Knowing oneself and the enemy, women are invincible in all battles. Only by understanding themselves can they receive scientific health care and fight against diseases and aging. The female reproductive organs are much more complex than the male reproductive organs, and many women are not very clear about their own structure. The female reproductive organs are composed of two parts: the external genitalia and the internal genitalia.
What are the organizational structures and functions of female genitalia
The external genitalia refers to the exposed part of the reproductive organs, also known as the external genitalia, including the pubic mound, large * *, small * *, * *, vestibular gland, urethral opening, and * * opening.
(1) Pudendal caruncle: It is a fat cushion covering the front and upper part of the pubic symphysis. There is * * on the pudendal caruncle of adult women, and it is distributed in an inverted triangle.
(2) Da * *: refers to the skin folds extending downwards on both sides of the pubic mound, which fuse in front of the perineal body below. Contains fat, connective tissue, and venous plexus.
(3) Small * *: On the inner side of the large * *, there are two thin folds, with many sebaceous glands and a moist surface. Rich in nerves and blood vessels, with sensitive sensations.
(4) * *: It is a cylindrical erectile tissue located at the top of the small * * on both sides, equivalent to a male * *, rich in nerves and blood vessels, and has a sharp sensation.
(5) * * Vestible: A rhombic area between two small * *, with a urethral opening in the front and a * * opening in the rear** There are mucosal folds around the mouth, called "hymen". The hymen usually ruptures during the first sexual life, but it can also be ruptured by intense exercise and trauma.
(6) The vestibular gland, also known as the Pasteurian gland, is located on both sides of the mouth below the vestibule and secretes mucus for lubrication during sexual impulse.
(7) Perineal: A soft tissue segment between the * * mouth and anus, composed of skin, muscles, and fascia, that supports pelvic organs.
The internal genitalia includes * *, uterus, fallopian tubes, and ovaries, often referred to as accessories.
(1) * * is a * * organ and a channel for menstrual blood discharge and fetal delivery. It is a flat tubular shape, narrow on the outside and wide on the inside, with a protruding cervix at the top** The front wall is approximately 7-9cm long, and the rear wall is approximately 10-12cm long** The mucosa has many folds and great extensibility. Mucosal cells contain glycogen, which is decomposed by * * bacteria to produce lactic acid, maintaining a certain acidity and preventing the proliferation of pathogenic bacteria.
(2) Uterus: The organ that produces menstruation and gives birth to a fetus, located in the center of the pelvic cavity, shaped like an inverted pear and slightly flattened in front and back. The lower third of the uterus is called the "cervix", and the lower half of the cervix extends into and opens at * *. The uterine wall consists of three layers: the serous layer, the muscular layer, and the mucous membrane (i.e. the endometrium) from the outside to the inside. Starting from adolescence, influenced by ovarian hormones, the endometrium undergoes periodic proliferation, secretion, and shedding, leading to the formation of menstruation.
(3) Fallopian tubes: located on both sides of the uterine floor, approximately 8-14cm long, opening in the abdominal cavity. It is an organ for transporting eggs, and also a place where eggs and sperm combine to form zygote. (4) Ovary: It is the female gonad that can produce eggs and secrete sex hormones. The ovaries are flat and elliptical, with one on each side. In adult women, the ovaries are approximately 4 × three × 1 centimeter in size.
