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. Your bones are four times more powerful than a concrete pound for pound.
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. To fix it properly requires an operation.
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.
Your femur is the largest bone in your body. Most adult femurs are around 18 inches long. The femur is also the strongest bone in your body. It can support as much as 30 times the weight of your 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. Due to its length and slenderness, as well as its prominent position, it breaks quite easily.

Teeth and bones look similar and share some commonalities, including being the hardest substances in your body. But teeth aren't actually bone. This misconception might arise from the fact that both contain calcium. More than 99 percent of your body's calcium can be found in your bones and teeth.
The skull protects the brain and forms the shape of the face. The spinal cord, a pathway for messages between the brain and the body, is protected by the backbone, or spinal column.
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.
The pain is worse if the bone breaks the skin. A broken collarbone can take up to eight weeks to heal. The good news is you can usually recover by just wearing a sling, though sometimes surgery is required. A broken tailbone (coccyx) is extremely painful because it restricts many activities.
The human body consists of over 600 muscles. Human bone is as strong as steel but 50 times lighter.
Fat is generally considered to be the softest tissue. Soft tissues are distributed throughout the body and come in many types, including muscle, fat, blood, fibrous tissue, and lymphatic vessels. The main function of these soft tissues is to buffer, surround, support, and provide links between tissues in the body.
Evel Knievel (USA, b. Robert Craig Knievel), the pioneer of motorcycle long jumping exhibitions, had suffered 433 bone fractures by end of 1975.
An adult human consists of 206 bones in the body, whereas a baby has 300 bones in the body. As the baby grows the bones come to have fused and the total number of bones is reduced. The bones stop growing approximately at the age of 25.
Most blood cells are made in your bone marrow. This process is called haemopoiesis. In children, haemopoiesis takes place in the long bones, like the thighbone (femur). In adults, it's mostly in the spine (vertebrae) and hips, ribs, skull and breastbone (sternum).
Small holes in the skull bones, called foraminae, enable blood vessels, such as the carotid arteries and nerves, to enter and leave the skull. The spinal cord passes through the largest hole, called the foramen magnum, in the base of the cranium to join the brain.
Non-White or Yellow Teeth are Unhealthy
Teeth whitening treatments usually work by stripping or entering the outer enamel layer, which makes teeth weaker if done many times. So, more often than not, yellow teeth are actually stronger than pearly white ones–so long as they're cleaned regularly.
Sharks do not have bones.
Their cartilaginous skeletons are much lighter than true bone and their large livers are full of low-density oils, both helping them to be buoyant. Even though sharks don't have bones, they still can fossilize.
What Can Be Done to Whiten Yellow Teeth? If you're looking for a radical change in the coloring of your teeth, you need professional-grade whitening to get the job done. Your cosmetic dentist can provide treatment that penetrates deep into the enamel and removes years of stains with a powerful bleaching agent.
The clavicle, or collarbone, is also referred to as “beauty bone” because of its prominent body location.
Fact 7: The Toe Bones are the Most Fragile in our Body
Most people end up breaking a toe in their lifetime.
Once your broken bone heals fully, it should be just as strong as the rest of your bones, so you won't be more or less likely to break it than another bone.
