Bone features
bone features for the cranial and facial bones
| Question | Answer |
|---|---|
| External Auditory meatus of the temporal bone | tube like opening for the ear canal |
| mastoid process of the temporal bone | rounded projection posterior to external auditory meatus--also an attachment for muscles |
| styloid process of the temporal bone | long, thin projection on inferior skull surface--attachment for muscles and ligaments of tongue and neck |
| zygomatic process of the temporal bone | projection that articulates with the zygomatic bone |
| madibular fossa of the temporal bone | depression in mandible for articulation w/ condylar process |
| Foramen magnum of the occipital bone | opening where the spinal cord connects to the lower braing |
| occipital condyles of the occipital bone | rounded processes that articulate with the atlas |
| Cribriform plates of the ethmoid bone | one on eiether sid of the crista galli -- forms the roof of the nasal cavity |
| crista galli of the ethmoid bone | projection for attachment of membranes covering the brain |
| olfactory foramina of the ethmoid bone | tiny holes in the cribiform plates for cranial nerve 1 |
| perpendicular plate of the ethmoid bone | forms superior part of nasal septum |
| middle nasal conchae and superior nasal conchae of the ethmoid bone | scroll-like projections on each lateral wall of the nasal cavity |
| sella turcica of the sphenoid bone | cony projection that surrounds and protects the pituitary gland |
| optica foramina of the sphenoid bone | openings for cranial nerve 2 |
| alveoli of the maxilla bone | tooth sockets |
| palatine process of the maxilla bone | fused processes that form the anterior part of the hard palate |
| alveoli of the mandible bone | tooth sockets |
| body of the mandible bone | curved anterior portion of mandible |
| rami (ramus) of the mandible bone | posterior branches one on either side of the body of the mandible |
| condylar processes of the mandible bone | rounded processes on rami that articulate with temporal bone at teh mandibular fossa to form the TMJ |
| temporal process of the zygomatic bone | projects posteriorly-the temporal process of the zygomatic bone and the zygomatic process of the temporal bone together make the zygomatic arch |
