres. Its anteroposterior ends are clearly distinguishable but it is difficult to differentiate the dorsal from the ventral surface. The body is ribbon-like (Fig. 69A) and consists of a distinct head or scolex at the anterior region.

The tip of the head bears a conical elevation—the rostellum which can be retracted or extended. The rostellum bears 28 to 33 hooks arte of two types- larger and smaller and they alternate with each other. Each hook parts (fig 69B) has three a base or guard, a conical blade at the tip and a handle pro­jected from the middle.
