The soft tissue layers covering the top of the skull, including skin, dense connective tissue, and the muscle-tendon sheet of the forehead.
Structure
The scalp has five layers, easily remembered by the word SCALP: skin, connective tissue, aponeurosis, loose areolar tissue, and pericranium. The first three move together as a unit.
Function
The aponeurosis links the frontalis muscle in front to the occipitalis behind, letting the whole scalp slide over the skull when raising the eyebrows.
Clinical note
Cuts to the scalp bleed heavily because of its rich vascular supply, but heal well for the same reason.
