Uterus is supported and prevented from sagging down by many factors which are chiefly muscular and fibromuscular.
MUSCULAR OR ACTIVE SUPPORTS
- Pelvic diaphragm.
- Perineal body.
- Distal urethral sphincter mechanism.
FIBROMUSCULAR OR MECHANICAL SUPPORTS
- Uterine axis.
- Pubocervical ligaments.
- Transverse cervical ligaments of Mackenrodt.
- Uterosacral ligaments.
- Round ligaments of uterus
- Broad ligaments.
- Vesicourethral pouch and fold of peritoneum.
- Rectovaginal or rectouterine pouch and fold of peritoneum.
Now, to memorise it, here is the picnomic. Keeping the following picture in mind would help in recalling most of it.
So, let’s go through the picture.
The girl with the wings in the picture represents uterus, cervix and vagina. The pink top is the uterus, the white belt is the cervix and the pink skirt is the vagina.
Now the trampoline on which the girl is standing, represents the pelvic diaphragm and the brown spot is the perineal body and the motor attached to the trampoline represents the sphincter. This covers the active supports of the uterus. So when you wish to recall the active supports of uterus, just remember the girl standing on the trampoline.
Moving on, the green pockets formed at the angle (90˚) of the skirt and top of the girl can be related to the angle of inversion which will help to memorize the role of uterine axis as the support. The two ropes tying the girl to the wall represents the pubocervical ligament and uterocervical ligament attached to the cervix and uterus respectively. The colored beads on the belt (cervix) represents the transverse ligament.
The wings of the girl can be associated to the broad ligament of the uterus and the holes in the wing represents the round ligament. The blue colored folds of the curtain can be related to the folds of peritoneum.
So, keep the complete picture in mind, or try making a story based on this. One glimpse of the picture, and you can revise all the supports. Hope it helps.
