Study Notes
Superficial Fascia Overview
- Comprised of two layers: superficial fatty layer (Camper's fascia) and deep membranous layer (Scarpa's fascia).
- Superficial fatty layer is continuous with general body fat and can be notably thick in obese individuals, exceeding 3 inches (8 cm).
Membranous Layer Characteristics
- Thin layer that diminishes laterally and superiorly, merging with superficial fascia of the back and thorax.
- Inferiorly, it extends onto the thigh, fusing with deep fascia about one fingerbreadth below the inguinal ligament.
- In the midline, it does not attach to the pubis; instead, it forms a tubular sheath around the penis or clitoris.
Extensions and Connections
- Below, in the perineum, it integrates into the scrotal wall (or labia majora) and connects to the margins of the pubic arch, known as Colles' fascia.
- Posteriorly, this layer fuses with the perineal body and the back edge of the perineal membrane.
Special Features in the Scrotum
- In the scrotal region, the fatty layer transforms into a thin layer of smooth muscle called the dartos muscle.
- The membranous layer remains distinct and serves specific functions in surrounding structures.
