How Your Forearm Bones Look When you Twist Your Arm #anatomy The radius and ulna are the two bones in the forearm that contribute to the rotation of the forearm, a movement known as pronation. The radius is located on the thumb side of the forearm, while the ulna is on the pinky side. During pronation, the head of the radius rotates around the ulna, resulting in the palm of the hand facing downwards or towards the back. This rotational movement allows for various functional activities such as turning a doorknob, using a screwdriver, or performing tasks that involve grasping and twisting. The radius and ulna work together in a joint called the proximal radioulnar joint, which is located near the elbow. Ligaments and muscles surrounding this joint help stabilize and control the rotational movement during pronation. Understanding the role of the radius and ulna in pronation is important for maintaining proper forearm function and preventing injuries. Any issues with these bones or the supporting structures can affect the smooth rotation of the forearm, leading to limited mobility or discomfort. #RadiusAndUlna #ForearmPronation #RotationFunction #ProximalRadioulnarJoint #ForearmMobility #HandFunction #FunctionalActivities #ForearmRotation #ForearmAnatomy #JointFlexibility #ForearmStability #MuscleCoordination #JointHealth #PronationMovement #ForearmFunction #HandRotation #JointSupport #InjuryPrevention #ForearmCare #BoneHealth #doctor #medicineexplained #fyp #interesting #interestingfacts #interestingvideos #interestingthings
