The scalp is composed of soft tissue layers that cover the cranium. It is an anatomic region bordered anteriorly by the human face, and laterally and posteriorly by the neck. It extends from the superior nuchal lines and occipital turbulences to the supraorbital foramen. Aesthetically, it serves as an area where hair can grow and physically, as a barrier that defends the body from foreign irritation. There are five layers to the scalp: the skin, connective tissue layer, galea aponeurotica, loose areolar connective tissue, and the pericranium.
