Question

Which of these do not show ciliary movement?

(a) Inner lining of trachea

(b) Oviducts

(c) Vasa efferentia

(d) Vas deferens

The question was posed to me by my school principal while I was bunking the class.

I'm obligated to ask this question of Types of Movement in chapter Locomotion and Movement of Biology – Class 11

Answer 1

Right option is (d) Vas deferens

The explanation is: The ciliated epithelium of the inner surface of the trachea, the movement of ova through the oviducts and the vasa efferentia show ciliary movement. The vas deferens does not show ciliary movement.
