Topic: Scolex


  
  Tapeworms - LoveToKnow 1911
The body, or " strobila," consists of a usually minute organ of attachment (scolex or its representative) which is imbedded in the intestinal membrane, and of a series of segments that arise from the base of the scolex and increase in size distally.
The scolex is biradially constructed, the proglottides flattened, quadrangular and bilaterally symmetrical.
This elaborate type of scolex appears to be an adaptation to grasp the spiral intestinal valve of sharks and rays.

 Olympus MIC-D: Darkfield Gallery - Tapeworm Scolex
The scolex at the anterior end of the cestode is a specialized body segment (or proglottid), which anchors the parasite to its host.
The scolex is usually covered with hooks or suckers and is used by helminth taxonomists as a key characteristic for identifying species of tapeworms.
Another hookless tapeworm featuring four suckers on its scolex, Hymenolepsis diminuta is primarily a rodent parasite that uses an arthropod intermediate host.

 Cestoda - Wikipedia, the free encyclopedia
All have a scolex, sometimes colloquially referred to as the "head," a "neck," and one or more proglottids, which are sometimes called "segments," and which are the source of the name "tapeworm," because they look like a strip of tape.
Cyclophyllid cestodes can be identified by the presence of four suckers on their scolex, though they may have other structures as well.
While the scolex is often the most distinctive part of an adult tapeworm, it is often unavailable in a clinical setting, as it is inside the patient.

An adult tapeworm consists of a knoblike head, or scolex, equipped with hooks for attaching to the intestinal wall of the host (which may be a human), a neck region, and a series of flat, rectangular body segments, or proglottids, generated by the neck.

If the scolex has not been killed by sufficient cooking of the meat, it sheds its covering and attaches to the intestinal wall, where it begins producing proglottids.

The difference between egg and scolex is this: an egg is that from a part of which the young comes into being, the rest being nutriment for it; but the whole of a scolex is developed into the whole of the young animal.
But we cannot say simply that all bloodless animals produce a scolex, for the classes overlap one another, (1) the insects, (2) the animals that produce a scolex, (3) those that lay their egg imperfect, as the scaly fishes, the crustacea, and the cephalopoda.
For insects produce a scolex first; the scolex after developing becomes egg-like (for the so-called chrysalis or pupa is equivalent to an egg); then from this it is that a perfect animal comes into being, reaching the end of its development in the second change.
