Roof Of Frontal Bone

The floor of the frontal sinus is the roof of the orbit comprised of the frontal bone and lesser wing of the sphenoid.

Roof of frontal bone.

The anterior cranial fossa is a depression in the floor of the cranial base which lodges the frontal lobes of the brain. It is an irregular notch which articulates on either side of midline from medial to lateral wit. The orbital or horizontal part of the frontal bone forms the roof of the orbit and ethmoidal sinuses. Forms the rear of the skull temporal bones 2 bones.

Join together at the top of the head to form the top and sides of the cranial cavity occipital bone 1 bone. The squamous part of the frontal bone houses the frontal sinuses which are separated by a septum and are located above the orbits. Frontal process of maxilla and. This bone is part of the skull roof which is a set of bones that cover the brain eyes and nostrils.

4 frontal bone 1 bone. The anterior part of the bone articulates with the nasal bone and the prefrontal bone. Also contain the structures of the. At birth the human skull is made up of 44 separate bony elements.

Structures groove for superior sagittal sinus. It is a part of the bone projecting downwards below the glabella and between the supra orbital margins. The bones of the roof of the skull are initially separated by regions of dense connective tissue called fontanelles. The posterior part of the bone articulates with the postorbital bone and the parietal bone.

Lateral wall zygomatic process of the frontal bone orbital plate of the zygomatic bone orbital plate of the greater wings of sphenoid. The orbital part consists of two orbital plates separated by a gap the ethmoidal notch. During development many of these bony elements gradually fuse together into solid bone for example the frontal bone. There are six fontanelles.

Squamous part it is the largest one and encompasses the area of the forehead. Roof orbital plate of the frontal bone lesser wings of sphenoid. Forms the forehead and the roof of the eye sockets orbits parietal bones 2 bones. The neurocranium consists of two temporal bones situated to the base and side of the skull and two parietal bones that make up the roof of the skull.

The eight bones of the neurocranium form major portions of the skull and protect the brain. This part contains the supraorbital notch the superciliary arches the glabella and zygomatic processes. A pointed projection downward in the median plane from the lower part of the nasal. A single occipital bone forms the base of the skull and the frontal bone forms the forehead.

The frontal makes contact with several other bones in the skull. Medial wall frontal process of the maxilla lacrimal bone orbital plate of ethmoid bone body of sphenoid. Orbital emphysema is common when the frontal sinus is involved. Trauma to the frontal bar of the superior orbital rim can cause a buckling of this bone in addition to fractures of the contralateral orbit.

It comprises the frontal sinuses. The frontal bone is one of the skull bones enclosing the brain neurocranium and it consists of three parts.
