The orbital or horizontal part of the frontal bone (pars orbitalis) consists of two thin triangular plates, the orbital plates, which form the vaults of the orbits, and are separated from one another by a median gap, the ethmoidal notch.

Nov 3, 2023 · By definition, the orbit (bony orbit or orbital cavity) is a skeletal cavity comprised of seven bones situated within the skull. The cavity surrounds and provides mechanical protection for the eye and soft tissue structures related to it.

Jul 24, 2023 · The medial orbital wall consists of four bones, the frontal process of the maxillary bone: the lacrimal bone, the orbital plate of the ethmoid bone, and the lesser wing of the sphenoid bone. The largest part of the medial wall is from the ethmoid bone.

Orbital plate may refer to: Orbital part of frontal bone; Orbital lamina of ethmoid bone

Mar 14, 2025 · : a thin plate of bone forming the lateral wall enclosing the ethmoidal air cells and forming part of the side of the orbit next to the nose

The medial wall is formed primarily by the orbital plate of ethmoid, as well as contributions from the frontal process of maxilla, the lacrimal bone, and a small part of the body of the sphenoid. It is the thinnest wall of the orbit, evidenced by pneumatized ethmoidal cells.

Jul 25, 2023 · The frontal bone consists of six main parts: the squamous part, nasal part, two orbital plates and two zygomatic plates. The main function of the frontal bone is to create the smooth curvature of the forehead and to provide protection for the frontal lobe of the brain.

This anatomical illustration depicts a sagittal view of the bony structures of the medial wall. Key landmarks include the frontal process of the maxillary bone, ethmoid bone, orbital plate of the frontal bone, and optic foramen.

The orbital part of frontal bone, also known as pars orbitalis, is the horizontal portion of the frontal bone that stretches back from the supraorbital margin. It is made up of two thin triangular plates, known as the orbital plates.

The orbital plate of frontal bone is a triangular-shaped bony plate that makes up the roof of the orbital eye socket. The two orbital plates, one on each side, are separated from each other by an ethmoidal notch in the middle.
