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.
The pterion is a craniometric point at the point where the greater wing of the sphenoid bone, the parietal bone and the frontal bone meet. It is the weakest point of the skull.
Fontanelles are soft areas where the skull has not ossified to allow for brain growth and development. There are six fontanelles, with the anterior and posterior being the most prominent and clinically significant.
One of the weakest points on the human skull is the 'temple' region. This is known anatomically as the pterion (see the image above) and is formed by the junction of the frontal, parietal and sphenoid bones. Not only is it weak due to the number of bones converging here, but the bones themselves are very thin.
The position of the head also plays a role, because the skull is not equally strong throughout: The frontal bone is the strongest part of the skull, while the weakest bones are found in the temporal region.
What is the lacrimal bone? The lacrimal bone is one of the smallest and most fragile bones of the face. Despite its small size - a little bigger than the size of a fingernail - it has a complex anatomy, with several bony landmarks that are essential for the process of tear formation and secretion.
There are 22 bones in the human skull. The hardest bone in the human body is the jawbone.
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.
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.
We must remember that the most delicate organ in the human body is the brain. Brain is one of the largest and most complex organs of the human body and is made up of more than 100 billion nerves. Brain controls speech, thought, memory, movement and helps in the functioning of many organs in the human body.
When viewed in profile, female skulls have a rounded forehead (frontal bone). Male frontal bones are less rounded and slope backwards at a gentler angle. This ridge along the brow is prominent in males and much smoother in females.
Eight thin but incredibly strong bones make up the domed part of your skull. The bones lock together in joints called sutures that form wiggly lines. The frontal bone shapes your forehead and the top edge of your eye sockets.
About 72 J are required to penetrate the human skull and 250 J is absorbed by the human head in perforation by a 6 mm steel ball (6).
Treating minor head injuries
You can hold a cold compress to their head – try a bag of ice or frozen peas wrapped in a tea towel. Seek immediate medical advice if symptoms such as mild dizziness and a headache get worse.
The weakest and softest bone in the human is the clavicle or collar bone. Because it is a tiny bone which runs horizontally across your breastbone & collarbone, it is simple to shatter. Water makes up 31% of the weight of your bones.
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.
Answer and Explanation: This depends on the definition of 'hardest. ' The femur is thought to bear the most force, but the petrous bone on the skull is the densest bone in the body. The ability to break a human bone also depends upon other factors, like at what angle the force is applied or similar.
Abstract. 117 adult human skulls were classified for three morphological forms, i.e. dolichocephalic, mesocephalic and brachycephalic, and were examined for the presence of sutural bones in each form.
The clavicle, or collar bone, is the skin's softest and weakest bone.
Have you ever wondered what are the most common broken bones in the human body? Well, perhaps surprisingly, the most common bone to break is actually the clavicle, more often known as the collarbone. The clavicle is the bone that runs across the front of the body from shoulder to shoulder.
They found that as we age, bones in the skull shrink, sink and slide around.
