ovarian cortex
The layer of the ovary lying immediately beneath the tunica albuginea, composed of connective tissue cells and fibers, among which are scattered primary and secondary (antral) follicles in various stages of development; the cortex varies in thickness according to the age of the individual, becoming thinner with advancing years; included in the follicles are the cumulus oophorus, membrana granulosa (and the granulosa cells inside it), corona radiata, zona pellucida, and primary oocyte; the zona pellucida, theca of follicle, antrum and liquor folliculi are also contained in the follicle; also in the cortex is the corpus luteum derived from the follicles. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the ovarian cortex is
The layer of the ovary lying immediately beneath the tunica albuginea, composed of connective tissue cells and fibers, among which are scattered primary and secondary (antral) follicles in various stages of development; the cortex varies in thickness according to the age of the individual, becoming thinner with advancing years; included in the follicles are the cumulus oophorus, membrana granulosa (and the granulosa cells inside it), corona radiata, zona pellucida, and primary oocyte; the zona pellucida, theca of follicle, antrum and liquor folliculi are also contained in the follicle; also in the cortex is the corpus luteum derived from the follicles. The atlas records it as a organ at the organ scale in the human body.
Where the ovarian cortex is
It sits within the reproductive system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.
What the ovarian cortex connects to
The atlas records 4 typed relationships for it, across 2 kinds of connection. part of ovary and reproductive system.
Supply and innervation
This dataset asserts no arterial supply, venous drainage or innervation for the ovarian cortex. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.
Also called
Also recorded as cortex of ovary and cortex ovarii (zona parenchymatosa). Searching any of those names reaches this page.

Questions
Where is the ovarian cortex?
It sits within the reproductive system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.
What does the ovarian cortex connect to?
Part of: ovary and reproductive system.
Is the ovarian cortex the same in other species?
Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
