  4. Cremaster muscle
  5. Internal spermatic fascia
  6. tunica vaginalis (visceral)
  7. tunica vaginalis (parietal)
24
Q

What are the 3 collaterals in the Testicular arterial circulation?

Q

What is the tunica albuginea?

A

The tough fibrous layer of connective tissue that surrounds the corpora cavernosa of the penis
Can also be referred to the connective tissue covering of the ovaries

A

The spongy layers that cover the urethra

Not involved in erection

Contains the deep dorsal vein of the penis

Surrounds the tunica albuginea

31
Q
