Dartos: Difference between revisions

Line 61:

In the penis, the loose attachment of the dartos fascia to Buck's fascia is responsible for the high degree of mobility of the penile skin over the underlying tissue.<ref name=Campbell10 /> It is also responsible for carrying the blood supply of the penile skin, a longitudinally-coursing anastomotic network of vessels that arise from the external pudendal vessels.<ref name=Campbell10 />

In the scrotum, the tunica dartos acts to regulate the [[temperature]] of the ~~[[testicle]]s~~, which promotes [[spermatogenesis]]. It does this by expanding or contracting to wrinkle the scrotal skin.

In the scrotum, the tunica dartos acts to regulate the temperature of the testicles, which promotes spermatogenesis. It does this by expanding or contracting to wrinkle the scrotal skin.

* Contraction reduces the ~~[[area|~~surface area]] available for heat loss, thus reducing [[heat]] loss and warming the testicles.

* Contraction reduces the surface area available for heat loss, thus reducing heat loss and warming the testicles.

* Conversely, expansion increases the surface area, promoting heat loss and thus cooling the testicles.
