FALLOPIAN TUBE

There are two fallopian tubes in the uterus each fallopian tube connect to lateral sides of the uterus.fallopian tube also called uterine tubes or the oviducts.

Each fallopian tube 10 cm long.

EACH FALLOPIAN TUBES DIVIDED IN FOUR PARTS.

1-Interstitial parts.

2-isthmus

3-Ampulla

4-Infundibulum

THE INTERSTITIAL OR INTRAMURAL

It is narrowest part of the fallopian tube and in 1.25 cm in length and situated top of the uterus where fallopian tube extend from the lateral sides of the uterus.

THE ISTHMUS

This is short and narrow and it\’s wall is thick and about 2.5 cm long situated between ampulla and interstitial part.

THE AMPULLA

This is situated between the isthmus and infundibulum it is widest and longest part of uterine tube.fertilization of ocyte by sperm occurs here.

THE INFUNDIBULUM

This is funnel shaped situated distal end of the fallopian tube and it is 1.25 cm long.the opening of the infundibulum into peritoneal cavity is called abdominal ostium.and at the time of ovulation the fimbriae trap the ocyte and sweep it through the abdominal ostium into the ampulla where the ocyte will meet the sperm and fertilization of ovum and sperm take place.

THE FIMBRIAE

It is finger like projection spread over the ovary and it capture the ovum at the time of ovulation and sweep it to the ampula through the abdominal ostium.there are 20 to 30 fimbriae present in fallopian tube .

FUNCTION OF FALLOPIAN TUBE

1-Fertilization takes place at ampula part of fallopian tube.

2-Pyruvate contain in secretion of fallopian tube which nourish the ovum.

3-Transportation of ovum from ovary to uterine cavity through the effect of peristalsis movement and mucosal ciliary function.
