Ovaries

(2)

Paired

Produce ova in follicles

Located lateral to the superior portion of the uterus.

Primary follicle

(2)

Begin forming in puberty

Graafian follicle

(4)

one produced every 28 days until menopause (age 40-45)

(13/year, approx. 400 in a lifetime)

200x bigger than sperm cell

at birth: 2 million oogonia (potential egg cell)

at puberty: 400,000

Ovum

(8)

If not fertilized in 48 hours after ovulation, the egg will begin to decompose.

Corpus luteum

(6)

Develops from an ovarian follicle during the luteal phase of the menstrual cycle, following the release of a secondary oocyte from the follicle during ovulation.

Remains in the ovary while the oocyte follows the uterine tube to the uterus.

Uterine tube

(11)

Extend to ovaries

Lined with cilia. Cilia beat constantly to move egg or fluid towards uterus. keeps pathogens from traveling into body cavity

walls made of smooth muscle, egg moves through peristalsis

Infundibulum

(6)

"funnel-shaped"

Fimbria

(5)

partially encases ovary but not attached

"finger-like"

Ampulla

(7)

Intermediate portion of the uterine tube.

Cervix

(27)

The narrowed region that leads to the vagina

Endometrium

(15)

inner lining of uterus.

Highly vascular

This section enlarges (thickens) to prepare the uterus for the implantation of a fertilized.

The fertilized egg will implant here (7 days after ovulation)

Forms part of placenta

Myometrium

(13)

Middle (thickest) layer of uterus

made of smooth muscle - longitudinal, circular, oblique

Responsible for uterine contractions

Can contract with 100 lb of force

Stimulated by oxytocin

perimetrium

(14)

Outside lining of the uterus.

Part of parietal peritoneum (lining of abdominal cavity)

retroperitoneal (outside of body cavity)

Labia minora

(12)

Labia majora

(11)

Corpus luteum

(6)

The corpus luteum, which means yellow body in Latin, is what is left of the follicle after a woman ovulates. During the follicular phase of a woman's cycle, several follicles develop under the influence of FSH (follicle stimulating hormone). Each follicle contains an egg. In a typical cycle only one egg will become mature enough for ovulation. When a woman ovulates the egg will burst from the follicle. Then what is left of the follicle will become the corpus luteum. The luteal phase, named after the corpus luteum, is the second half of a woman's menstrual cycle. The luteal phase begins after ovulation and continues until menstruation occurs.
