Facial bones are the bones that make up the structure of the face. There are 14 facial bones, each with specific functions and characteristics.
1. Nasal bones: These are two small bones that form the bridge of the nose and support the cartilage that shapes the nose.
2. Maxilla: The maxilla is the upper jaw bone that forms the upper part of the mouth and supports the upper teeth.
3. Zygomatic bones: Also known as the cheekbones, these bones form the prominence of the cheeks and help to protect the eyes.
4. Mandible: The mandible is the lower jaw bone that holds the lower teeth in place and allows for movement of the jaw.
5. Lacrimal bones: These are two small bones located near the inner corner of the eye that help to form the eye socket.
6. Palatine bones: The palatine bones are located at the back of the mouth and help to form the hard palate.
7. Inferior nasal conchae: These are thin, scroll-like bones located inside the nasal cavity that help to filter and humidify air as it passes through the nose.
8. Vomer: The vomer is a thin, flat bone located in the nasal cavity that helps to separate the left and right nasal passages.
9. Hyoid bone: The hyoid bone is a U-shaped bone located in the neck that supports the tongue and helps with swallowing and speech.
Each of these facial bones plays a crucial role in supporting the structure of the face, protecting the delicate organs of the head, and allowing for important functions such as breathing, eating, and speaking.

## Types and Functions of Facial Bones
Facial bones can be categorized into two main groups:
### 1. Cranial Bones
Types:
- Frontal bone
- Parietal bones (2)
- Temporal bones (2)
- Occipital bone
- Sphenoid bone
- Ethmoid bone
Functions:
- Enclose and protect the brain (cranial cavity)
- Provide attachment sites for muscles of the scalp and face
- Form the roof (calvaria) and sides of the skull
### 2. Facial Bones
Types:
Upper Jaw (Maxilla) and Palate:
- Maxilla (2)
- Palatine bones (2)
Nose and Paranasal Sinuses:
- Nasal bones (2)
- Inferior nasal conchae (2)
- Middle nasal conchae (2)
- Superior nasal conchae (2)
- Cribriform plate (part of ethmoid bone)
- Lacrimal bones (2)
- Zygomatic bones (2)
Orbits (Eye Sockets):
- Frontal bone (part of the orbit)
- Lacrimal bones (part of the orbit)
- Ethmoid bone (part of the orbit)
- Sphenoid bone (part of the orbit)
- Zygomatic bones (part of the orbit)
Mandible (Lower Jaw):
- Mandible
Other:
- Vomer bone
- Turbinate bones (inferior, middle, and superior nasal conchae)
Functions:
- Provide support and shape to the face
- Form the oral and nasal cavities
- Anchor teeth
- Facilitate breathing, olfaction (smell), and mastication (chewing)
- Protect the eyes, paranasal sinuses, and brain
- Provide attachment sites for muscles of facial expression
