Superficial perineal pouch explained

Superficial perineal pouch
Latin:	compartimentum superficiale perinei or spatium superficiale perinei
Artery:	Branches of internal pudendal artery
Vein:	Branches of internal pudendal veins
Nerve:	Branches of perineal nerve
Lymph:	Superficial inguinal lymph nodes

The superficial perineal pouch (also superficial perineal compartment/space/sac) is a compartment of the perineum.

Structure

The superficial perineal pouch is an open compartment, due to the fact that anteriorly, the space communicates freely with the potential space lying between the superficial fascia of the anterior abdominal wall and the anterior abdominal muscles:

• its inferior border is the fascia of Colles, the deeper membranous layer of the superficial perineal fascia that covers the inferior border of the muscles of the superficial perineal pouch. (The fascia of perineum is a deep fascia that covers the superficial perineal muscles individually).
• its superior border is the perineal membrane (inferior fascia of the urogenital diaphragm).
