Multiple Choice

Hydrocele is a serous fluid collection that accumulates between which two layers?

Fluid accumulates in the potential space between the visceral layer that covers the testis and the parietal layer lining the scrotal cavity. The tunica vaginalis surrounds the testis with these two layers, and a small amount of lubricating fluid is normal; when excess fluid builds up in that space, a hydrocele forms. The other depicted spaces aren’t the usual serous cavity involved—scrotal skin and tunica dartos form the superficial wall, and the space between the tunica albuginea and visceral layer isn’t the typical hydrocele cavity.
