This anatomical construction, discovered inside the flat bones of the cranium, designates a layer of spongy bone located between the inside and outer compact layers (cortices). For example, this specialised bone tissue is prominently noticed inside the parietal bone, the place it separates the interior and exterior tables of the cranial vault. Its distinctive structure contributes considerably to the general power and resilience of the cranium.
The importance of this characteristic lies in its position in dissipating forces and absorbing impacts, thereby defending the mind from traumatic harm. Moreover, it homes purple bone marrow, which is actively concerned in hematopoiesis, the method of blood cell formation. Traditionally, understanding its composition and performance has been essential in fields starting from forensic anthropology to neurosurgery, aiding in cranium fracture evaluation and surgical planning.
