Pterion
- The frontal, parietal, temporal and sphenoid bones unite at the ‘pterion’ – the thinnest part of the skull.
- The middle meningeal artery runs in a groove on the inner table of the skull in this area.
Where is the thickest part of the skull?
parasagittal posterior parietal area
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.
Is your temple a weak spot?
Due to the nature of this arrangement, it is considered to be the weakest part of the skull. In addition to this area being weak, there is also a major cranial artery that runs underneath: middle meningeal artery.
How thick is the thickest part of the skull?
… Human male skulls vary in thickness from 3.9 mm to 9.35 mm, in the occipital region (Mahinda and Murty, 2009). In females, the occipital skull thickness varies from 3.44 mm to 8.2 mm (Mahinda and Murty, 2009 ). Moss et al.
How thin is the skull?
The average thickness of a male skull was 0.25 inches (6.5 millimeters), while the average thickness of a female skull was 0.28 inches (7.1 millimeters).
Which part of the skull is strongest?
Your mandible, or jawbone, is the largest, strongest bone in your face.
How thick is the skull at the forehead?
The mean calvarial thickness is 6.8 to 7.7 mm, which can be safely drilled to a depth of 3-4 mm. The bone is thicker in the female than in the male, and the thickest is in the parietal bone behind the coronal suture; the superotemporal site is thinnest, with a thickness between 4.71 and 6.14 mm.
What is the weakest part of the skull?
The pterion
The pterion is known as the weakest part of the skull. The anterior division of the middle meningeal artery runs underneath the pterion. Consequently, a traumatic blow to the pterion may rupture the middle meningeal artery causing an epidural haematoma.
What happens if you hit your temple to hard?
Answer: Yes you could: there’s a very dangerous spot on your head where the bone is very thin, and underneath that there is an artery called the middle meningeal artery, so if you do get hit there it can damage the artery and you could get a brain bleed.
What is under your temple?
The temple is a latch where four skull bones fuse: the frontal, parietal, temporal, and sphenoid. It is located on the side of the head behind the eye between the forehead and the ear.

Are all skulls the same thickness?
According to a new imaging study of 3,000 people using the latest in imaging analysis techniques, women’s skulls are thicker than men’s, and both shrink slowly in adulthood. The average skull thickness for men is 6.5 millimeters, and the average for women is 7.1 mm.
What human has the thickest skull?
John Ferraro is the Hammerhead. His skull is more than two times thicker than the average human’s, and he uses it to hammer nails into wood, snap baseball bats in half, and bend steel bars!
How thick is a gorilla skull?
In fact, the average male gorilla’s skull is 16 cm high, 34 cm long, and 18 cm wide.
Are female skulls thicker?
Summary: Women’s skulls are thicker than men’s, but they both shrink slowly after we reach adulthood. That’s the conclusion of a new imaging study of 3000 people. The detailed results could help in the design of more effective devices for protecting the head in vehicle collisions and other accidents.
Do some people have thicker skull?
Powerfully built individuals may in fact have rather thin cranial vaults, whereas small, slightly built people may have thick skulls. Since the degree of cranial fracturing due to external force has been related to cranial thickness and bone structure (see e.g. Gurdjian et al.
Why are male skulls thicker than females?
The key difference between male and female skull is that male skull is heavier due to the presence of thicker bones while female skull is lighter due to the presence of thinner bones.
What is the most vulnerable part of the head?
We find that head angular acceleration and brain tissue strain resulting from an input force can vary by orders of magnitude based on impact location on the skull, with the mandible as the most vulnerable region.
What bone is hardest to break?
The thigh bone is called a femur and not only is it the strongest bone in the body, it is also the longest. Because the femur is so strong, it takes a large force to break or fracture it – usually a car accident or a fall from high up.
Where are the most fragile bones in the face?
The pair of bones, one in each eye socket, sits at the front of the orbit, near the corner of the eye, closest to the nose. Supporting the eye, the lacrimal bones are the most fragile of the 14 facial bones. The orbital surface of the lacrimal bone is divided by a ridge called the posterior lacrimal crest.
Is everyone’s skull the same size?
Human skulls look different depending on if they are male or female, and depending on what part of the world they come from. While we all have the same 22 bones in our skulls, their size and shape are different depending on sex and racial heritage.
How hard is the human skull?
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.
