The hardest bone in the human
Your thighbone (femur) is the longest and strongest bone in your body. Because the femur is so strong, it usually takes a lot of force to break it. Motor vehicle collisions, for example, are the number one cause of femur fractures.
' 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.
Human bone is 50 times lighter than steel which has the same strength. The human skull is made up of 22 bones. However, The jawbone is the toughest bone in the body.
The clavicle, or collar bone, is the skin's softest and weakest bone.
After diamonds, tooth enamel is the second hardest compound in the world. The hardest substance in the body is tooth enamel, your teeth's natural defence system. The only naturally occurring substance harder than tooth enamel is diamond.
The femur is the longest, strongest bone in your body. It plays an important role in how you stand, move and keep your balance. Femurs usually only break from serious traumas like car accidents.
An odd question; are teeth bones? Whilst your teeth and your bones may share some similarities, most notably in both being made of strong materials and sharing the same colour, they are not the same. Teeth are not made from bone. Bones are in a consistent cycle of being rebuilt and remade throughout your life.
The Stapedius, the smallest skeletal muscle in the human body, which is about 1 mm in length, is regarded to be the weakest muscle. It originates from a prominence known as the pyramidal eminence at the posterior edge of the tympanic cavity. It inserts into the stapes' neck.
The cranium, or skull, is composed of 22 bones anis d divided into two regions: the neurocranium (which protects the brain) and the viscerocranium (which forms the face).
A fracture of the upper arm or humerus may heal uneventfully in several weeks, while a fracture in the forearm takes much longer. The femur, or thighbone, is the longest and strongest bone in the body and difficult to break without major trauma.
Some people assume that fractured bones are more serious than broken bones, while others assume it's the other way around. But the truth is that these terms are used interchangeably, and they have the same meaning to medical professionals.
Your bones carry that weight every minute of every day as par for the course. Now, consider your teeth. Although paper-thin, the enamel that covers your teeth is much stronger than your bones. In fact, the only substance on earth that is stronger than enamel is diamond.
The femur is one of the most well-described bones of the human skeleton in fields ranging from clinical anatomy to forensic medicine. Because it is the longest and strongest bone in the human body, and thus, one of the most well-preserved in skeletal remains, it makes the greatest contribution to archaeology.
By comparison, rib bones show an unusual capacity to regrow and repair themselves even when a large portion is damaged.
Breaks of the lower leg (tibia and fibula) are the least common overall.
Diamond is the hardest known material to date, with a Vickers hardness in the range of 70–150 GPa. Diamond demonstrates both high thermal conductivity and electrically insulating properties, and much attention has been put into finding practical applications of this material.
For teens and other age groups, the most vulnerable teeth to cavities and decay are those in the back of your mouth. Known as molars or premolars, this category includes wisdom teeth—if you keep them in, that is.
An alloy of chromium, cobalt and nickel (CrCoNi) is the toughest material ever tested, and its characteristics could make it useful in the construction of aircraft or spacecraft.
