10 interesting things about the human skeleton

The adult skeleton consists of 206 units, connected to a network, performing many functions such as shaping the body frame, supporting movement and producing new blood cells.

The newborn baby's skeleton contains about 300 components, a mixture of bone and cartilage.The cartilage will gradually harden to become bone in a process called osteogenesis.Over time, the number of "plus" bones in unified babies forms larger bones, reducing the number of bones to 206 when reaching adulthood.

Bones are not evenly distributed throughout the body.They focus mainly on hands and feet.Each hand has 27 bones and each foot has 26 pieces.In total, two hands and two feet have 106 bones, accounting for more than half of the bones in the human body.(Photo: Shutterstock)

Nail bone is a bone shaped horseshoe in the throat, between the chin and cartilage.This is the only bone in the body that is not connected to any other bone.Nail bones combine with larynx and tongue to create human voices (Photo: Null)

Bone is made up of active living cells.Therefore, it also has the ability to develop benign tumors and even cancer.In 2013, scientists found a tumor in the Neanderthal's ribs, dating from 120,000 to 130,000 years.This is the oldest human tumor ever discovered.(Photo: Shutterstock)

Vertebrate animals only account for 2% of the total animal population on Earth.98% of the remaining species are invertebrates, such as insects, spiders and mollusks.(Photo: Rob Robbins)

Bone is strong and hard, even harder than steel.However, they are not the most rigid structure in the body.This taste belongs to another part of the tooth enamel layer (concentrating high concentrations of minerals, mainly calcium salts).(Photo: Stoughtondental)

People have known how to treat bone fractures thousands of years ago.In the book Edwin Smith Papyrus from ancient Egypt (about 1,600 BC) the author describes the treatment of fractures, including a broken arm.The book states that we need to rearrange the bones in place and then bandage the wound with linen.(Photo: Joseph Castro / Live Science)

About 3,000 years ago, the ancient Egyptians created the first prosthetic body to be an artificial big toe.In 2011, scientists pointed out that Egyptians with fake toes could walk with sandals more easily than those who lost their toes without replacement parts.(Photo: PNAS)

Most adults have 24 ribs (12 pairs).However, one out of every 500 people contains an extra rib, called the neck rib.It grows from the lower part of the neck, just above the collarbone.This side ribs can cause health problems if inserted into adjacent blood vessels or nerves.(Photo: AAAS)

People do not directly control bones.When we move our arms, legs or any other part of the body, we are ordering muscles to attach to the moving bone.(Photos: School of Medicine and BioDigital Systems)
