The hardest bone in the human body is the jawbone. The human skeleton renews once in every three months. The human body consists of over 600 muscles. Human bone is as strong as steel but 50 times lighter.
Without any doubt, medical sciences have claimed that the longest and strongest bone in your body is the thigh bone or femur. Because it's so strong, it usually takes a severe force or impacts like a fall or car accident to break your femur.
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.
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.
#1 Most Commonly Broken Bone
The clavicle, also known as the collarbone, is the most common bone that is broken. It is located between the shoulder blade and upper ribcage. The collarbone is slender and positioned in a way that makes it easy to break in sports activities and car accidents.
Breaks of the lower leg (tibia and fibula) are the least common overall.
Your teeth are made up of about 96% mineral. Because they are almost entirely made up of solid mineral, this makes them stronger than your bones. This is also because there is no living tissue in your hard enamel layers. Your bones have living, soft tissues in them, which makes them a bit weaker than your teeth.
The softest part is most likely the brain. It is the part that is most changeable due to external influences, and so, it is the "softest". Brain is the most delicate and soft organ of the human body.
While a broken finger might be a slight annoyance for a couple of weeks, a severe femur fracture can have you off your feet for more than six months.
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.
By comparison, rib bones show an unusual capacity to regrow and repair themselves even when a large portion is damaged.
The strongest muscle based on its weight is the masseter. With all muscles of the jaw working together it can close the teeth with a force as great as 55 pounds (25 kilograms) on the incisors or 200 pounds (90.7 kilograms) on the molars.
Are bones stronger than concrete? Well, it depends. Nature has been optimizing our bone structures for millennia. Bone typically has an elastic modulus that is like concrete but it's 10 times stronger in compression.
People lose bone mass or density as they age, especially women after menopause. The bones lose calcium and other minerals. The spine is made up of bones called vertebrae.
Enamel on our teeth is the strongest material in the human body; keratin is softer than enamel, thus you can scratch your fingernails with your teeth, but not other areas of your body with your fingernail. Keratin or fingernails is the second hardest material in the human body.
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 gums are part of the soft tissue lining of the mouth. They surround the teeth and provide a seal around them. Unlike the soft tissue linings of the lips and cheeks, most of the gums are tightly bound to the underlying bone which helps resist the friction of food passing over them.
So why won't teeth heal themselves? When compared to bones – which have plenty of blood vessels running through them – tooth enamel doesn't have any way to get fresh oxygen and nutrients. This means that once it's damaged, your tooth can't repair itself like other parts of your body can.
Despite this, while not being considered bones, teeth usually are considered part of the skeletal system, because of their close functional association with the mandible and maxilla of the skull.
Comminuted fracture
This type of fracture requires a lot of force, which causes your bone to break into several pieces. A comminuted fracture typically brings very intense pain. Because the fracture is in several pieces, surgery is usually required to fix it.
A boxer's fracture is a break in the neck of the 5th metacarpal bone in the hand. It usually happens when you punch an object at a high speed. Symptoms of a boxer's fracture include pain and swelling of the hand, limited range of motion of the pinky finger, and misalignment of the finger.
Transverse Fracture
This is when a bone breaks clean and straight across. This is one of the simplest types of broken bones and one of the easiest to correct and heal.
