Question

Quizplus · Accepted Answer

All of the listed options are involved in the processes of emission and ejaculation. Emission refers to the movement of semen from the testes and epididymis into the urethra, which is initiated by peristaltic contractions of the ampulla and requires sympathetic stimulation. Ejaculation, on the other hand, involves the forceful expulsion of semen from the urethra via contractions of the bulbospongiosus muscle, which propels the semen into the female reproductive tract during sexual intercourse. Therefore, all of the options listed are involved in emission and ejaculation.
