How porous is the skull?

Answer 1

The skull is not highly porous like some other bones in the body; it has a dense outer layer called the cortical bone, which provides strength and protection. However, the inner layer, known as trabecular or cancellous bone, contains small spaces that can be considered porous. While the skull does have some degree of porosity, it is primarily designed to protect the brain and maintain structural integrity. Overall, the porosity of the skull is relatively low compared to other bones.
