Final answer:
The bulbocavernosus muscle aids in ejaculation in males and vaginal contraction during orgasm in females. It also plays a role in urination control for both sexes.
The correct answer is B) Male: Ejaculation; Female: Orgasm
Step-by-step explanation:
In males, the bulbocavernosus muscle (also known as the bulbospongiosus) is involved in sexual function. During the process of ejaculation, this muscle facilitates the expulsion of semen by contracting rhythmically. In contrast, in females, the bulbocavernosus muscle contributes to the contraction of the vagina. Particularly, this muscle plays a significant role during orgasm, where it contracts, similarly aiding in sexual function and pleasure.
The functions of the bulbocavernosus in both genders relate to the sexual reproductive systems. In males, this includes aiding in ejaculation and potentially contributing to sensations during sexual activity, while in females, the muscle supports vaginal contraction which can be particularly noticeable during orgasm. Furthermore, in both sexes, the perineum muscles, which include the bulbocavernosus, aid in urination control.
