Structure of uterus

• Mons pubis: an anterior thick skin fold, having a collection of subcutaneous fat, hairy. • Labia majora: two rounded thick skin folds, one on each side. The space between these folds is called the pudendal cleft. These skin folds have a hairy outer surface and Inner surface devoid of hair. They enclose an abundant amount of adipose tissue and a thin layer of • Labia minora: Two thin skin folds, one on each side, The space between these folds is called the vestibule of the vagina, They lack hair follicles but they have numerous sebaceous glands, They enclose a core of loose • Clitoris: is an erectile structure covered by stratified squamous epithelium and supported by a lamina propria rich in It resembles the penis in male. It is in the anterior part of the pudendal cleft. It consists of 2 corpora cavernosa (forming the body of the clitoris) which enlarge anteriorly to form the glans clitoris. • Urethral orifice: it lies between the glans clitoris anteriorly and vaginal orifice posteriorly. • Vaginal orifice. it lies posterior to the urethral orifice.

The uterus is an organ in the lower belly (abdomen) or pelvis. It is part of the female reproductive system. It's where a baby grows. It's sometimes called the womb. The uterus is hollow andpear-shaped. It is about the size of a fist. It's in your lower belly (pelvic area). Your uterus is connected to the fallopian tubes. These tubes help carryeggs from the ovaries into the uterus. The lower part of the uterus connects to the vagina and is called the cervix. The wider, upper part of the uterus is called the corpus or fundus. The uterus has 3 layers: • Endometrium. This isthe inner lining. It's shed during a menstrual period. • Myometrium. This isthe thick middle muscle layer of the corpus or fundus. It expands during pregnancy to hold the growing baby. It contracts during labor to push the baby out. • Serosa. This is the smooth outer layer. It covers the uterus and makes it easy for the uterus to slide and move within the pelvis as needed. In people who still have their periods,1 ovaryreleases an egg intoa fallopian tube each month. During this time, the endometriumbecomes thicker to prepare for a fertilized egg. The egg enters the uterus. If it isn’t fertilized, it leaves the uterus through the vagina, and the endometrial lining is shed during a menstrual period. If the egg joins with a sperm cell (from a male),this fertilized egg attaches to the endometrium. The thick wall of the uterus protects the growing baby during pregnancy. During labor, the cervix opens (dilates)....

The Uterine structure The The uterus does not lie in line with the vagina but is usually turned forward (anteverted) to form approximately a right angle with it. The position of the uterus is affected by the amount of distension in the The cavity of the uterus is remarkably small in comparison with the size of the organ. Except during pregnancy, the cavity is flattened, with front and rear walls touching, and is triangular. The triangle is inverted, with its base at the top, between the openings of the two fallopian tubes, and with its apex at the isthmus of the uterus, the opening into the cervix. The canal of the cervix is flattened from front to back and is somewhat larger in its middle part. It is nabothian cysts) are found in the cervical mucous membrane. It is from this region that cervical The uterus is composed of three layers of tissue.

Function What does a uterus do? Your uterus plays a key role in your reproductive health and function. The three main jobs of your uterus are: • Pregnancy: Your uterus stretches to grow your baby during pregnancy. It can also contract to help push your baby out of your vagina. • Fertility: Your uterus is where a fertilized egg implants during • Menstrual cycle: Your uterine lining is where blood and tissue come from during menstruation. What happens to your uterus during menstruation? During your menstrual cycle, the lining of your uterus goes through several changes. The lining (called the endometrial lining) gets thicker and rich with blood as you near ovulation (releasing an egg from the ovaries). If an egg is fertilized during that cycle, it implants into the lining of your uterus, and pregnancy begins. Your endometrial lining sheds if pregnancy doesn’t happen (this is your period). This process repeats every menstrual cycle unless pregnancy occurs. What happens to your uterus during pregnancy? If conception (when the egg is fertilized by sperm) occurs during your menstrual cycle, the fertilized egg implants into your uterine lining. The fertilized egg (called a blastocyte) burrows into the endometrial lining of your uterus (implantation). This is when pregnancy officially begins, and you miss your menstrual period. Your uterus grows and stretches like a balloon to accommodate your growing baby. It contracts during labor and delivery to help push your baby out of your ...

Synonyms: Mucous membrane of uterus, Tunica mucosa uteri The The endometrium (also known as the mucosal layer or membrane) is the innermost layer of the uterus. It is composed of the • The basal layer - is composed mainly of stem cells that serve to regenerate the functional layer. • The functional layer - is adjacent to the uterine cavity and is lined by a single layer of The main function of the endometrium is to prepare the optimal environment for the implantation of the embryo. In addition, this layer prevents the adhesions between the opposed walls of the myometrium and maintains the patency of the uterine cavity.
