How do Rams headbutt each other multiple times without getting brain damage or seriously injured?
In: Biology
During a head injury damage to the brain occurs primarily as a result of movement of the brain within the skull and impacting the inside of the skull surface, causing damage at the site of each impact, known as a coup and contrecoup contusion. This is due to the layer of cerebrospinal fluid between the surface of the brain and the inside of the skull. Sheep, Bison and other animals that engage in similar head-butting behavior have significanlty less cerebrospinal fluid between the brain surface and the inside of the skull, resulting in less linear movement of the brain during an impact therefore less force is exerted upon the brain.
