Abstract

Scalp is the soft tissue covering the vault of skull. Scalp proper extends from anterior to posterior as follows as glabella, superior orbital margin, frontozygomatic suture, superior temporal line, mastoid process, superior nuchal line, external occipital protuberance. From external to internal, scalp layers are skin, dense-connective tissue, epicranial aponeurosis or galea aponeurotica, loose areolar tissue, and pericranium. Thin skin has hair follicles and sebaceous glands, which are abundantly present. It is adherent to the dense-connective tissue layer and the aponeurotic layer. Hair is long and densely present. Each half of scalp is supplied by ten nerves. Anterior quadrant (in front of the auricle) is supplied by five nerves and the posterior quadrant (behind the auricle) is supplied by five nerves. Out of five nerves four are sensory nerves and one is a motor nerve.
