The smallest facial bones are the lacrimal bones.
These paired bones are delicate and roughly the size of a fingernail. They are located at the front part of the medial wall of each eye socket (orbit). The lacrimal bones play a crucial role in the tear drainage system.
Here's a breakdown of their characteristics and functions:
- Location: Situated in the medial wall of the orbit (eye socket).
- Articulation: They articulate (connect) with several other bones, including:
- Frontal bone
- Ethmoid bone
- Maxilla
- Inferior nasal conchae
- Function: Primarily involved in tear drainage. They contain the lacrimal groove, which helps form the nasolacrimal canal. This canal allows tears to drain from the eye into the nasal cavity.
In summary, the lacrimal bones are the smallest bones of the face and are essential for proper tear drainage, contributing to the overall health and function of the eyes.
