Ovarian Fossa
The ovarian fossa is a shallow depression on the lateral wall of the pelvis, where in the ovary lies. This ovarian fossa has the following boundaries: * superiorly: by the external iliac artery and vein * anteriorly and inferiorly: by the broad ligament of the uterus * posteriorly: by the ureter, internal iliac artery and vein * inferiorly: by the obturator nerve, artery and vein 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 b ...

Human Pelvis
The pelvis (plural pelves or pelvises) is the lower part of the Trunk (anatomy), trunk, between the human abdomen, abdomen and the thighs (sometimes also called pelvic region), together with its embedded skeleton (sometimes also called bony pelvis, or pelvic skeleton). The pelvic region of the trunk includes the bony pelvis, the pelvic cavity (the space enclosed by the bony pelvis), the pelvic floor, below the pelvic cavity, and the perineum, below the pelvic floor. The pelvic skeleton is formed in the area of the back, by the sacrum and the coccyx and anteriorly and to the left and right sides, by a pair of hip bones. The two hip bones connect the spine with the lower limbs. They are attached to the sacrum posteriorly, connected to each other anteriorly, and joined with the two femurs at the hip joints. The gap enclosed by the bony pelvis, called the pelvic cavity, is the section of the body underneath the abdomen and mainly consists of the reproductive organs (sex organs) and ...

Aortic Bifurcation
The aortic bifurcation is the point at which the abdominal aorta bifurcates (forks) into the left and right common iliac arteries. The aortic bifurcation is usually seen at the level of L4, just above the junction of the left and right common iliac veins. The right common iliac artery passes in front of the left common iliac vein. In some individual, mainly women with lumbar lordosis this vein can be compressed between the vertebra and the artery. This is the so-called Cockett syndrome or May–Thurner syndrome can cause a slower venous flow and the possibility of deep venous thrombosis in the left leg mainly in pregnancy. In surface anatomy, the bifurcation approximately corresponds to the umbilicus. Additional images Image:Gray531.png, The abdominal aorta and its branches.

Aorta
The aorta ( ) is the main and largest artery in the human body, originating from the left ventricle of the heart and extending down to the abdomen, where it splits into two smaller arteries (the common iliac arteries). The aorta distributes oxygenated blood to all parts of the body through the systemic circulation. Structure Sections In anatomical sources, the aorta is usually divided into sections. One way of classifying a part of the aorta is by anatomical compartment, where the thoracic aorta (or thoracic portion of the aorta) runs from the heart to the diaphragm. The aorta then continues downward as the abdominal aorta (or abdominal portion of the aorta) from the diaphragm to the aortic bifurcation. Another system divides the aorta with respect to its course and the direction of blood flow. In this system, the aorta starts as the ascending aorta, travels superiorly from the heart, and then makes a hairpin turn known as the aortic arch. Following the aortic arch ...

Common Iliac Artery
The common iliac artery is a large artery of the abdomen paired on each side. It originates from the aortic bifurcation at the level of the 4th lumbar vertebra. It ends in front of the sacroiliac joint, one on either side, and each bifurcates into the external and internal iliac arteries. Structure The common iliac artery are about 4 cm long in adults and more than a centimeter in diameter. It begins as a branch of the aorta. This is at the level of the 4th lumbar vertebra. It runs inferolaterally, along the medial border of the psoas muscles. It bifurcates into the external iliac artery and the internal iliac artery at the pelvic brim, in front of the sacroiliac joints. The common iliac artery, and all of its branches, exist as paired structures (that is to say, there is one on the left side and one on the right). The distribution of the common iliac artery is basically the pelvis and lower limb (as the femoral artery) on the corresponding side. Relations Both common il ...

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 ...

External Iliac Artery
The external iliac arteries are two major Artery, arteries which bifurcate off the common iliac arteries anterior to the sacroiliac joint of the pelvis. Structure The external iliac artery arises from the bifurcation of the common iliac artery. They proceed anterior and inferior along the medial border of the psoas major muscles. They exit the Pelvis, pelvic girdle posterior and inferior to the inguinal ligament. This occurs about one third laterally from the insertion point of the inguinal ligament on the pubic tubercle. At this point they are referred to as the femoral arteries. Branches Function The external iliac artery provides the main blood supply to the legs. It passes down along the brim of the pelvis and gives off two large branches - the "inferior epigastric artery" and a "deep circumflex artery." These vessels supply blood to the muscles and skin in the lower abdominal wall. The external iliac artery passes beneath the inguinal ligament in the lower part of the ...

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 ...

Ureter
The ureters are tubes made of smooth muscle that propel urine from the kidneys to the urinary bladder. In a human adult, the ureters are usually long and around in diameter. The ureter is lined by urothelial cells, a type of transitional epithelium, and has an additional smooth muscle layer that assists with peristalsis in its lowest third. The ureters can be affected by a number of diseases, including urinary tract infections and kidney stone. is when a ureter is narrowed, due to for example chronic inflammation. Congenital abnormalities that affect the ureters can include the development of two ureters on the same side or abnormally placed ureters. Additionally, reflux of urine from the bladder back up the ureters is a condition commonly seen in children. The ureters have been identified for at least two thousand years, with the word "ureter" stemming from the stem relating to urinating and seen in written records since at least the time of Hippocrates. It is, however, on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internal Iliac Artery
The internal iliac artery (formerly known as the hypogastric artery) is the main artery of the pelvis. Structure The internal iliac artery supplies the walls and viscera of the pelvis, the buttock, the reproductive organs, and the medial compartment of the thigh. The vesicular branches of the internal iliac arteries supply the bladder. It is a short, thick vessel, smaller than the external iliac artery, and about 3 to 4 cm in length. Course The internal iliac artery arises at the bifurcation of the common iliac artery, opposite the lumbosacral articulation, and, passing downward to the upper margin of the greater sciatic foramen, divides into two large trunks, an anterior and a posterior. It is posterior to the ureter, anterior to the internal iliac vein, anterior to the lumbosacral trunk, and anterior to the piriformis muscle. Near its origin, it is medial to the external iliac vein, which lies between it and the psoas major muscle. It is above the obturator nerve. Bra ...
