Ridges brain
WebThe human cranium, which houses and protects the brain, is composed of six major bones: the ethmoid, frontal, occipital, parietal, sphenoid and temporal. In normal development, the cranial bones remain separate until about age two. Then the separate cranial bones fuse together and remain that way throughout adulthood. The gyri are part of a system of folds and ridges that create a larger surface area for the human brain and other mammalian brains. Because the brain is confined to the skull, brain size is limited. Ridges and depressions create folds allowing a larger cortical surface area, and greater cognitive function, to exist in the confines of a smaller cranium. The human brain undergoes gyrification during fetal and neonatal development. In embryonic deve…
