Question

Syncytial epidermis is found in
A. Earthworm
B. Ascaris
C. Hydra
D. Starfish

Answer 1

Hint: Syncytial epidermis layer present in the organisms known as “Ascaris”. The epidermis characteristic had a “phylum aschelminthes” and body fully covered with a cuticle in a thick layer. Cilla is absent in the phylum.

Complete answer:
The “phylum aschelminthes” also called as “Nemathelminthes".Syncytial epidermis composed of peripheral layer of continuous cytoplasm is feature found in the parasitic platyhelminth part of the cytoarchitectural.The protection and help to provide nutrients acquisition, cestodes by completely lack of gastrointestinal tract by helminth epidermis and absorb all nutritive material through the tegument. Cestode tegument resemblance to the mucosal epithelium of the vertebrates small intestine present on the surface of the ecto cytoplasm including the possession of a microvillus. The helminth epidermis present in the cytoskeleton found very little in the contrast to the intestinal epithelial cell. To detect the tegument of the tapeworm hymenolepis diminuta using different microscopically techniques for the presence and distribution of microtubules, filaments and microfilaments. It is restricted to specific locations along the plasmalemma of the ecto cytoplasm but found that both intermediate sized and actin containing microfilaments. Microtubules concentrated in the supranuclear region of the cytoplasmic brides and perikarya found throughout the tegument present in it. Some epithelial lack of filamentous terminal web unlike the brush borders and attached with the microtubules.

Therefore the correct option is (Ascaris).

Note: Ascaris that parasitize the human intestine nematodes (roundworms) are very large adult males 15to 30 cm and females 20 to 35 cm. Ascaris derived from the pigs but the primary species involved in the human infections was A. lumbricoides. The hybrids have been identified for the two parasites are very closely related and reproductively isolated species is a contentious topic.
