Orbital part

Orbital Part

The Orbital Part is a component of the Frontal bone in the human skull. It is one of the two parts of the frontal bone, the other being the Squamous part. The orbital part is located in the anterior, or front, of the skull and forms the upper part of the eye socket, or orbit.

Structure

The orbital part is thin and translucent. It is quadrilateral in shape and has smooth, convex surfaces. The edges of the orbital part articulate with the parietal, sphenoid, and ethmoid bones.

The orbital part is responsible for protecting the eye and its associated structures. It also provides a surface for the attachment of muscles that move the eye and eyelid.

Clinical significance

Due to its location and thinness, the orbital part is susceptible to fractures, particularly from blunt force trauma to the face. Such fractures, known as orbital fractures, can lead to complications such as diplopia (double vision), enophthalmos (sunken eye), and orbital cellulitis.
