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 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. The stroma of the ovary may contain interstitial cells resembling those of the testis.
Tunica albuginea is a general term for a tunic of whitish connective tissue. In human anatomy, it generally is applied in three contexts: the fibrous sheath of the corpora cavernosa penis, the fibrous tunic of the testis, and the connective tissue tunic around the ovaries. [6] Tunica dartos is a muscular tunic beneath the skin of the scrotum ...
These cells are derived from the mesoderm during embryonic development and are closely related to the mesothelium of the peritoneum.The germinal epithelium gives the ovary a dull gray color as compared with the shining smoothness of the peritoneum; and the transition between the mesothelium of the peritoneum and the cuboidal cells which cover the ovary is usually marked by a line around the ...
The ovaries are surrounded by a capsule, and have an outer cortex and an inner medulla. [4] The capsule is of dense connective tissue and is known as the tunica albuginea. [5] Usually, ovulation occurs in one of the two ovaries releasing an egg each menstrual cycle.
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
Like the ovary, in its earliest stages it consists of a central mass covered by a surface epithelium. In the central mass a series of cords appear, and the periphery of the mass is converted into the tunica albuginea , thus excluding the surface epithelium from any part in the formation of the tissue of the testis.
A depiction of the ovarian cycle in animals. In human adult females, the primordial follicle is composed of a single oocyte surrounded by a layer of closely associated granulosa cells. In early stages of the ovarian cycle, the developing follicle acquires a layer of connective tissue and associated blood vessels. This covering is called the theca.
