What is the fascia of the abdomen?
Abdominal fascia refers to the various types of fascia found in the abdominal region. Fascia is a sheet of connective tissue that is found beneath the skin that attaches, stabilizes, encloses, and separates muscles and other internal organs.

What are the different types of fascia?
There are three main types of fascia:
- Superficial Fascia, which is mostly associated with the skin;
- Deep Fascia, which is mostly associated with the muscles, bones, nerves and blood vessels; and.
- Visceral (or Subserous) Fascia, which is mostly associated with the internal organs.
What does camper’s and Scarpa’s fascia refer to?
Superficial fascia is composed of two layers: the fatty outer layer, known as Camper’s fascia, and the more membranous inner layer, called Scarpa’s fascia. These parts of the superficial fascia are most prominent in the lower aspect of the abdominal wall below the level of the umbilicus.
What is the perineal fascia?
