The lacrimal bone is a crucial facial bone that plays a key role in eye function.
Understanding the Lacrimal Bone
Here's a detailed look at the lacrimal bone, based on the provided information:
Location and Pairing
- The lacrimal bone is a paired facial bone. This means there are two of them, one on each side of the face.
- They are located in the medial wall of the orbit, which is the bony cavity containing the eyeball.
Function of the Lacrimal Bone
- Support for the lacrimal apparatus: The primary function of the lacrimal bone is to provide support for the lacrimal apparatus, which is the system responsible for producing and draining tears. This is crucial for keeping the eye lubricated and healthy.
- Muscle Attachment: The lacrimal bone serves as a site for the attachment of the orbicularis oculi muscle, which is involved in blinking and closing the eyelids.
