Uterine Venous Plexus
The uterine plexuses lie along the sides and superior angles of the uterus between the two layers of the broad ligament, and communicate with the ovarian 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. T ... and vaginal plexuses. They are drained by a pair of uterine veins on either side: these arise from the lower part of the plexuses, opposite the external orifice of the uterus, and open into the corresponding hypogastric vein. Vasopressors, vasoconstrictor medications may be prescribed to alleviate the associated discomfort by shrinking the affected vein. References Veins of the torso Uterus {{circulatory-stub ...

Uterine Veins
The uterine vein is a vein of the uterus. It is found in the cardinal ligament. It drains into the internal iliac vein. It follows a similar course to the uterine artery. It helps to drain blood from the uterus, and removes waste from blood in the placenta during pregnancy. Structure The uterine vein is found in the cardinal ligament of the uterus. It travels through the broad ligament of the uterus to the lateral abdominal wall. It drains into the internal iliac vein. The uterine vein forms a venous plexus around the cervix. It follows a similar course to the uterine artery. Lymphatic vessels are associated with it. It also anastomoses with the ovarian vein. It may anastomose with the vaginal venous plexus. Function The uterine vein helps to drain blood from the uterus. This is also important for the removal of waste from blood in the placenta during pregnancy. Clinical significance Placenta measurement Measurements of the partial pressure of O2 in the uterine vein ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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
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 (uterus), 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 perito ...

Ovarian
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 ovarie ...

Uterovaginal Plexus (nerves)
The Uterovaginal plexus is a division of the inferior hypogastric plexus. In older texts, it is referred to as two structures, the "vaginal plexus" and "uterine plexus". * The ''Vaginal Plexus'' arises from the lower part of the pelvic plexus. It is distributed to the walls of the vagina, to the erectile tissue of the vestibule, and to the cavernous nerves of the clitoris. The nerves composing this plexus contain, like the vesical, a large proportion of spinal nerve fibers. * The ''Uterine Plexus'' accompanies the uterine artery to the side of the uterus, between the layers of the broad ligament; it communicates with the ovarian plexus The ovarian plexus arises from the renal plexus, and is distributed to the ovary, and fundus of the uterus. It is carried in the suspensory ligament of the ovary. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Veins Of The Torso
Veins are blood vessels in humans and most other animals that carry blood towards the heart. Most veins carry deoxygenated blood from the tissues back to the heart; exceptions are the pulmonary and umbilical veins, both of which carry oxygenated blood to the heart. In contrast to veins, arteries carry blood away from the heart. Veins are less muscular than arteries and are often closer to the skin. There are valves (called ''pocket valves'') in most veins to prevent backflow. Structure Veins are present throughout the body as tubes that carry blood back to the heart. Veins are classified in a number of ways, including superficial vs. deep, pulmonary vs. systemic, and large vs. small. * Superficial veins are those closer to the surface of the body, and have no corresponding arteries. *Deep veins are deeper in the body and have corresponding arteries. *Perforator veins drain from the superficial to the deep veins. These are usually referred to in the lower limbs and feet. *Communic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
