Questions and Answers
Match the following bones with their anatomical division in the skull:
Frontal, Occipital, Parietal = Cranial roof Frontal, Sphenoid, Ethmoid, Occipital, Parietal, Temporal = Cranial base Skull = Bony structure supporting the face and protecting the brain Sutures = Unique fibrous joints in the skull
Match the following actions with their description:
Supports the face = Function of the bony structure of the skull Protects the brain = Function of the cranium Articulates with the 1st cervical vertebra, facial bones, and mandible = Function of the cranial base Unique to the skull = Characteristic of sutures
Match the following terms with their description:
Neurocranium = Encloses and protects the brain, meninges, and cerebral vasculature Viscerocranium = Anatomical division of the facial bones Calvarium = Also known as the cranial roof Sphenoid, Ethmoid, Temporal = Bones comprising the cranial base

Study Notes
Skull Bones and Divisions
- Cranial bones belong to the neurocranium division
- Facial bones belong to the viscerocranium division
- Neurocranium protects the brain
- Viscerocranium forms the face
Bone Articulations
- Bones articulate with each other at joints
- Joints allow for movement and flexibility in the skull
Anatomical Actions
- Elevation: upward movement, e.g., looking up
- Depression: downward movement, e.g., looking down
- Protraction: forward movement, e.g., sticking out the jaw
- Retraction: backward movement, e.g., pulling in the jaw
- Lateral rotation: rotating the head side to side
- Medial rotation: rotating the head toward the midline
Anatomical Terms
- Sagittal: relating to the midline, e.g., sagittal suture
- Coronal: relating to the crown, e.g., coronal suture
- Frontal: relating to the forehead
- Parietal: relating to the side of the head
- Occipital: relating to the back of the head
