Anatomy and physiology of female reproductive system
Vagina
Defination
Vagina is a muscular tube that connects the vestibule with the uterus and serve as the entrance to the reproductive tract.
Anatomy
The outer walls of the anterior and posterior vagina are formed into longitudinal columns and superior portion of the vagina which is called fornix that meets the protruding uterine cervix.
The walls of the vagina are lined with the outer fibrous adventitia, middle layer of smooth muscle and inner mucous membrane with transverse folds called rugae.
The thin perforated hymen can partially surround the opening of the vaginal a orifice.
Lactobacilli produce lactic acid serves vagina as a self cleansing organ.
Physiology
The inner and middle layers allows the vagina to stretch to accommodate intercourse and birth.
The bartholins glands and lesser vestibular glands secrete mucus which keeps the vestibular area moist.
Vagina also serve as excretory duct for menstrual flow.
Vulva
Defination
Vulva is the external genitalia of the reproductive tract located immediately external to the genital orifice.
Anatomy
The vulva consist of all the structures externally visible from pubis to the perineum.
It includes the labia major and minora, mons pubis, clitos, bulb of vestibule, vulva vestibule, vestibular glands and genital orifice.
The mons pubis is the fatty cushion over the public bone it protects the public bone.
The clitos is a small erectile body beneath the mons pubis, it has an abundant blood and nerve supply.
The labia majora are the two folds of adipose tissue that conceal the underlying structures in a nullipara.
The labia minora are two thin, hairless folds that lie between the labia majora, they're richly supplied with blood vessels and nerves.
The vestibule is an almond shaped area bordered by the labia minora, and stretches from the fourchette posteriorly to the clitoris anteriorly.
Physiology
The labia minora serve to protect the female urethra and the entrance to the female reproductive tract.
Clitoris responsible for sexual sensation and orgasm.
Hymen is a thin membrane that temporarily covers the vagina
