OVARIES

OVARIES 















1.INTRODUCTION: - ovaries are the female gonads  (glands producing sex harmones and the ova)

2.SITUATION: -       These lies on shallow  fossa on the lateral wall of the pelvis.

3.MEASURMENTS:-

                        Length- 2.5 to 3.5 c.m long

                        Wide – 2 cm

                        Thick – 1 cm

b. Ligament: ovarian ligament – upper rest

                        Broad ligament –Lower

4.STRUCTURE:-Ovaries is made up of 2 layers of tissue .

THE MEDULLA:-

 This lies in the centre and consists  of fibrous tissue blood vessels  & nerves.

THE CORTEX:-

Ø  It surrounds the medulla.

Ø  It has a Frame work of connective tissue, or stroma, covered by germinal epithelium.

Ø   For 1 graffian  follicle it later 28 days for matures, ruptures &  releases its ovum into the peritoneal cavity. This is called ovulation &  it occurs during most menstrual cycle.

5. BLOOD SUPPPLY:

ARTERIAL SUPPLY: ovarian arteries-which are  branch from the abdominal aorta

VENOUSDRINAGE:           

                          inferior venecava &  lt renal vein.

6.NERVE SUPPLY:- 

The ovaries are supplied by para-sympathetic nerves from the sacral outflow

sympathetic nerves from the lumbar outflow.

7.LYMPH DRAINAGE
    This is to the lateral aortic and preaortic lymph nodes.

FUNCTIONS:

1.      Maturation Stimulation of FSH

2.      Production of Luteinising Hormone.

3.      Develop of Corpus luteum  (Yellowbody)

4.      Corpus luteum produce the progesterone & Ocrthrocin.

5.      Production of  Human choroimic gonadotrophin (HCG)
