2. Tunica dartos
Skin of scrotum
- Thin
- Pigmented
- Covered with few hairs
Tunica dartos
Smooth muscle layer of scrotum
Tunica dartos function
Contraction causes scrotal skin to retract and draw testes toward body
Scrotal ligament connects
Tunica dartos to ligament of tail of epididymis
Scrotum location in cat
- Just ventral to anus
2. Lies dorsally on short, caudally directed penis
Each scrotal compartment contains?
- Testis

External abdominal oblique
Internal spermatic fascia derives from?
Transversalis fascia system
Layers of testes

- Scrotal lig.
(continuous)
Lig. of the tail of the epididymis attaches?

Mesorchium (visceral vaginal tunic)
Testicular bursa formed by?
Mesorchium (limited cranially and caudally by epididymis)
Ductus deferens enters the abdominal cavity at the?
Vaginal ring
Right and left ducts of ductus deferens enter?
Genital fold
Main blood supply to testis and epididymis
- Testicular a.
2. A. of ductus deferens
