Detailed explanation-1: -The correct option is C. external opening of the urinogenital duct. The urinary meatus, also known as the external urethral orifice, is the opening or meatus of the urethra. It is the point where urine exits the urethra in males and in females, and also where semen exits the urethra in males.
Detailed explanation-2: -Urethral meatus refers to the external opening of urinogenital duct, through which, in males, urine and semen both exits from the body.
Detailed explanation-3: -The external urethral orifice opens to the outside just anterior to the opening for the vagina. In males, the urethra is much longer, about 20 cm (7 to 8 inches) in length, and transports both urine and semen.
Detailed explanation-4: -The urethral meatus is slightly ventral to the tip of the penis. The bulbous urethra is invested in the bulb of the penis, the portion of corpus spongiosum that lies between the split corpora cavernosa in the superficial perineal space.
