Answer 1

In females, the urethra opens:

Answer: between the clit*ris and the vag*na.

Explanation: Urethra is a tubular structure carrying urine from the urinary bladder to the urethral meatus through which urine is removed from the body. In females, the urethra is shorter as compared to the males. It is around 4.5-5.0 cm in length. In females, the urethra carries only the urine whereas in males the urethra carries both urine and sperms. The urethra in females opens between the clit*ris and the vag*na.

Question 17.

The labia majora develops from the same source as the scr*tum in males.

Explanation: The labia majora is a pair of skin folds which extends from the mons pubis (mass of fatty tissues over the pubic symphysis) to the perineum (space between an*s and the vulva). It is homologous to the scr*tum males. Both labia majora and scr*tum develops from the labioscrotal fold of the developing embryo. Labia majora has the function of protection of delicate internal parts of female urogenital system like urethra orifice, vaginal orifice, clit*ris, labia minora.
