Structure of the Perineum• Skin covered

muscular region between the vagina and the anus.

• Diamond-shaped between the thighs

Function of the Perineum• Prevents involuntary seepage from the

rectum (keeps feces inside colon)

• Can be torn during childbirth.

Episiotomy = Cutting of Perineum

Structure of Uterus• Pear-shaped organ 3” long, 2” wide, 1”

thick that acts as a womb

• Located between bladder and rectum

• Ligaments hold it in place

• Made up of 3 layers– Endometrium – mucous membrane that has

large blood supply; where zygote attaches– Myometrium – thick layer of muscle to

support uterus and propel baby out– Periotoneum – layer furthest from baby

Function of the Uterus• Permits sperm to move toward the

fallopian tubes for fertilization

• Provides nutrients to embryo until placenta is formed

• Contracts to push baby out during labor

Uterus

Prolapsed Uterus• Ligaments and muscles holding the uterus

in place get weak

• Uterus moves and exits the vagina
