Anatomy Made Easy Inferior View Of The Skull Learn the different bony landmarks of the cranium, including the cranial foraminafor a full list of my available playlists and videos, please check out this. The frontal bone is one of the eight bones that make up the cranium – the superior aspect of the skull that encloses and protects the brain. its name is derived from the latin ‘frons’, meaning ‘forehead’. in this article, we shall look at the anatomy of the frontal bone – it’s location, structure, and clinical significance. fig 1.
5 Bony Landmarks Of The Head Skull Contents. there are several bony landmarks present in the anterior cranial fossa. the frontal bone is marked in the midline by a body ridge, known as the frontal crest. it projects upwards, and acts as a site of attachment for the falx cerebri (a sheet of dura mater that divides the two cerebral hemispheres). Lateral skull & inferior skull. creates a bridge like structure that connects the temporal bone with the zygomatic bone forming part of the zygomatic arch. above: markings of the cranium with the following views: (a) anterior view, (b) lateral view of the left side of the skull, (c) posterior view, and (d) lateral view of the right side of the. The 22nd bone is the mandible (lower jaw), which is the only moveable bone of the skull. figure 7.3.1 – parts of the skull: the skull consists of the rounded cranium that houses the brain and the facial bones that form the upper and lower jaws, nose, orbits, and other facial structures. Skull. introduction to the bones that make up the skull. the human skull consists of 22 bones (or 29, including the inner ear bones and hyoid bone) which are mostly connected together by ossified joints, so called sutures. the skull is divided into the braincase (neurocr anium) and the facial skeleton (viscerocranium).
Skull Bones Of The Cranium And Face The 22nd bone is the mandible (lower jaw), which is the only moveable bone of the skull. figure 7.3.1 – parts of the skull: the skull consists of the rounded cranium that houses the brain and the facial bones that form the upper and lower jaws, nose, orbits, and other facial structures.

The cranium, or skull, is the bony structure that protects the structures found inside our head, and it’s divided into two parts: the viscerocranium and the neurocranium. viscera refers to the organs within the body cavities, so the viscerocranium is the lower and anterior part of the skull that forms the orbits, the nasal cavities, and the. There are three cranial fossae with various structural landmarks. the anterior cranial fossa forms from the frontal bone, the sphenoid bone, and the ethmoid bone. the middle cranial fossa forms from the sphenoid bone and two temporal bones. finally, the posterior cranial fossa forms from the occipital bone and two temporal bones.
