ANATOMY OF FALLOPIAN TUBE & OVARY Dr. Sharon D. Rasquinha Assistant Professor

FALLOPIAN TUBE : Also known as oviducts Transport the ova from ovary to uterus each month. In case of fertilization, tubes transport the fertilized egg to uterus for implantation.

Anatomy : Uterine appendages located bilaterally at superior portion of uterine cavity. They are present at the cornua. 10cm in length 1cm in diameter and situated within mesosalpinix

Parts : Isthmus Ampulla Infundibulum Fimbriae

Blood supply : Nerve supply : Lymphatic drainage : Branches of uterine and ovarian arteries Nerve supply : Both sympathetic and para sympathetic Lymphatic drainage : Iliac and lateral aortic nodes

Microscopic : 3 layers – Mucosa Muscularis Serosa Cell type within mucosa - columnar ciliated epithelial cells (25%) Secretory cells (60%) Peg cells (10%)

Ovary Egg or nut Analogous to tests in male Gonads and endocrine glands

Structure : Whitish in colour Located along lateral wall of uterus in a region ovarian fossa Fossa is beneath external iliac artery and in front of ureter and internal iliac artery 4cm x 3cm x 2cm in size

Ligaments : Paired ovaries are within pelvic cavity. Attached to uterus via cord – ovarian ligament

Extremities : The end to which fallopian tube attaches – tubal extremity and ovaries connected to it infundibulopelvic ligament. The other extrimity – uterine extrimity attached to uterus – ovarian ligament

Histology : Germinal epithelium Ovarian cortex : Follicles and there is stroma in between them Follicles : Cumulus oophorus Membrana granulosa Corona radiata Zona pellucida Primary oocyte Inner most layer – ovarian medulla

Functions : Egg cells (oocyte) Endocrine – Estrogen, testorterone and progesterone
