The oviduct is a pair of tall and slender fistula, span 7.4-13.2cm, the diameter (outer diameter) approximately 0.5cm. The oviduct located at the fundus of uterus both sides, in the womb extravagant ligament’s upper limb, its inner end and the fundus of uterus flank angle is connected, outside the end arrives at ovary’s place above, in the ion abdominal cavity. Each side oviduct has two apertures, an aperture in uterine cavity, another aperture in peritoneal cavity. The oviduct often because of the vagina, womb’s upward infection or the peritoneal cavity inflammation exhausts oneself.
??(1) oviduct’s shape: The oviduct by the fundus of uterus and the uterus border’s department both sides outset, the water stretches out straight in front of oneself first outward, arrives at nearby the ovary lower extremity to change upward, in ovary upper extreme, then curving backward, along ovary after skirt downward, surrounds ovary’s upper extreme. The oviduct from inside to outside may divide into four, namely womb department (womb intermural), canyon, ampule and funnel.
???Oviduct’s womb department (Uterine part) or womb intermural (Utehne interstitialpart): The oviduct womb department is passes through a womb wall’s section from the womb flank angular orientation, long approximately lcm, its inner end opens the mouth by the thin funnel shape in the uterine cavity, is called oviduct uterine orifice (Uterineorificeofuterinetube), the diameter approximately 0.1cm, compares the abdomen tone to be small.
???Oviduct canyon (1sthmusofuterinetube): The oviduct canyon is extends outward from the womb flank angle level, reaches nearby the ovary lower extremity a section, approximately composes the oviduct span 1/3, inscribes the oviduct womb department, outside loses one game after another the oviduct ampule. This short and thin straight, wall thickness cavity is narrow. The salpingitis easy to cause the canyon department jamming to cause sterile or the extra-uterine pregnancy. In the clinical birth control surgery, the oviduct canyon department is the tubal ligation and the silica gel agglutination technique first choice spot.
???Ampulla tubae uterinal (Ampullaofuterine tube): The ampulla tubae uterinal extension carries in oviduct canyon’s outside, is the oviduct is longest, a caliber thickest section. Its length is 3.47-4.13cm, approximately composes the oviduct span 2/3, the diameter (outer diameter) is 0.37-0.47cm. The oviduct pot abdomen assumes “S” curving, from the ovary lower extremity results from outside the oviduct canyon department to carry, first to layman, then curved upward, along ovary predestined affinity upward, to ovary upper extreme, then curving backward, divides and hyphenates a word at the end in the funnel department. The pot abdomen is the egg fertilization place, if the fertilized egg implants this, then forms the tubal pregnancy.
???Oviduct funnel (1nfundibulumofuterine tube): The oviduct funnel oviduct’s terminal, expands first assumes the funnel shape. Funnel’s central committee, has oviduct abdomen tone (Abdominalorificeo{uterinetube). When funnel’s department myo- level relaxation, this diameter is 0.24-0.36cm. Funnel’s boundary has most radiated anomalous prominences, is called the oviduct umbrella (Fimbriaeofuterine tube), long 0.42-0.55cm. The oviduct umbrella’s inside lid has the mucous membrane, longest breaks out, is called ovarian fimbria (Ovarianfimbria), is connected with the ovary surface. In the ovarian fimbria on the mucous membrane ditch must be deeper than the oviduct umbrella on, therefore, some people thought that the ovarian fimbria possibly is guides the egg to enter the oviduct abdomen tone the circuit.??(2) oviduct’s blood vessel, lymph vessel and nerve:
???Artery: Mainly and oviduct canyon distributes by arteria uterina’s oviduct; The oviduct funnel department has arteria ovarica’s umbrella distribution, the two tallies mutually, and sends out 20-30 small to distribute in the pipe wall, and tallies mutually the net.
???Vein: A part enters the womb vagina clump, another part enters the ovary vein clump.
???Lymph vessel: With enters the waist lymph node with on the ovary and womb’s lymph vessel.
???Nerve: Mainly by comes from the plexus ovaricus and the womb vagina clump of nerve and the sympathetic nerve control.
