SCALP
SCALP: Scalp is the soft tissue layer covering the bony vault over the brain. It is usually described as having five layers: S: Skin. The skin on the head from which head hair grows. It contains numerous sabaeceous glands and hair follicles C: Connective tissue. A thin layer of fat and fibrous tissue lies beneath the skin. A: Aponeurosis. The aponeurosis called epicranial aponeurosis (or galea aponeurotica) is the next layer. It is a tough layer of dense fibrous tissue which runs from the frontalis muscle anteriorly to the occipitalis posteriorly. L: Loose areolar tissue. The loose areolar connective tissue layer provides an easy plane of separation between the upper three layers and the pericranium. P: Pericranium. The pericranium is the periosteum of the skull bones and provides nutrition to the bone and the capacity for repair. Below the pericranium lies the 3 layers of the meninges, which are closely bounded to the brain. Meninges are already described in our previous post. •Written & published by: @nasarkhaan
