B Labia majora
The mons pubis is the prominence of subcutaneous tissue covered by stratified squamous epithelium overlying the female pubic symphysis. The labia majora are two large folds of skin that extend posteriorly from the mons pubis. These form the lateral boundaries of the vaginal opening and are covered with hair on the exterior surface, but are devoid of hair on the smooth inner surface. Sebaceous and sweat glands are associated with each surface and the folds contain various amounts of subcutaneous adipose tissue.
The labia majora are homologous to the skin of the scrotum in the male. The labia minora are smaller, paired folds of skin that underlie the labia majora and boarder the vaginal vestibule. These hairless folds of skin have a core of richly vascularized connective tissue and possess large sebaceous glands.
The clitoris is homologous to the penis and consists of erectile tissue covered by stratified squamous epithelium. Similar to the structure of the penis, the body of the clitoris is composed of paired erectile bodies referred to as corpora cavernosa. The clitoris ends with a small, round tubercle of tissue called the glans clitoris. The vestibule represents the opening of the vagina and is lined with stratified squamous epithelium. Vestibular glands are present in the underlying connective tissue, and provide mucus secretions near the vaginal opening.
