The actual number of joints in your limbs doesn’t vary except in cases of very severe developmental abnormality. But the ligaments that hold together the bones on either side of a joint do vary in elasticity from one person to another. The young, and those that regularly stretch these joints through gymnastics or yoga, can achieve a range of movement that appears unnatural to the rest of us.Truly freakish joint positioning, known as hypermobility is either due to misaligned or malformed bones at the joints or Ehlers-Danlos Syndrome which is an inherited condition that affects the structure of the collagen protein in the skin, ligaments and bones. There are also some people that have reduced joint proprioception, so the brain misjudges how stretched a joint is and does not signal the muscles appropriately.
