Suboccipital
Suboccipital
Suboccipital (pronunciation: suhb-uhk-SIP-i-tl) is a term used in anatomy to refer to the region located beneath the occipital bone of the skull. The term is derived from the Latin words 'sub', meaning 'under', and 'occipital', referring to the occipital bone.
Etymology
The term 'suboccipital' is derived from the Latin 'sub', meaning 'under', and 'occipital', which refers to the occipital bone. The occipital bone is named for its location at the back of the skull, from the Latin 'ob', meaning 'against', and 'caput', meaning 'head'.
Anatomy
The suboccipital region is home to the suboccipital muscles, which include the Rectus capitis posterior major, Rectus capitis posterior minor, Obliquus capitis superior, and Obliquus capitis inferior. These muscles are involved in the movement and stabilization of the head.
The suboccipital region also contains the suboccipital nerve, a branch of the C1 spinal nerve, which provides sensory and motor innervation to the suboccipital muscles.
