The term "petroccipital" is a combination of two anatomical terms: "petrous" and "occipital".
"Petrous" is derived from the Latin word "petrosus", meaning "rocky" or "hard". It refers to the petrous part of the temporal bone, located near the middle ear.
"Occipital" comes from the Latin word "occiput", meaning "back of the head". It refers to the occipital bone, which forms the lower, posterior part of the cranium.
When combined, "petroccipital" becomes an adjective used to describe structures or conditions related to both the petrous part of the temporal bone and the occipital bone.
