are your arms as long as your height
Arm span Arm span or reach (sometimes referred to as wingspan) is the physical measurement of the length from one end of an individual's arms (measured at the fingertips) to the other when raised parallel to the ground at shoulder height at a 90Â° angle. The average reach correlates to the person's height. Age and sex have to be taken into account to best predict height from arm span.[1]
Ulna The ulna is a long bone found in the forearm that stretches from the elbow to the smallest finger, and when in anatomical position, is found on the medial side of the forearm. It runs parallel to the radius, the other long bone in the forearm, and is the larger and longer of the two.
