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.
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.
The tunica albuginea is a dense, [1] [2] blue-white [3] layer of fibrous tissue surrounding the testis. [ 1 ] [ 4 ] It is the middle of three envelopes forming the capsule of the testis; it is deep to the visceral layer of tunica vaginalis , and superficial to the tunica vasculosa testis (vascular layer of testis) .
The ovarian surface epithelium, also called the germinal epithelium of Waldeyer, [1] or coelomic epithelium, is a layer of simple squamous-to-cuboidal epithelial cells covering the ovary. [ 2 ] The term germinal epithelium is a misnomer as it does not give rise to primary follicles.
The septa testis are fibrous partitions of the testis dividing the testis into compartments - the lobules of the testis.The septa are formed by extensions of the tunica albuginea - the dense fibrous connective tissue surface covering of the testis - into the substance of the testis.
The theca externa is the outer layer of the theca folliculi.It is derived from connective tissue, the cells resembling fibroblasts, and contains abundant collagen. [1] ...
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.
