Symphysis
- 35—Hyoid Bone
Does not articulate with any other bone in the body
- 36—Orbit
- 37What seven bones compose the orbits?Frontal, Sphenoid,
Ethmoid, Maxilla,
Zygoma, Lacrimal, Palatine - 38Paranasal Sinusesair-filled cavities located in the frontal, ethmoid, and sphenoid bones of the cranium, as well as the maxillae of the face
- 39Maxillary sinuses are formed at:Birth
- 40Frontal and Sphenoid sinuses are formed at:6-7 years old
- 41Ethmoid sinuses are formed at:17-18 years old
- 42Which sinuses are the largest?Maxillary
- 435 Functions of Sinuses1. resonating chamber for the voice
2. decrease weight of skull
3. aid in warming/moisturizing inhaled air
4. act as shock absorbers in trauma
5. possibly control immune system - 44—
- 45Where are the ethmoid sinuses located?Within the labyrinths of the ethmoid bone
- 46—
