PP2.H2.3 +D1 Ovary

Ovary:

  • Each ovary has a medulla and a cortex, and is covered over by a layer of epithelial cells called the germinal epithelium
  • The medulla is characterised by the presence of numerous blood vessels which branch and are distributed through the cortex
  • The cortex consist of a connective tissue stroma within which are located the ovarian follicles
  • The germinal epithelium is a simple cuboidal epithelium
  • At the mesovarium, where the ovary is attached to the broad ligament, the germinal epithelium is continuous with the peritoneum
  • The germinal epithelium is so called because it was once thought to be the source of the ova
  • This is now known not to be the case but the name has stuck
  • When a mature ovarian follicle ruptures to releases its ovum, the germinal epithelium is breached so that the ovum (theoretically) is deposited into the peritoneal cavity
