Radius And Ulna Anatomical Position
What Is the Office of the Ulna?
Similar many other bones, the ulna stores minerals and produces blood cells in the os marrow. Withal, the primary purpose of the ulna is to support the forearm and allow it to motion, according to LearnBones.com. The ulna extends from the elbow to the bones of the wrist and works in conjunction with another long bone in the forearm, chosen the radius.
According to Healthline, the ulna is virtually 50 percent larger in diameter than the radius is at four to five months of age. However, over the course of growing and developing, the radius overtakes the ulna in size. By adulthood, the ulna is only virtually half as thick equally the radius. Healthline contends that when the ulna breaks, it usually does so well-nigh the wrist or where the ulna and radius fuse to class a stationary joint.
InnerBody.com explains that the ulna is located on the inside of the arm, when the palms are held upwards. In other words, it is on the side of the arm that holds the pinky, while the radius is on the side that holds the thumb.
LearnBones.com states that the ulna is slightly curved, as are the other bones in the arm. Many different muscles and tendons adhere to the ulna to allow movement in the arm, wrist and hand.
