The ability of sperm cells to move along the ductus deferens is due to ________.
A) hormonal action
B) gravity
C) enzymatic activity
D) peristaltic contractions

Question

Quizplus · Accepted Answer

The ability of sperm cells to move along the ductus deferens is due to peristaltic contractions, which are rhythmic contractions of the smooth muscle in the walls of the ductus deferens. Hormonal action may affect the production of sperm, but it does not play a direct role in their movement along the ductus deferens. Gravity and enzymatic activity do not contribute to the movement of sperm cells through the ductus deferens.
