The fallopian tubes are the place where happens the fertilization of the ovum or female gamete , by a sperm , or male gamete . These are two channels of equal shape, which connect the two ovaries to the uterus. Salpingi are also called uterine tubes, fallopian tubes, fallopian tubes, or oviducts . The ovaries are the organs that produce the oocytes to be fertilized, while the uterus has the task of preparing the possible implantation and maturation of the fertilized egg.
What are salpingi?
The word salpinge derives from the Greek salpinx which originally designated a “trumpet” or “tuba” . They were first identified by the Italian anatomist Gabriele Falloppio, and have since been known as “fallopian tubes”.
The salpingi are two symmetrical channels that connect each of the two ovaries with the uterus. The salpingi are 12 to 18 centimeters long, and are up to 3 millimeters thick. They give rise to the group known as uterine appendages , together with the ovaries .
The salpingi are anatomically composed as follows:
The infundibulum . This is the first part, characterized by a funnel shape which is the part closest to the ovaries. It ends with a pavilion surrounded by fringes (called fimbrie in medical language) which when the egg is released by the ovarian follicle allow it to pass into the tuba itself.
The ampoule is the longest and most tortuous portion of the salpingi, and has a length of about 7-8 centimeters. On the one hand, it allows the passage of eggs and spermatozoa when it contracts. On the other hand, if fertilization takes place, it allows embryonic transit.
The isthmus , which is thinner and rectilinear, about 3-4 centimeters long.
The part of the salpingi located in the uterus (called interstitial or intramural), is the final part and constitutes the tract in which the tubes enter the uterine cavity.
What are salpinges for?
The salpingi have a dual function : they allow the migration from the ovaries to the uterus of the mature egg released by the ovarian follicle ready for fertilization; they intercept the egg (female gamete) and the spermatozoon (male gamete) and allow it to meet, giving rise to fertilization
