Many of the features found in ovaries are common to all vertebrates, including the presence of follicular cells and tunica albuginea There may be hundreds or even millions of fertile eggs present in the ovary of a fish at any given time. Fresh eggs may be developing from the germinal epithelium throughout life. Corpora lutea are found only in ...
Again, corms of iridaceous species, such as some Watsonia and the larger species of Gladiolus, accumulate thick, reticulated, fibrous or woody defences. More generally than in describing tunics of bulbs etc., any leaf-sheath or protective bract remaining attached to the plant after the leaf has died may be called a tunica or tunic. [3]
Tunica albuginea may refer to: Tunica albuginae (clitoris), the fibrous-elastic sheath of connective tissue that surrounds the shaft and glans of the clitoris; Tunica albuginea oculi, the tough fibrous layer that covers most of the eyeball; Tunica albuginea (ovaries), the connective tissue covering of the ovaries
Stromal cells associated with maturing follicles may acquire endocrine function and secrete estrogens. The entire ovarian stroma is highly vascular. [1] On the surface of the organ this tissue is much condensed, and forms a layer (tunica albuginea) composed of short connective-tissue fibers, with fusiform cells between them.
Many of the features found in human ovaries are common to all vertebrates, including the presence of follicular cells, tunica albuginea, and so on. However, many species produce a far greater number of eggs during their lifetime than do humans, so that, in fish and amphibians, there may be hundreds, or even millions of fertile eggs present in ...
The tunica albuginea is composed of short connective tissue fibers. It is located immediately inside the surface epithelium (previously known as germinal epithelium) which is continuous with the peritoneum. It is non-vascularised. [1] It is thinner than the tunica albuginea of the testis, and its thickness varies across the ovary. [1]

The egg cell or ovum (pl.: ova) is the female reproductive cell, or gamete, [1] in most anisogamous organisms (organisms that reproduce sexually with a larger, female gamete and a smaller, male one). The term is used when the female gamete is not capable of movement (non- motile ).
