Because its main function is to nourish developing sperm cells through the stages of spermatogenesis, the Sertoli cell has also been called the "mother" or "nurse" cell. [10] Sertoli cells also act as phagocytes, consuming the residual cytoplasm during spermatogenesis. Translocation of cells from the basal lamina to the lumen of the ...
Killylea (/ k ɪ l iː ˈ l eɪ /; from Irish Coillidh Léith 'grey forest') is a small village and townland in Northern Ireland. It is within the Armagh City and District Council area. The village is set on a hill, with St Mark's Church of Ireland , built in 1832, at its summit.
Consequently, the testes are located outside the body in a sac of skin called the scrotum. The optimal temperature is maintained at 2 °C ( man ) (8 °C mouse ) below body temperature. This is achieved by regulation of blood flow [ 20 ] and positioning towards and away from the heat of the body by the cremasteric muscle and the dartos smooth ...
In the Middle Ages, men who wanted a boy sometimes had their left testicle removed. This was because people believed that the right testicle made "boy" sperm and the left made "girl" sperm. [45] As early as 330 BC, Aristotle prescribed the ligation (tying off) of the left testicle in men wishing to have boys. [46]
These organs are located on the outside of the body, and within the pelvis. The main male sex organs are the penis and the scrotum, which contains the testicles that produce semen and sperm, which, as part of sexual intercourse, fertilize an ovum in the female's body; the fertilized ovum develops into a fetus, which is later born as an infant.
As luck would have it, “a structure in the brain called the dorsal raphe nucleus is strongly activated in orgasm, and that region is very much associated with production and distribution of ...
The epididymis (/ ɛ p ɪ ˈ d ɪ d ɪ m ɪ s /; pl.: epididymides / ɛ p ɪ d ɪ ˈ d ɪ m ə d iː z / or / ɛ p ɪ ˈ d ɪ d ə m ɪ d iː z /) is an elongated tubular genital organ attached to the posterior side of each one of the two male reproductive glands, the testicles.
The male reproductive system contains two main divisions: the testicles where sperm are produced, and the penis where semen is ejaculated through the urethra. In humans, both of these organs are outside the abdominal cavity. Having the testicles outside the abdomen facilitates temperature regulation of the sperm, which require specific ...
