The superficial cortex is more fibrotic than the deep, and is called the '''tunica albuginea'''. On the surface of the ovary is the '''germinal epithelium'''. This is a continuation of the '''peritoneum'''.

The medulla is highly vascular. It contains hilus cells, which are similar to the Leydig cells of the [[Male Reproductive Tract - Horse Anatomy#Testes|testes]].

===Vasculature===
====Arterial Supply====
* The '''ovarian artery''' (a branch of the Aorta) and ovarian branches of the '''uterine artery''' form anastomoses in the mesovarium and the [[Broad Ligament - Anatomy & Physiology|broad ligament]]. From this arterial plexus ~10 coiled '''helicine arteries''' enter the hilus of the ovary. Smaller branches form a plexus at the '''corticomedullary junction''', giving rise to straight '''cortical arterioles''', which radiate into the cortex. Here they branch and anastomose to form '''vascular arcades''', which give rise to a rich capillary network around follicles.
====Venous Drainage====
Venous drainage follows the course of the arterial system. '''Medullary veins''' are large and tortuous. The '''ovarian artery''' is closely associated with the '''uterine vein'''. This is important for the transfer of luteolytic PGF2α from the [[Female Reproductive Tract - Horse Anatomy#Uterus|uterus]] to the ovary.
