This section is going to take a look at some of the most interesting facts about the bones of the human body. Understanding the inner workings of the human body is both fascinating and rewarding; while taking the time to know what you're actually composed of is equally as illuminative.

Interesting Facts about the Human Body

  • Did you know we're actually born with approximately 270 bones, and as we age, many of these bones fuse to ultimately arriving at the typical figure of 206, usually by the age of ~30. However, we must take this figure with caution. For instance, some types of the same bone are counted i.e. Pisiform sesamoid, while the Hallux sesamoid's are not counted. These peculiarities also extend the cranium ,which are counted as a multitude of separate bones within a unified cranium. Despite these minor discrepancies, the figure is most approximated and accepted at 206.
  • The word Skeleton comes from the Greek skeletos meaning "dried body" or "mummy".
  • The human skeleton is often split into the Axial Skeleton (80 bones) and the Appendicular Skeleton (126 bones) ~ the Axial Skeleton comprises the vertebral column, the rib cage, and the skull whereas the Appendicular Skeleton is composed of the attaching limbs such as pectoral and pelvic girdles, arms, legs etc. 
  • Some of the more interesting facts about the human body lie in the function of the skeleton itself; which is much more diverse than you probably thought:

- Support: The structure of the skeleton is what maintains its shape. The shape of the skeleton allows the muscles to coordinate their functions.

- Protection: For example, the skull protects the brain while the vertebrae protect the spinal cord.

- Movement: The shape of the skeleton permits flexibility of the different types of joints, hence aiding your overall movement.

- Blood Cell Production: Bone marrow is one of the principle sites of blood cell production; a process known as Hematopoeisis.

- Endocrine Regulation: Osteocalcin is a hormone released by bone cells that has the effect of influencing the level of glucose and fat deposits in the body by increasing the release of insulin. 

- Storage: For example, the bone matrix can store calcium while the bone marrow can store iron.

  • What is the smallest bone in the human body? Stirrup Bone (Stapes); it's found in the Middle Ear!
  • What is the largest bone in the human body? The Femur (Thighbone)
  • The Hyoid (see below) is the only bone not connected to any other bone in the body.
  • Ossification is the name by which bone is created in the body. When bone becomes solid, the bone is said to ossify. 
  • The Xiphoid Process is the name of the lower part of the Sternum. 
  • The upper most vertebrae is called the Atlas Bone .
  • The ends of a bone are called its Epiphysis while the part in between the ends is called the Diaphysis. See here .
  • The Olecranon is that part of the end of an elbow, a part of the body that's quite susceptible to inflammation!
