|Applied Anatomy of the Scalp|
1. The scalp enjoys a rich blood supply in which there is an exentesive antero-posterior and right-left anastomosis.
2. The veins of the scalp are connected to the intracranial venous sinuses by emissary veins. Therefore
3. The aponeurosis connects the frontalis and occipitalis muscles. If it is cut coronally. contraction of the muscle
4. The layer of loose connective tissue constitutes the plane of avulsion. The superficial three layers usually peel
5. The pericranium, that is the periosteum of the skull bones is tightly adherent to the sutures. Accordingly,
Applied anatomy of the Skull
|1. The skull has weak points e.g.
These points are easily fractured causing injury to the underlying organs.
2. In fractures of cribriform plate and petrous temporal bone, meninges and mucous membranes may be torn
3. The foramina have rigid boundaries. So , in space occupying lesions, contents of the foramina are often
4. Abscence of diploe in babies facilitates moulding.
5. Fontanelles and sutures in newborns permit brain growth, delayed closure suggests retarded skeletal
