What are the important parts of the scolex?

The scolex contains organs which facilitate attachment to the host tissue. Examples of this include suckers or hooks. The neck contains germinal cells which can give rise to new proglottids. Proglottids are individual segments of the strobilus and contain reproductive organs of both sexes.

What is the structure of a scolex?

The scolex contains the cephalic ganglion, or “brain,” of the tapeworm nervous system. Externally, the scolex is characterized by holdfast organs. Depending on the species, these organs consist of a rostellum, bothria, or acetabula.

What is attached to the scolex?

The tapeworm is attached to the intestinal wall with the scolex hooks and suckers. Gravid and egg-filled mature proglottids are being released from the posterior part of the worm and moved out in fecal mass.

What is the function of scolex?

The scolex (head) functions as an anchoring organ that attaches to intestinal mucosa. The neck is an unsegmented region with high regenerative capacity. If treatment does not eliminate the neck and scolex, the entire worm may regenerate. The rest of the worm consists of numerous proglottids (segments).

How can we differentiate Taenia saginata and Taenia solium eggs?

solium eggs stained entirely blue/purple in 4/18 cases and entirely magenta in one. Eggs of T. saginata were slightly larger and always ovoid, while T. solium eggs were smaller and were mostly spheric.

Is scolex posterior or anterior?

Modern zoology textbooks uniformly describe the scolex as the anterior end, but an opposite interpretation of the antero-posterior (AP) polarity of the tapeworm’s main body axis has sometimes been argued, beginning with Moniez in 1880 [5].

What structures on the scolex fasten the tapeworm to the intestinal wall?

The head of tapeworms, scolex, contains structures, such as grooves, suckers or hooks, which enable the worm to attach to the gut wall. The major part of the tapeworm is called strobila and it consists of segments, proglottids. They each contain both male and female reproductive organs.

Where is the scolex of a tapeworm?

The adult tapeworm has a scolex (head), a short neck, and a strobila (segmented body) formed of proglottids. Tapeworms anchor themselves to the inside of the intestine of their host using their scolex, which typically has hooks, suckers, or both. They have no mouth, but absorb nutrients directly from the host’s gut.

What are the parts of a tapeworm?

An adult tapeworm consists of a head, neck and chain of segments called proglottids. When you have an intestinal tapeworm infection, the tapeworm head adheres to the intestinal wall, and the proglottids grow and produce eggs.
