Frontal Bone
The structure indicated is the
frontal bone of the skull The frontal bone is one of 8 bones which form the calvaria (the part of the skull which contains the brain). The calvaria consists of:
- 2 parietal bones
- 2 temporal bones
- Frontal bone
- Sphenoid bone
- Ethmoid bone
- Occipital bone
The frontal bone consists of
three parts:
- Squamous part
- Orbital part
- Nasal part
The frontal bone articulates with the following bones:
- Sphenoid bones
- Ethmoid bone
- Parietal bones
- Nasal bones
- Maxillae bones
- Lacrimal bones
- Zygomatic bones
The point at which the frontal bones meet the parietal bones in the midline is called
bregma – this is where the
coronal suture is intersected by the
sagittal suture. The point at which the frontal bones meet the two nasal bones is known as
nasion. Learn more about the
bones of the skull in this tutorial.
