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).
Under a tough membranous shell, the tunica albuginea, the testis of some teleost fish, ... The eggs have an average diameter of 1 millimetre (0.039 in).
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 ...
Just before birth, the upper part of the vaginal process, at the internal inguinal ring, usually becomes closed, and this obliteration extends gradually downward to within a short distance of the testicle. The process of peritoneum surrounding the testis is now entirely cut off from the general peritoneal cavity and constitutes the tunica ...
The tunica albuginea is the fibrous envelope that extends the length of the corpus cavernosum penis and corpus spongiosum penis. It is a bi-layered structure that includes an outer longitudinal layer and an inner circular layer. [1]
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
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.
An ovarian follicle is a roughly spheroid cellular aggregation set found in the ovaries.It secretes hormones that influence stages of the menstrual cycle.At the time of puberty, women have approximately 200,000 to 300,000 follicles, [1] [2] each with the potential to release an egg cell (ovum) at ovulation for fertilization.
