Posterior and lateral views of the skull
After completing this study unit you will be able to:
1. Identify the skull bones as seen from posterior and lateral views of the skull.
2. Name the sutures, canals, sulci and other structures seen from this perspective.
3. Identify the neurovascular structures that pass through the openings of the skull located on its lateral and posterior aspects.
The skull is comprised of 22 bones which are mostly connected to each other by fibrous joints, known as sutures. When the skull is observed from the lateral perspective, the most prominent bones are (anterior to posterior): the lateral aspects of the frontal bone, maxilla and mandible, zygomatic, sphenoid, temporal, parietal, and occipital bones.
When viewed from the posterior perspective, you can see the posterior aspect of the parietal bones, the squamous part of the occipital bone, posterior aspects of the maxilla and the mandible as well as some parts of the temporal and sphenoid bones.
This video tutorial will provide you with an overview of the lateral and posterior views of the skull.
