Occipitomastoid suture
Occipitomastoid suture
The Occipitomastoid suture (pronunciation: /ɒksɪpɪtoʊˈmæstoʊɪd ˈsuːtʃər/) is a significant anatomical feature in the human skull.
Etymology
The term "Occipitomastoid suture" is derived from two Latin words: "Occipitalis," meaning "back of the head," and "Mastoideus," referring to the mastoid process of the temporal bone. The term "suture" comes from the Latin "sutura," meaning "seam."
Definition
