Scolex
Scolex
Scolex (pronounced: /ˈskoʊlɛks/), also known as the head of a tapeworm, is a structure found at the anterior end of the worm. The term originates from the Greek word "σκώληξ", meaning worm.
Anatomy
The scolex is the point of attachment for the tapeworm. It is typically equipped with hooks, suckers, or both, which it uses to attach itself to the intestinal wall of its host. The scolex may also have structures called rostellum and bothria, which aid in attachment.
Function
The primary function of the scolex is to anchor the tapeworm to the host's intestinal wall. From the scolex, the rest of the tapeworm, known as the strobila, grows. The strobila consists of a series of segments, or proglottids, which contain reproductive organs and produce eggs.
