Study Notes
Skull Bone Markings and Functions
- Cranial bones:
- Frontal bone: forms forehead, superior part of orbits, and most of the anterior cranial fossa; contains sinuses
- Parietal bone: forms most of the superior and lateral aspects of the skull
- Occipital bone: forms posterior aspect and most of the base of the skull; contains foramen magnum, hypoglossal canals, and occipital condyles
- Temporal bone: forms inferolateral aspects of the skull and contributes to the middle cranial fossa; has squamous, tympanic, and petrous parts
- Sphenoid bone: forms the keystone of the cranium; contributes to the middle cranial fossa and orbits
- Ethmoid bone: forms part of the nasal septum and the lateral walls and roof of the nasal cavity; contributes to the medial wall of the orbit
Facial Bones
- Nasal bones: form the bridge of the nose
- Lacrimal bones: form part of the medial orbit wall; contain lacrimal fossa
- Zygomatic bones: form the cheek and part of the orbit
- Inferior nasal conchae: form part of the lateral walls of the nasal cavity
- Mandible: the lower jaw; contains coronoid processes, condylar processes, mandibular symphysis, dental alveoli, and mandibular foramina
- Maxilla: forms the upper jaw and parts of the hard palate, orbits, and nasal cavity walls
- Palatine bones: form the posterior part of the hard palate and a small part of the nasal cavity and orbit walls
- Vomer: forms the inferior part of the nasal septum
- Auditory ossicles: involved in sound transmission in the middle ear cavity
