Under normal circumstances, the suspensory part keeps the uterus in anteflexion and anteversion (in 90% of women) and keeps it "floating" in the pelvis. The meanings of these terms are described below:

The sustentacular part supports the pelvic organs and comprises the larger pelvic diaphragm in the back and the smaller urogenital diaphragm in the front. The pathological changes of the position of the uterus are:

retroversion/retroflexion, if it is fixed
hyperanteflexion – tipped too forward; most commonly congenital, but may be caused by tumors
anteposition, retroposition, lateroposition – the whole uterus is moved; caused by parametritis or tumors
elevation, descensus, prolapse
rotation (the whole uterus rotates around its longitudinal axis), torsion (only the body of the uterus rotates around)
inversionIn cases where the uterus is "tipped", also known as retroverted uterus, the woman may have symptoms of pain during sexual intercourse, pelvic pain during menstruation, minor incontinence, urinary tract infections, fertility difficulties, and difficulty using tampons. A pelvic examination by a doctor can determine if a uterus is tipped. Blood supply
The human uterus is supplied by arterial blood both from the uterine artery and the ovarian artery. Another anastomotic branch may also supply the uterus from anastomosis of these two arteries. Nerve supply
Afferent nerves supplying the uterus are T11 and T12. Sympathetic supply is from the hypogastric plexus and the ovarian plexus. Parasympathetic supply is from the S2, S3 and S4 nerves. Development
Bilateral Müllerian ducts form during early human fetal life. In males, anti-müllerian hormone (AMH) secreted from the testes leads to the ducts regression.
A congenital lip pit or lip sinus is a congenital disorder characterized by the presence of pits and possibly associated fistulas in the lips. They are often hereditary, and may occur alone or in association with cleft lip and palate, termed Van der Woude syndrome. Diagnosis
Classification
They are divided into three types based on their location:
commissural pits, which are small pits near the labial commissure of the mouth,
a pit in the upper lip, in which case it may be called a midline sinus of the upper lip, and
pits in the lower lip, in which case it may be called a congenital sinus of the lower lip.In some cases commissural pits have been reported in combination with preauricaluar pits, which are near the ear. Treatment
Lip pits do not usually require any treatment, although in some reported cases surgical excision has been used or if associated with a draining sinus tract. See also
