🗑
|
||||
| are the upper scroll-like bones on the lateral side of the nasal cavities. | middle and superior nasal conchae
🗑

🗑
|
||||
| the lower teeth, are anchored into bony sockets of the mandible | mandibular teeth
🗑
|
||||
| the articulation between the temporal bone and the mandible, lies just anterior to the external auditory meatus. dysfunction of this joint, due to misaligned teeth or teeth grinding/gritting can cause a great deal of pain | temporomandibular joint
🗑
|
||||
| can be felt about an inch inferior to the earlobe and its part of the mandible that bends in the bone. | angle
🗑
|
||||
| is the flat portion of the mandible which extends inferiorly from the temporomandibular joint to the angle of the mandible. | ramus
🗑
|
||||
| lateral to the maxilla. "the cheekbone" attaches to the zygomatic process of the temporal bone to complete the zygomatic arch on the side of the skull. | zygomatic bone
🗑
|
||||
| the final bone of the orbit is the tiny? lies at the medial aspect of the orbit and has a small opening into the lacrimal duct, which carries the tears from the eye to the nasal area. | lacrimal bone
🗑
|
||||
| are the most inferior of the scroll-like bones of the lateral nasal area. are formed from a separate bone than the superior/middle conchae. | inferior nasal conchae.
🗑
|
||||
| just posterior to the maxilla's portion of the palate, are two small bones. these two small bones form the posterior 1/4 of the hard palate. | palatine bones
🗑

||||
| superior to the palatine bones, within the nasal cavity is a small, wedge-shaped bone called? forms the inferior portion of the nasal septum. | vomer
🗑
