Question

Fasciola attaches itself to walls of the ducts by means of

• A. Anterior sucker
• B. Adhesive zone
• C. Posterior sucker/acetabulum
• D. Spiny cuticle and posterior sucker

Answer 1

The correct option is D Spiny cuticle and posterior sucker

Fasciola hepatica is one of the largest flukes in the world. The adult worm has a leaf shape with the anterior end being broader than the posterior end and an anterior cone-shaped projection {spiny cuticles}. The fluke possesses a powerful oral sucker at the end the anterior cone and a ventral sucker at the base of the cone which allows it to attach to the lining of the bile ducts. So, option D is correct.
