Questions and Answers
  • 1. 

    The ability of sperm cells to move along the ductus deferens is due to ____________.

    • A.

      Gravity

    • B.

      Peristaltic contractions

    • C.

      Enzymatic activity

    • D.

      Hormonal action

    Correct Answer
    B. Peristaltic contractions
    Explanation
    The ability of sperm cells to move along the ductus deferens is due to peristaltic contractions. Peristaltic contractions are rhythmic, wave-like muscle contractions that propel substances through tubes or ducts in the body. In the case of the ductus deferens, these contractions help to propel sperm cells from the testes towards the urethra, allowing them to eventually be ejaculated during sexual intercourse. Gravity, enzymatic activity, and hormonal action do not play a direct role in the movement of sperm cells along the ductus deferens.
