Skull Areas to Study
| Question | Answer |
|---|---|
| Sphenoid bone | sella turcica - LSORSO (foramen lacerum, foramen spinosum, foramen ovale, foramen rotunde, superior orbital fissure, optic canal); pterygoid processes are posterior to the teeth (see externally) |
| Mandible | the coronoid process is anterior to the mandibular condyle |
| Occipital | the basioccipital is directly anterior to the foramen magnum; the foramen most medial to the foramen magnum are the hypoglossal foramina (can only be seen internally) |
| Temporal | petrous portion (the ridge - seen internally) and the internal acoustic meatus which is contained there (anterior to the jugular foramen) |
| Cervical vertebrae | Axis: the Dens (odontoid) facet is anterior and superior to the vertebral foramen; C7: the elongated spinous process is called the cervical prominens; the spinous process on C2-C7 is bifid (forked); the Atlantoaxial joint is formed between Axis & Atlas |
| thoracic vertebrae | the vertebral arch is formed by the lamina (anterior to the spinous process) and the pedicle; the vertebral notch is the space where the superior articular facet from the inferior vertebra fits in |
| Scaupla - anterior view | spine not visible; subscapularis fossa visible; the coracoid process is anterior to the acromion process |
| Scapula - posterior view | the coracoid process is posterior to the acromion process; spine is visible; supraspinatus fossa visible above spine; infraspinatus fossa visible below spine |
| Skull - inferior view | review all foramen (note that you can see the LSO foramen in the sphenoid in this view) |
