Uterine Tube

Other name: fallopian tube

Fallopian tube is a tortuous 10cm duct. One end is freely open to the peritoneal cavity and the other end is attached to the uterus. It receives ovum (egg) from the ovary and convey ovum to the uterus. The tube also provides a site, ampulla, where fertilization of the ovum can take place. It serves as channel along which the spermatozoa travel to reach the ovum for fertilization. If egg is fertilized the tube provides nourishment and propogates fertilized product to the uterus for implantation. The unfertilized ovum shed out during menstrual bleeding from the uterus.

Location and Description
Fallopian tube is a muscular tubes, located in the upper border of the broad ligament connecting the uterine cavity with the peritoneal cavity in the region of the ovary

Fallopian tube is subdivided into 4 parts (from lateral to medial):

Infundibulum
A funnel-shaped lateral end that projects beyond the broad ligament and overlies the ovary
The free edge is broken up into a number of fingers like processes, the fimbriae, which are draped over the ovary

Ampulla
It is thin walled, dilated, tortuous and widest part of the tube. The ampulla is around 4 mm in diameter. It is the usual site of fertilization and it is also most common site of tubal ectopic pregnancy

Isthmus
It is the narrowest part of the tube and lies just lateral to the uterus

Uterine Part
This part of the tube pierces the uterine wall and is about 1 cm in length. It opens to the utrine cavity by a narrow uterine ostium. The uterine ostium is around 1 mm in diameter.

Blood Supply

Arteries
The uterine arteries supplies medial two third and ovarian supplies lateral one third of the tube

Veins correspond to the arteries

Lymphatic Drainage:
The lymphatic vessels join the lymphatic from ovaries and uterus and finally drains to the internal iliac and paraaortic nodes

Nerve Supply: inferior hypogastric plexuses
