Fallopian tube which side

These nodules make it more difficult for eggs to pass through the tubes and increase the risk of ectopic pregnancy. They also reduce fertility. In contrast, non-nodular salpingitis just called salpingitis is usually caused by an infection, such as those associated with pelvic inflammatory disease.

Either acute or chronic salpingitis can also cause tubal blockages and scarring, but not the characteristic nodules of salpingitis isthmica nodosa.

Tubal infertility is a generic term that describes when someone is unable to conceive a pregnancy due to issues with their fallopian tubes. It may be due to a number of causes, from congenital abnormalities to infectious complications. One of the most common causes of tubal factor infertility is complications of chlamydia.

Tubal factor infertility is responsible for a large portion of cases of female infertility. Tubal torsion, or adnexal torsion, occurs when the fallopian tube gets twisted, possibly affecting its blood supply. Although this usually happens alongside ovarian torsion, it can happen on its own. Left untreated, tubal torsion can affect fertility. Hydrosalpinx describes when one or both fallopian tubes become swollen and filled with fluid. This can be the result of an infection. It can also be caused by an obstruction of one or both ends of the fallopian tube.

Primary cancer of the fallopian tube is very rare, but can happen. Less than 1 percent of gynecologic cancers are thought to originate in the fallopian tubes.

Fallopian tube metastases can also occur from non-gynecologic cancers. A hysterosalpingogram is a special type of X-ray used to examine the fallopian tubes. During this text, dye is injected through the cervix.

That dye flows through the uterus and into the fallopian tubes. Then an X-ray takes a picture of the dye-filled organs to look for any blockages or problems. Ideally, the hysterosalpingogram will show that fluid can flow easily through the tubes. If not, there may be issues with fertility. This test is done as an outpatient procedure. Laparoscopy is a type of surgery that can be used to examine the reproductive organs.

Small incisions are made and a camera is inserted into the abdomen. This allows the doctor to physically see the outside of the fallopian tubes and whether there appear to be any blockages or damage. This type of surgery is often referred to as minimally invasive surgery. It has the advantage that if abnormalities are found during the procedure, the doctor may be able to treat them immediately. Salpingoscopy involves inserting a rigid or flexible scope into the fallopian tubes.

This allows the doctor to visualize the inside of the tubes. They can check for narrowing or blockages. They can also see how fluid is moving through the tubes. This can be performed during a laparoscopic procedure. Salpingoscopy can also be used to treat tubal pregnancy.

Primary fallopian tube carcinoma. The collecting system of the uterine lymphatics is formed from anastomoses of a lateral-uterine descending network of lymph vessels which unites with collecting vessels from the utero-ovarian pedicle and the external iliac area.

Lymphatic drainage of the uterus and upper two-thirds of the vagina is primarily to the obturator and internal and external iliac nodes. The fallopian tubes are bilateral muscular structures of paramesonephric duct origin.

They are from 7 to 12 cm in length and usually less than 1 cm in diameter. The tubes or oviducts have a lumen that varies considerably in diameter. It is extremely narrow, being less than 1 mm at its opening into the uterine cavity. It is wider in the isthmus Fig. The tube begins in the uterine cavity at the cornu and penetrates the myometrium intramural or interstitial portion. The second portion is the relatively straight and narrow portion of the tube which emerges from the uterus posterior to and a little above the origin of the round ligament.

The lumen of the narrow isthmus is relatively simple, with a few longitudinal folds. This portion of its tube is 2 or 3 cm long.

There are three layers of musculature: the inner longitudinal, the middle circular layer, and the outer longitudinal layer. There is some evidence that the isthmus may act as a sphincter. Photomicrograph showing the isthmic portion of the fallopian tube; it is in this portion of the tube that spasm may occur and close the lumen.

The mucosa is lined by columnar epithelium which surrounds the lumen. The columnar cells have cilia. The circular muscle layer is thickest at the isthmus and thinnest at the infundibulum. Photomicrograph low power of the ampullary portion of the fallopian tube. The mucosa forms folds which in transsection of the tube simulate glandular structures. There are, however, no true secreting glands in the oviduct. The ampulla is the largest and longest portion of the tube, approximately 5 cm or more in length.

The lumen enlarges from 1 or 2 mm near the isthmus to over a centimeter at the distal portion. The mucosa has multiple longitudinal folds. The ampulla is the portion usually involved in gonorrheal salpingitis and tubo-ovarian abscesses and is the site of most ectopic pregnancies. At the distal end of the tube is the trumpet shaped infundibulum.

The tube ends in a number of fimbriae or frond-like projections; the largest of these is ordinarily in contact with the ovary and is known as the ovarian fimbria. The peritoneal cavity in the female is connected with the exterior of the body through the patent distal end of the tube by way of the uterus and vagina. This opening is of considerable clinical importance as blood, ascending infections, or pus can pass out of the tube to invade the abdominal cavity, with resultant pain, endometriosis, or pelvic infection.

The epithelial lining of the tube has been studied extensively by light and electron microscopy. On light microscopic examination, four types of cells can be readily seen. Secretory cells or nonciliated cells have a heavily granular cytoplasm and an oval nucleus. The ciliated cells have fine granular cytoplasms and are relatively square with large round nuclei. Pauerstein 4 has reviewed and summarized the numerous studies on tubal ultrastructure.

Two basic cell types have been described, ciliated and secretory. The ciliated cells have a clear cytoplasm with vesicular reticulum. Microvilli are seen extending from the luminal edge of the cell. The cilia themselves have two central filaments and nine double, lateral filaments.

Secretory cells have a dark cytoplasm with fine granules. Darker secretory granules are prominent, with irregularly distributed endoplasmic reticulum. The tubal epithelium is responsive to the estrogen and progesterone levels during the menstrual cycle, pregnancy, and the menopause. The proliferative phase is characterized by elevated epithelium with ciliated and secretory cells of equal height.

The luteal phase shows lower ciliated cells with higher and more prominent cytoplasm, sometimes with rupture and extrusion of the cytoplasm into the lumen. During menstruation and post-menstruation, cells are lower and smaller. During pregnancy, tubal epithelium remains low. There is considerable variation in postmenopausal changes in the tubal epithelium. Apparently significant secretory activity ceases, but the onset of atrophy is variable and deciliation may not occur until years after the menopause.

The principal blood supply of the tube is from the upper end of the uterine artery, which bifurcates and sends a large branch or ramus below the tube to anastomose with the ovarian artery. The proximal two-thirds of the tube is chiefly supplied by the uterine artery.

The arterial supply is quite variable and there may be three branches medial, intermediate, and lateral or a branch from the uterine and another from the ovarian artery. Anastomoses between uterine and ovarian arteries in the mesosalpinx are variable but always present. The venous system accompanies the arterial distribution. Capillary networks are to be found in subserosal, muscularis, and mucosal layers. The arrangement varies in different portions of the tube, but the venous plexuses become confluent in the subserosal layer.

The lymphatic drainage runs along the upper edge of the broad ligament to the lymphatic network below the hilus of the ovary. From here the flow from uterus, tube, and ovary drains to the para-aortic or lumbar nodes. The tube is provided with both sympathetic and parasympathetic innervation.

Sympathetic fibers from T10 through L2 reach the inferior mesenteric plexus. Postganglionic fibers then pass to the oviduct. The fibers from the inferior mesenteric plexus pass to the cervicovaginal plexus, which in turn sends fibers to the isthmus and part of the ampulla.

Some sympathetic fibers from T10 and T11 reach the celiac plexus and provide postganglionic fibers to the ovarian plexus, which supplies the distal ampulla and fimbriae. The parasympathetic supply is by vagal fibers from the ovarian plexus supplying the distal portion of the tube.

Part of the isthmus receives its parasympathetic supply from S2, S3, and S4 via the pelvic nerve and the pelvic plexuses. The sympathetic innervation of the female pelvis is depicted in Fig. Diagram of the sympathetic connections in the female pelvis, viewed from the front and above.

In the early embryo, differentiation of gonadal tissue occurs anterior to the mesonephros and along the entire medial aspect of the urogenital ridge.

The cranial portions of the gonadal ridge degenerate, leaving an indifferent genital gland near the mesonephros. Primitive germ cells originate in the epithelial lining of the dorsal part of the hindgut. They migrate to the gonad and are seen as radial strands extending into the mesenchymal tissue.

The migrating cells consist of primordial egg cells and prospective granulosa cells Fig. Photomicrograph low power of the cortex of the ovary of a human infant. The cortex of the ovary has numerous primordial germ cells with relatively little stroma.

The ovarian stroma is more abundant in the medulla, where the larger follicles are seen. The glistening white ovaries are generally oval in shape but may vary in size, position, and appearance, depending on the age and the reproductive activities of the individual.

The ovaries of a normal adult woman are 2. A woman will release up to ova, on average, during her lifetime. Histologically the ovary is divided into the outer cortex and the inner medulla. The cortex consists of a cellular connective tissue stroma in which the ovarian follicles are embedded. The medulla is composed of loose connective tissue which contains blood vessels and nerves. The cortex is surrounded by a single layer of cuboidal epithelium called the germinal epithelium.

Low magnification view of the pre-ovulation human ovary. The germinal epithelium of the ovary rests upon the ovarian stroma. The primordial germ cells embedded in the stroma are in the cortex of the ovary. In the nullipara, the ovary typically lies in the ovarian fossa, a depression in the pelvic wall below the external iliac vessels and in front of the ureter. A mesovarium attaches the ovary to the posterior wall of the broad ligament, while the posterior margin is free. The peritoneum does not cover the ovary proper, which is covered by germinal epithelium.

At either end the ovary is supported by ligaments. At the tubal pole the ovary is attached to the suspensory ligament, a fold of peritoneum which forms a mesentery for the ovary and contains the ovarian vessels. This suspensory ligament is often called the infundibulopelvic ligament.

At the other pole is the uteroovarian ligament. In men and women, the inner layer of the peritoneum covers the surface of all the organs in the tummy abdomen , such as the stomach, liver and bowel.

The outer layer lines the wall of the abdomen. Between the two layers is a small amount of fluid. This lets the layers move easily against each other. The peritoneum helps protect the organs in the abdomen and keep them in place. A section of the inner layer forms an extra flap of tissue that hangs down from the stomach, in front of the bowel.

This flap is called the omentum. Below is a sample of the sources used in our ovarian cancer information.
