| Anatomical terms of muscle |
The dartos fascia is a layer of connective tissue found in the penile shaft and scrotum.[1]66 In addition to being continuous with itself between the scrotum and the penis, it is also continuous with Colles fascia of the perineum and Scarpa's fascia of the abdomen.[1]66
It lies just below the skin, which places it just superficial to the external spermatic fascia in the scrotum and to Buck's fascia in the penile shaft.
In the scrotum, it consists mostly of smooth muscle.[2] The tone of this smooth muscle is responsible for the wrinkled (rugose) appearance of the scrotum.[1]66
In females, the same muscle fibers are less well developed and termed dartos muliebris, lying beneath the skin of the labia majora.
It receives innervation from postganglionic sympathetic nerve fibers arriving via the ilioinguinal nerve and the posterior scrotal nerve. (http://anatomy.med.umich.edu/gastrointestinal_system/inguinal_tables.html)

Function
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.[1]66 It is also responsible for carrying the blood supply of the penile skin, a longitudinally-coursing anastamotic network of vessels that arise from the external pudendal vessels.[1]66
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 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.
The dartos muscle works in conjunction with the cremaster muscle to elevate the testis but should not be confused with the cremasteric reflex.
Related terms
Etymology:
- Derived from the Greek δέρνω/derno (beat, flog) and/or δέρμα/derma (skin), meaning "that which is skinned or flayed", possibly due to its appearance. [3]
Some dartos-related terms:
- dartoic (dar·to·ic) (dahr-to'ik) of the nature of a dartos; having a slow, involuntary contractility like that of the dartos.
- dartoid (dar·toid) (dahr'toid) resembling the dartos.
