Skull Cranial Bones
The skull is a bony case that protects the brain and the organs of special senses. It is further divided into the neurocranium and viscerocranium. The neurocranium or the braincase is composed of the cranial bones and its function is to house and protect the brain.
The viscerocranium is built by the facial bones and represents the skeleton of the face.
The cranial bones consist of two paired (temporal and parietal), and four single bones (frontal, occipital, sphenoid and ethmoid), joined together by immovable fibrous joints called sutures.
In this chapter, we will help you learn the basic anatomy of the skull by simplifying the concepts as much as we possibly can.

Frontal Bone Anatomy
The frontal bone is a cranial bone that surrounds and protects the anterior portion of brain. Learn about the different markings of the frontal bone.
Ethmoid Bone Anatomy
The ethmoid bone is a cuboid-shaped cranial bone that is located at the top of the nasal cavity, between the two orbits and it is anatomically divided into three parts: a horizontal cribriform plate, a perpendicular plate, and two ethmoidal labyrinths.
Parietal Bone Anatomy
The parietal bone is a large, thin, four-sided cranial bone that makes up much of the top and sides of the cranium. Learn about the different markings of the parietal bone.
Bones at the base of the skull
The base of the skull is the inferior part of the […]
Major Sutures of the Skull
Sutures are junctions between adjacent bones of the skull which are rigidly held together by fibrous connective tissue.
Fissures, foramina and markings of the base of the skull
The cranial floor bones support the inferior part of skull. Learn about the anterior markings of the tibia and fibula bones and test yourself.
Sphenoid Bone
The Sphenoid bone is a butterfly-shaped cranial bone that is located in the middle of the skull between the frontal and temporal bones.
Temporal Bone Anatomy
The temporal bones are facial bones which located at the sides and base of the skull, and lateral to the temporal lobes of the cerebral cortex.
Occipital bone: anatomy and landmarks
The occipital bone is an unpaired bone, which covers the back of the head. It is the only cranial bone to articulate with the cervical spine.
