Understanding Ectocranial Anatomy: The Outer Layer of the Skull

Ectocranial refers to the outer layer of the skull, specifically the bony structures that form the periphery of the cranium. It is derived from the Greek words "ecto," meaning "outside," and "cranium," meaning "skull." The ectocranium includes the bones of the frontal, parietal, occipital, and temporal lobes, as well as the zygomatic process and the mastoid process. These bones form the outer surface of the skull and provide a protective covering for the brain.
