–Centered in pelvic cavity, behind bladder
& in front of rectum
Leans forward of uterus called
anteversion
Two major parts of uterus
corpus and cervix
– Mature size of uterus
6–8 cm long
the Isthmus of uterus is
Lower uterine segment
isthmus location
Portion of uterus between internal
cervical os, endometrial cavity
Nidation is
Preparation of uterine lining by steroid
hormones for implantation of embryo
Uterine corpus

layers of Uterine corpus is
(perimetrium)
(myometrium)
(endometrium)
ciliated epithelium, change thickness during cycle
endometrium

menopause in absence of pregnancy
endometrium
Cervix
is the lower part of the uterus that connects to the vagina.
Internal Os
is the opening of the cervix towards the uterus.
External Os
is the opening of the cervix towards the vagina.
Broad Ligament
Folds of peritoneum, draped over fallopian tubes like a curtain.
Round Ligament
Maintains anteverted position of the uterus.
Ovarian Ligament
Supports ovaries.
Cardinal Ligament
Supports cervix (cx) to lateral wall.
Infundibulopelvic Ligament
Supports ovaries.
Uterosacral Ligament
Supports cervix (cx) to sacrum.
Fallopian Tubes form of
2 tubes, each has 3 parts.
Isthmus of fallop tubes
Narrow part, 2.5 cm from uterus.
Ampulla
Dilated portion, 5 cm.
Fimbria
Funnel-shaped end, has fimbriae (finger-like) at the end.
Functions of Fallopian Tubes
✅ Transport ovum to uterus.
✅ Site for fertilization.
✅ Nourishing environment for ovum/zygote.
Ovaries is
Female sex glands.

ovaries dimensions
3 cm long, 1.5 cm wide, 1 cm thick.
