Question

Which muscle(s)of the pelvic floor is/are responsible for erection of the penis and clitoris?
A)Bulbospongiosus only
B)Superficial transverse perineal muscle and coccygeus
C)Ischiocavernosus only
D)Bulbospongiosus and ischiocavernosus
E)Coccygeus only

Accepted Answer

Both the bulbospongiosus and ischiocavernosus muscles are responsible for the erection of the penis and clitoris. The bulbospongiosus muscle compresses the bulb of the penis or clitoris during orgasm, while the ischiocavernosus muscle helps maintain the erection by compressing the base of the penis or clitoris to restrict blood flow.
