Answer

Femur

Explanation

The femur, also known as the thigh bone, is the longest, largest, and strongest bone in the human body. It extends from the hip joint down to the knee joint. Because it forms the core of the thigh, it is incredibly dense and strong, capable of supporting the entire weight of the human body. Conversely, the smallest bone in the human body is the 'stapes', located in the middle ear.

Key Points

  • > The femur bone accounts for roughly one-quarter (25%) of a person's overall height.
  • > The stapes, located in the middle ear, is the smallest and lightest bone in the human skeleton.
  • > The humerus is the long bone in the upper arm, running from the shoulder to the elbow.
  • > The tibia and fibula are the two bones found in the lower leg (below the knee).
  • > An adult human has 206 bones, whereas an infant is born with around 300 bones that eventually fuse.
