Anterior view of the skull
After completing this study unit you will be able to:
- Name the bones that can be seen in an anterior view of the skull.
- Describe the viscerocranium and the neurocranium.
- Identify the relationship between the special sensory organs and the anterior skull.
The skull is divided into two parts, the viscerocranium and the neurocranium. The viscerocranium simply refers to the bones that form the facial skeleton. The neurocranium refers to the bones that house and protect the brain.
The viscerocranium is made up of 14 irregular bones, which can be seen in an anterior view of the skull. It’s important to note, though, that some anatomists consider the mandible to be a bone of the viscerocranium whilst others do not (classifying it as an extracranial bone instead). These bones provide housing for many of our special senses; our eyes (sight), nose (smell) and our mouth (taste). The facial bones of the anterior skull also provide openings for the intake of food, water and oxygen.
