Head Injuries

Abstract

The brain is a soft structure within a protective, solid, bony skull, with a limited amount of space. It is stabilised by the falx cerebri and the tentorium cerebelli, and is cushioned by the cerebrospinal fluid. The brain is connected to the skull by the cerebral veins, which connect with the venous sinuses and brain drainage system. Very little movement is permissible within the skull but there is more in the antero-posterior plane than in the lateral because of the stabilising effect of the falx cerebri in the lateral plane of movement.
