Question

Whipworm is named so because it's

• A. Anterior two-third is slender
• B. Posterior two-third is slender
• C. Anterior one third is slender
• D. Posterior one third is slender

Answer 1

The correct option is A Anterior two-third is slender

In adult Trichuris trichiura, the anterior portion of the body is long and slender, whereas the posterior portion widens abruptly and thickens, giving the worm the appearance of a bullwhip; hence, its common name “whipworm.” Males are slightly smaller than females, the latter measuring 30 to 50 mm in length. In both sexes, a capillary-like esophagus extends two-thirds of the body length and is encircled along much of its length by a series of unicellular glands, the stichocytes.

So, the correct answer is 'Anterior two-third is slender'.
