FEMALE REPRODUCTIVE SYSTEM

PERINIUM

- Diamond shape

- Contains genitalia and anus

MONS PUBIS

- mound of fats beneath and symphysis pubis

• puberty..... PUBIC HAIR

LABIA MAJORA

skin fold with hair

• pudendal cleft

• space in between labia majora

• sweat, sebaceous glands, apocrine

• homologue of male scrotum

LABIA MINORA

- Skin fold, hairless

• Few sweat gland

• Many sebaceous gland

VESTIBULE

- space between labia minora

paraurethral glands (skene’s gland)

- secretes mucus

• homologue to prostate

• vaginal orifice

• guarded with hymen

VAGINA

- fibromuscular canal

• lined by mucous membrane

• hymen - partial covering of canal

• fornices

Vagina

- receives the penis during sexual intercourse

• Birth canal

• Outlet of menstrual flow

Rugae

Vagina is COMPOSED of

Acidic

The PH of Vagina is

PERIMETRIUM

- OUTER COVERING

• derived from peritoneum

• forms the uterovesical and rectouterine pouch

MYOMETRIUM

- MIDDLE LAYER

• Smooth muscles

• Thickest at the fundus and thinnest at the cervix

• Response to oxytocin stimulation during labor and delivery

ENDOMETRIUM

- INNERMOST

• Contains endometrial glands

• Response to estrogen and progesterone that prepares the uterus for possible implantation

STRATUM FUNCTIONALIS

- slough off during menstruation

STRATUM BASALIS

- does not slough off during menstruation

STRATUM BASALIS

gives rise to a new STRATUM FUNCTIONALIS

Ampulla

- site of fertilization

• longest, lat 2/3

• most dilated

Isthmus

- narrowest

Fallopian tube

Provide route for sperm to reach the ovum

• Transport oocyte from ovary to fallopian tube during ovulation

• Site of oocyte digestion if no fertilization

• Transport fertilized ovum to be implanted in the endometrium of the uterus

OVARY

- produces oocyte

• Almond shape

• located lateral to the uterus

PROGESTERONE AND ESTROGEN

- prepares the uterine glands and maintains the endometrium for implantation

• Prepares the mammary for milk production

• inhibits FSH and LH if high

INHIBIN

- secreted by granulosa cell

• inhibits FSH secretion

RELAXIN

- relaxes the uterus during implantation and pregnancy

• helps dilate the cervix from the ovary & placenta

GnRH

Controlled by WHAT from hypothalamus that causes the release of FSH and LH

ESTROGEN

- maintenance of female repro, secondary characteristics

• BREAST DEVELOPMENT

PROGESTERONE

- secreted by corpus luteum

• acts synergistically with estrogen

OVARIAN CYCLE

WHAT CYCLE involves maturation of oocyte B.

UTERINE CYCLE

WHAT CYCLE changes in the endometrium

OVULATION

- Release of the secondary oocyte into the fallopian tube

• during 14th day of a 28th day cycle

3-5 days

MENSTRUAL PHASE - last for

MENSTRUAL PHASE

decreased estrogen and progesterone level in the blood causes ischemia of functionalis leading to menstruation

MENARCHE

- Onset / start of menstration

MENOPAUSE

- Sesation / Stop menstration

AMENORRHEA

- absence of menstrual cycle -

• bec of mulfuction of PG or tumor in pituitary galnd

ECTOPIC PREGNANCY

- pregnancy out side in uretus

PLACENTA PREVIA

- implantation of placent in the entrance, malapit sa cervex
