Study Notes
Skull Anatomy
- The lambdoid suture separates the parietal bones from the occipital bone.
- Nuchal lines are small ridges that extend laterally from the external occipital protuberance and serve as points of attachment for several neck muscles.
Bone Articulations
- The sphenoid bone articulates with the ethmoid, frontal, parietal, and occipital bones.
- The zygomatic arch consists of processes from the temporal and zygomatic bones.
- The mandibular bone articulates with the temporal bone.
Orbit and Palate
- The orbit is formed by the frontal, ethmoid, lacrimal, and maxillary bones.
- The hard palate is composed of the maxillary and palatine bones.
Foramina and Canals
- The foramen magnum is present in the occipital bone.
- The olfactory foramina are found in the cribriform plate.
- Sound waves en route to the eardrum travel through the external auditory meatus.
Unique Bones
- The hyoid bone does not articulate with any other bone.
- The mandible has the mandibular fossa, which articulates with the temporal bone.
Pituitary Gland and Nasal Septum
- The pituitary gland is located in the sella turcica.
- The nasal septum is comprised of the perpendicular plate of the ethmoid and the vomer.
Other Key Points
- The crista galli is a projection of the ethmoid bone.
- The alveolar process is the area that houses the teeth.
- The temporal bone contains ear structures.
