In the human skull, the zygomatic bone (cheekbone or malar bone) is a paired irregular bone which articulates with the maxilla, the temporal bone, the sphenoid bone and the frontal bone….

‘ Many state that there is ‘no research’ supporting this idea. This statement is incorrect. However, there is much more research showing that there the bones of the head can than there is research showing that the bones of the head do not move. Much of this research is on the Cranial Academy’s web site.

Cranial bones can move small amounts, and do posses inherent rhythmic motion.

Clinical significance. The pterion is known as the weakest part of the skull. The anterior division of the middle meningeal artery runs underneath the pterion.

Some strength tests show the temporal bone in the skull to be the strongest bone. CONCLUSION: The thickest area of the skull is the parasagittal posterior parietal area in male skulls and the posterior parietal area midway between the sagittal and superior temporal line in female skulls.

Conclusion: The thickest area of the skull is the parasagittal posterior parietal area in male skulls and the posterior parietal area midway between the sagittal and superior temporal line in female skulls. An accurate map of the skull thickness representing the normative data of the studied population was developed.

It was concluded that occipital bone was the thickest skull bone, while frontal bone was found to be the second thickest skull bone. It was also noted that skull bones were not uniform plates and have great variations in thickness at different points.

The average skull thickness for men is 6.5 millimeters, and the average for women is 7.1 mm. The average front-to-back measurement is 176 mm for men and 171 mm for women, and the average width is 145 mm for men and 140 mm for women.

Turns out the human skull can withstand 6.5 GPa of pressure, while oak holds up under 11, concrete 30, aluminum 69 and steel 200. Atop the charts is graphene, which Mattei described as “a monolayer lattice form of carbon,” at 1,000 GPa.

Zygomatic bone

The occipital bone has a variety of functions. The most important role it plays is in protecting your brain. Specifically, it protects the brain’s visual processing center.

The occipital bone, atlas, and axis are responsible for most of the spine’s rotation, extension, and flexion—simply put, no other place in your spine moves more than the CVJ.

The occipital bone is a very complex bone that serves primarily to protect the cerebellum and the occipital lobes of the cerebrum and to provide attachment to several muscles and ligaments described below. It is trapezoidal and shallowly curved on itself.

The skull is not perfectly round or smooth, so it is normal to feel slight bumps and ridges. However, a dent in the head, especially if it is new, requires a trip to the doctor to determine the cause.

While it’s common for the shape of people’s skulls to vary, a new dent or irregularity in your skull can occasionally indicate a serious health condition. Dents in your skull can be caused by trauma, cancer, bone diseases, and other conditions.

Finding a bump on the head is very common. Some lumps or bumps occur on the skin, under the skin, or on the bone. There are a wide variety of causes of these bumps. In addition, each human skull has a natural bump on the back of the head.

The folds and ridges, that give the appearance of a brain on top of the head, is an indication of an underlying disease: cutis verticis gyrata (CVG). The rare disease causes a thickening of the skin on the top of the head which leads to the curves and folds of the scalp. “There are two forms of it (CVG).

Gorham-Stout disease (GSD), which is also known as vanishing bone disease, disappearing bone disease, massive osteolysis, and more than a half-dozen other terms in the medical literature, is a rare bone disorder characterized by progressive bone loss (osteolysis) and the overgrowth (proliferation) of lymphatic vessels.

As years pass, facial bones lose volume, contributing to the appearance of aging. Getting rid of facial wrinkles may not be enough to obscure the signs of aging. For a truly youthful look, you’d have to reshape the bones in your face, a study says.

Craniosynostosis is a congenital deformity of the infant skull that occurs when the fibrous joints between the bones of the skull (called cranial sutures) close prematurely. Due to this closure, the baby develops an abnormally shaped skull because the bones do not expand normally with the growth of the brain.

A skull reshaping surgery, also called cranioplasty, is a surgery designed to correct skull / cranium deformities. It is aimed at reshaping or correcting irregularities and/or imperfections of the skull.

Flat head syndrome usually happens when a baby sleeps with the head turned to the same side during first months of life. This causes a flat spot, either on one side or the back of the head. Flat head syndrome is also called positional plagiocephaly (pu-ZI-shu-nul play-jee-oh-SEF-uh-lee).

What is Normal? Parents spend so much time with their baby, recognizing an abnormal head shape can sometimes be difficult. We’ve found it can be helpful to see examples of a normal head shape before looking at abnormal ones. Normally, the head is about 1/3 longer than it is wide and rounded at the back.

Plagiocephaly (an asymmetrical head), scaphocephaly (a long narrow head) and brachycephaly (a short wide head) can occasionally cause problems for adults. These conditions are most commonly seen in children.

If your baby has a large flat spot that isn’t getting better by about 4 months of age, your doctor may prescribe a helmet. For a helmet to be effective, treatment should begin between 4 and 6 months of age. This will allow for the helmet to gently shape your baby’s skull as they grow.
