What is the condition where small fragments of the lining of the uterus are found outside the womb

Endometriosis which is a long-term condition where small fragments of the lining of the uterus are found outside the womb, mainly on the ovaries and fallopian tubes. This leads to painful shedding of these pieces which cause blockage of the fallopian tubes and extreme pain.

What is the innermost layer of the fallopian tube?

The mucosa which is the innermost layer of the fallopian tubes lines the hollow lumen and is made of ciliated columnar epithelial tissue. The arterial supply of the fallopian tubes is from the branches of ovarian and uterine arteries, and the nerve supply is via both sympathetic and parasympathetic nerves.

What is the role of the fallopian tubes in the ovum?

The fallopian tubes are involved in the transport of the ovum from the ovary to the uterus. This is aided by the peristaltic contractions of the muscular layers of the tubes and by the wave-like movement of the ciliated cells.

What are the structures that connect the peritoneal cavity to the uterine cavity?

Fallopian tubes. The fallopian tubes are important structures in the female reproductive tract, which connect the peritoneal cavity with the uterine cavity. They provide a site for fertilisation and are involved in the transport of the ovum from the ovaries to the body of the uterus.

Which part of the menstrual cycle is the ciliated cell most predominant?

The ciliated cells are more predominant in the distal portion of the tubes and develop more cilia in the first half of the menstrual cycle. The wave like movement of the cilia aids in the movement of the ovum throughout the fallopian tubes.

What is tubal pregnancy?

It is also known as tubal pregnancy. Any damage in the fallopian tube lining may hinder the further movement of fertilised egg and it gets lodged there. It can lead to internal bleeding and rupture.

Structure and Function of Fallopian Tube

The uterine, isthmus, ampulla, and infundibulum are the four anatomical regions of the fallopian tube. The uterine ostium and a brief portion closest to the uterine horn are located most medially in the uterine region. The uterine portion is next to the isthmus.

Blood Supply and Lymphatics

Anastomoses between the ovarian and tubal branches of the ovarian artery and ascending branches of the uterine artery provide vascular feed to the fallopian tube. The ovarian arteries branch off the abdominal aorta on each side, inferior to the renal arteries' origin.

Embryology of Fallopian Tube

The paramesonephric or Müllerian ducts give rise to the fallopian tubes. The mesoderm, the middle layer of one of the embryo's three basic germ layers, gives rise to these ducts. The ectoderm and endoderm are the other two layers.

Clinical Significance of Fallopian Tube

Several gynecologic illnesses involve the fallopian tubes, necessitating the operations indicated before. Ectopic pregnancies most commonly occur in the ampulla, which can be treated medically or surgically with a salpingostomy (tube opening) or salpingectomy (tube removal) (tube excision and removal).

Surgical Considerations of Fallopian Tube

Salpingo-oophorectomy: elimination of the ovaries and fallopian tube, Salpingectomy: excision of the fallopian tube, Salpingostomy: surgical cut into the fallopian tube to provide an aperture, Tubal ligation: female surgical sterilization by occlusion, withdrawal, or ligation of fallopian tubes.

Things to Remember

The mucous membrane contains cells with fine hair-like structures projections called cilia that help propel the egg and sperm through the fallopian tubes, in addition to cells that release fluids.

What is the term for the monthly cycle of changes in the ovaries and the lining of the uterus

Menstrual Cycle. The monthly cycle of changes in the ovaries and the lining of uterus or endometrium is termed as the menstrual cycle . This menstrual cycle ceases when the egg is fertilized, and pregnancy begins. The menstrual cycle occurs in two phases: the follicular phase of the menstrual cycle and the Ovulatory phase of menstrual cycle .

What is the central part of the uterine tube that guides the egg?

The extremities of the fimbriae spread over the ovary contracting close to the surface of the ovary during the ovulation to guide the freely moving egg suitably. Following the infundibulum is the central, long part of these uterine tubes known as the ampulla.

What is the role of fallopian tubes in ovulation?

In case of fertilization as a result of the presence of sperms, the fallopian tubes conduct the transportation of the fertilized egg to the uterus for its firm implantation. ...

What are the phases of the menstrual cycle?

The monthly cycle of changes in the ovaries and the lining of uterus or endometrium is termed as the menstrual cycle. This menstrual cycle ceases when the egg is fertilized, and pregnancy begins. The menstrual cycle occurs in two phases: the follicular phase of the menstrual cycle and the Ovulatory phase of menstrual cycle. The follicular phase is the first day of the period. The following events occur during this follicular phase: 1 Hormones like Follicle stimulating Hormone (FSH) and Luteinizing Hormone (LH), are released from the brain and travel in the blood to the ovaries. 2 The hormones stimulate the growth of about 15 to 20 eggs in the ovaries which have a separate shell known as a follicle. 3 The FSH and LH also trigger a rise in the production of the female hormone called estrogen.

What is the function of glucose in the mucous membrane?

While the other constituents mentioned render a suitable environment for fertilization, glucose serves as a nutrient for the sperms and eggs. The mucous membrane possesses cells containing cilia – fine hair-like projections. They help in the movement of the sex cells.

What are the hairlike projections on the lining of the fallopian tube?

The fallopian tubes show fine hair-like projections known as cilia on cells of the lining. These cilia of the tube are necessary for egg-movement from the tube to the uterus. If these cilia are caused any harm as a result of any infection, it may hinder the movement of the egg forward and may continue to stay in this tube itself.

How long does it take for sperm to arrive in the uterus?

In any case, the eggs arrive in the uterine cavity in about 3-4 days.

How many fallopian tubes are there in a female?

Females have two fallopian tubes in their reproduction system that are ~10cm long and extend from the uterus towards the right and left ovaries. Specifically, they extend off of the uterine horns of the uterus. However, the fallopian tubes do not make direct contact with the ovaries. Instead, they end near the ipsilateral ovaries, where a specific fimbria- known as the fimbria ovarica – forms a connection from the end of the fallopian tube to the ovary. The cells of the fimbriae contain cilia (which are small hair-like projections that stem off the cells), which create a current towards the fallopian tubes.

What is the fallopian tube?

The fallopian tube (s) – also known as “uterine tubes” or “oviducts”- are two hollow ducts in the female reproduction system where oocyte fertilization occurs. There are two tubes present in the system, where each extends from the uterus in the right and left directions and ends near the right and left corresponding ovaries.

What are the four sections of the fallopian tube?

The fallopian tubes themselves consist of four sections, including the uterine, isthmus, ampulla, and infundibulum regions. The uterine region is closest to the uterine horns, with the isthmus region being the next section away from the uterus. The ampulla is the third region from the uterus and is commonly the location of oocyte fertilization.

What is the role of the fallopian tube in the ovarian cycle?

The Fallopian Tube’s Role in the Ovarian Cycle. It has been assumed that females have all of their oocytes upon birth. (However, some research may challenge this assumption, as data shows that it may be possible for epithelial cells to create stem cells at the ovary’s surface.

What is the purpose of fallopian tubes?

The fallopian tubes are a common site for disorders- such as ectopic pregnancies- and infections- such as with sexually transmitted diseases. They also offer a convenient location to perform voluntary sterilization in women who do not wish to have children. Fallopian tube.

Where does the secondary oocyte enter the fallopian tube?

The secondary oocyte surrounded by mature follicle cells is released from the ovaries and enters the fallopian tubes during ovulation. The secondary oocyte then waits at metaphase II of meiosis while the mature follicle cells rupture to form a structure known as the corpus luteum.

Where do oocytes go when they are fertilized?

Instead, the oocytes remain in the fallopian tubes, where they become fertilized if sperm (the male gametes) is present. If fertilization does occur, peristalsis of the fallopian tubes then moves the fertilized oocyte (now called a zygote) into the uterus, where the zygote is able to implant itself to the uterine lining.
