Which is the longest bone in human body?

Which is the longest bone in human body?

  • (A) Femur
  • (B) Sternum
  • (C) Malleus
  • (D) Spine
  • Femur: Starting at the hip, then reaching down to the knee, the femur holds title as the body’s longest bone. This sturdy part also happens to be the heaviest single bone inside us. Strength matters here, given it supports much of our weight. Roughly twenty-five percent of someone’s full height comes just from this one piece alone.
  • Sternum: A bony plate up front in your torso goes by another name too - people call it the breastbone. Right down the middle of the chest, this piece lies flat and wide. Though sizable among its kind, it doesn’t come close to matching the thigh bone’s span.
  • Malleus: A little bone called the malleus sits deep inside your ear. Not even close to big - just a few millimeters long - it plays a quiet role among its two neighbors. Part of a trio known as ossicles, it moves sound along without drawing attention. Tiny but necessary, it connects pieces others might overlook.
  • Spine: Starting off, the spine isn’t just one solid piece of bone. Instead, it’s made up of around thirty-three separate parts known as vertebrae. These small bones stack together to form what we call the backbone. Each segment plays its own role in support and movement. Far from being rigid, this structure allows flexibility through linked pieces. You might think it's stiff, yet it bends thanks to multiple components working in sequence.
