Ligament Of Ovary
The ovarian ligament (also called the utero-ovarian ligament or proper ovarian ligament) is a fibrous ligament that connects the ovary to the lateral surface of the uterus. Structure The ovarian ligament is composed of muscular and fibrous tissue; it extends from the uterine extremity of the ovary to the lateral aspect of the uterus, just below the point where the uterine tube and uterus meet. The ligament runs in the broad ligament of the uterus, which is a fold of peritoneum rather than a fibrous ligament. Specifically, it is located in the parametrium. Development Embryologically, each ovary (which forms from the gonadal ridge) is connected to a band of mesoderm, the gubernaculum. This strip of mesoderm remains in connection with the ovary throughout its development, and eventually spans this distance by attachment within the labia majora. During the latter parts of urogenital development, the gubernaculum forms a long fibrous band of connective tissue stretching from the ...

Uterus
The uterus (from Latin ''uterus'', plural ''uteri'') or womb () is the organ in the reproductive system of most female mammals, including humans that accommodates the embryonic and fetal development of one or more embryos until birth. The uterus is a hormone-responsive sex organ that contains glands in its lining that secrete uterine milk for embryonic nourishment. In the human, the lower end of the uterus, is a narrow part known as the isthmus that connects to the cervix, leading to the vagina. The upper end, the body of the uterus, is connected to the fallopian tubes, at the uterine horns, and the rounded part above the openings to the fallopian tubes is the fundus. The connection of the uterine cavity with a fallopian tube is called the uterotubal junction. The fertilized egg is carried to the uterus along the fallopian tube. It will have divided on its journey to form a blastocyst that will implant itself into the lining of the uterus – the endometrium, where it will ...

Broad Ligament Of The Uterus
The broad ligament of the uterus is the wide fold of peritoneum that connects the sides of the uterus to the walls and floor of the pelvis. Structure Subdivisions Contents The contents of the broad ligament include the following: * Reproductive ** uterine tubes (or Fallopian tube) ** ovary (some sources consider the ovary to be on the broad ligament, but not in it.) * vessels ** ovarian artery (in the suspensory ligament) ** uterine artery (in reality, travels in the cardinal ligament) * ligaments ** ovarian ligament ** round ligament of uterus ** suspensory ligament of the ovary (Some sources consider it a part of the broad ligament, while other sources just consider it a "termination" of the ligament.) Relations The peritoneum surrounds the uterus like a flat sheet that folds over its fundus, covering it anteriorly and posteriorly; on the sides of the uterus, this sheet of peritoneum comes in direct contact with itself, forming the double layer of peritoneum known as ...

Ovarian Cancer
Ovarian cancer is a cancerous tumor of an ovary. It may originate from the ovary itself or more commonly from communicating nearby structures such as fallopian tubes or the inner lining of the abdomen. The ovary is made up of three different cell types including epithelial cells, germ cells, and stromal cells. When these cells become abnormal, they have the ability to divide and form tumors. These cells can also invade or spread to other parts of the body. When this process begins, there may be no or only vague symptoms. Symptoms become more noticeable as the cancer progresses. These symptoms may include bloating, vaginal bleeding, pelvic pain, abdominal swelling, constipation, and loss of appetite, among others. Common areas to which the cancer may spread include the lining of the abdomen, lymph nodes, lungs, and liver. The risk of ovarian cancer increases with age. Most cases of ovarian cancer develop after menopause. It is also more common in women who have ovulated m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uterine Horns
The uterine horns (cornua of uterus) are the points in the upper uterus where the fallopian tubes exit to meet the ovaries. They are one of the points of attachment for the round ligament of uterus (the other being the mons pubis). They also provide attachment to the ovarian ligament, which is located below the fallopian tube at the back; while the round ligament of uterus is located below the tube at the front. The uterine horns are far more prominent in other animals (such as cows and cats) than they are in humans. In the cat, implantation of the embryo occurs in one of the two uterine horns, not the body of the uterus itself. Occasionally, if a fallopian tube does not connect, the uterine horn will fill with blood each month, and a minor one-day surgery will be performed to remove it. Often, people who are born with this have trouble getting pregnant as both ovaries are functional and either may ovulate. The spare egg An egg is an organic vessel grown by an animal to ...

Ovary
The ovary is an organ in the female reproductive system that produces an ovum. When released, this travels down the fallopian tube into the uterus, where it may become fertilized by a sperm. There is an ovary () found on each side of the body. The ovaries also secrete hormones that play a role in the menstrual cycle and fertility. The ovary progresses through many stages beginning in the prenatal period through menopause. It is also an endocrine gland because of the various hormones that it secretes. Structure The ovaries are considered the female gonads. Each ovary is whitish in color and located alongside the lateral wall of the uterus in a region called the ovarian fossa. The ovarian fossa is the region that is bounded by the external iliac artery and in front of the ureter and the internal iliac artery. This area is about 4 cm x 3 cm x 2 cm in size.Daftary, Shirish; Chakravarti, Sudip (2011). Manual of Obstetrics, 3rd Edition. Elsevier. pp. 1-16. . The ovari ...

Round Ligament Of Uterus
The round ligament of the uterus is a ligament that connects the uterus to the labia majora. Structure The round ligament of the uterus originates at the uterine horns, in the parametrium. The round ligament exits the pelvis via the deep inguinal ring. It passes through the inguinal canal, and continues on to the labia majora. At the labia majora, its fibers spread and mix with the tissue of the mons pubis. Development The round ligament develops from the gubernaculum which attaches the gonad to the labioscrotal swellings in the embryo. Blood supply The round ligament is supplied by the artery of the round ligament of uterus, also known as ''Sampson's artery''. Function The function of the round ligament is maintenance of the anteversion of the uterus (a position where the fundus of the uterus is turned forward at the junction of cervix and vagina) during pregnancy. Normally, the cardinal ligament is what supports the uterine angle (angle of anteversion). When the uterus gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Labia Majora
The labia majora (singular: ''labium majus'') are two prominent longitudinal cutaneous folds that extend downward and backward from the mons pubis to the perineum. Together with the labia minora they form the labia of the vulva. The labia majora are homologous to the male scrotum. Etymology ''Labia majora'' is the Latin plural for big ("major") lips; the singular is ''labium majus.'' The Latin term ''labium/labia'' is used in anatomy for a number of usually paired parallel structures, but in English it is mostly applied to two pairs of parts of female external genitals (vulva)—labia majora and labia minora. Labia majora are commonly known as the outer lips, while labia minora (Latin for ''small lips''), which run alongside between them, are referred to as the inner lips. Traditionally, to avoid confusion with other lip-like structures of the body, the labia of female genitals were termed by anatomists in Latin as ''labia majora (''or ''minora) pudendi.''

Mesoderm
The mesoderm is the middle layer of the three germ layers that develops during gastrulation in the very early development of the embryo of most animals. The outer layer is the ectoderm, and the inner layer is the endoderm.Langman's Medical Embryology, 11th edition. 2010. The mesoderm forms mesenchyme, mesothelium, non-epithelial blood cells and coelomocytes. Mesothelium lines coeloms. Mesoderm forms the muscles in a process known as myogenesis, septa (cross-wise partitions) and mesenteries (length-wise partitions); and forms part of the gonads (the rest being the gametes). Myogenesis is specifically a function of mesenchyme. The mesoderm differentiates from the rest of the embryo through intercellular signaling, after which the mesoderm is polarized by an organizing center. The position of the organizing center is in turn determined by the regions in which beta-catenin is protected from degradation by GSK-3. Beta-catenin acts as a co-factor that alters the activity of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parametrium
The parametrium is the fibrous and fatty connective tissue that surrounds the uterus. This tissue separates the supravaginal portion of the cervix from the bladder. The parametrium lies in front of the cervix and extends laterally between the layers of the broad ligaments. It connects the uterus to other tissues in the pelvis. It is different from the perimetrium, which is the outermost layer of the uterus. The uterine artery and ovarian ligament are located in the parametrium. An associated form of pelvic inflammatory disease is inflammation of the parametrium known as parametritis Parametritis (also known as pelvic cellulitis) is an infection of the parametrium (connective tissue adjacent to the uterus The uterus (from Latin ''uterus'', plural ''uteri'') or womb () is the organ in the reproductive system of most female ....

Peritoneum
The peritoneum is the serous membrane forming the lining of the abdominal cavity or coelom in amniotes and some invertebrates, such as annelids. It covers most of the intra-abdominal (or coelomic) organs, and is composed of a layer of mesothelium supported by a thin layer of connective tissue. This peritoneal lining of the cavity supports many of the abdominal organs and serves as a conduit for their blood vessels, lymphatic vessels, and nerves. The abdominal cavity (the space bounded by the vertebrae, abdominal muscles, diaphragm, and pelvic floor) is different from the intraperitoneal space (located within the abdominal cavity but wrapped in peritoneum). The structures within the intraperitoneal space are called "intraperitoneal" (e.g., the stomach and intestines), the structures in the abdominal cavity that are located behind the intraperitoneal space are called "retroperitoneal" (e.g., the kidneys), and those structures below the intraperitoneal space are called "subp ...
