Is it normal to have an occipital bun?

Is it normal to have an occipital bun?

Occipital spurs, also called as occipital knob, occipital bun, chignon or inion hook, is an exaggerated external occipital protuberance (EOP). It is frequently discussed in anthropological literature as a Neanderthal trait but hardly reported and considered as a normal variant in medical literature.

Does everyone have occipital bun?

There are still many human populations which often exhibit occipital buns. A greater proportion of early modern Europeans had them, but prominent occipital buns even among Europeans are now relatively infrequent. Bushmen from South Africa and Australian aborigines often have occipital buns also.

What causes occipital buns?

A study conducted by Lieberman, Pearson and Mowbray provides evidence that individuals with narrow heads (dolichocephalic) or narrow cranial bases and relatively large brains are more likely to have occipital buns as a means of resolving a spatial packing problem.

Can you feel your occipital bone?

The bony skull bump — known as an external occipital protuberance — is sometimes so large, you can feel it by pressing your fingers on the base of your skull.

Why is my occipital bone so big?

The bony growth, which is known as an “external occipital protuberance,” can be found at the back of the skull, just above the base of the neck. The introduction to the study for Nature stated the growth development may be an “adaptive mechanism” to handle “frequent tensile stress” at the tendon and bone site.

Where is the occipital ridge?

The occipital ridge is the region at the back of the head where the base of the skull meets the spine.

What is the hard lump on the back of my head?

In addition, each human skull has a natural bump on the back of the head. This bump, called an inion, marks the bottom of the skull where it attaches to the neck muscle.

Can occipital neuralgia be cured?

Treatment of occipital neuralgia aims to alleviate the pain; however, it is not a cure. Interventions can be surgical or non-surgical.

Where is the occipital bone located?

Occipital bone location is the back of the head; the Latin term occiput specifically refers to this region. Also known as C0 because it forms one side of the atlanto-occipital joint between the cranium and first cervical vertebra (C1), this bone runs from the base to approximately halfway up the skull.

Where is the occipital located?

skull
The occipital lobe is located at the rear portion of the skull, behind the parietal and temporal lobes. One of the most important parts of this lobe is the primary visual cortex, a region of the brain that receives input from the retina of the eye.

Is it normal to have a knot on the back of your head?

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.

Is it normal to have an indent in the back of your head?

The takeaway 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.

Is your head shaped like an occipital bun?

Is your head shaped like the example on the left or the right? An occipital bun is a prominent bulge or projection of the occipital bone at the back of the skull. It is important in scientific descriptions of classic Neanderthal crania. This term has not been translated into most languages yet as it is rare amongst people today.

Are occipital buns related to the biomechanics of running?

While common among many of humankind’s ancestors, primarily robust relatives rather than gracile, the protrusion is still relatively prevalent in modern Homo sapiens. It is suspected that occipital buns might correlate with the biomechanics of running.

Was the occipital bun inherited from the Neanderthal admixture?

The occipital bun is common among all Europeans, especially northern Europeans. It is virtually absent in other populations. Neanderthal had one too, which led me to think that this was among the traits that Europeans inherited from the Neanderthal admixture.
