What is the scientific name for radius bone?
The Main Bone of the Forearm, Also Known as the Radial Bone The radius and ulna pivot around one another to allow rotation of the wrist. Together, along with the humerus, they create the elbow joint.
What is the radius bone in the arm?
The radius (shown in red) is a bone in the forearm. The radius is part of two joints: the elbow and the wrist. At the elbow, it joins with the capitulum of the humerus, and in a separate region, with the ulna at the radial notch. At the wrist, the radius forms a joint with the ulna bone.
What is humerus and radius?
The humerus is the single bone of the upper arm, and the ulna (medially) and the radius (laterally) are the paired bones of the forearm. The base of the hand contains eight bones, each called a carpal bone, and the palm of the hand is formed by five bones, each called a metacarpal bone.
What are the names of the arm bones?
The elbow is where the two bones of the forearm – the radius on the thumb side of the arm and the ulna on the pinky finger side – meet the bone of the upper arm — the humerus. The lower end of the humerus flares out into two rounded protrusions called epicondyles, where muscles attach.
What is ulna and radius?
The radius and ulna are long bones that make up the forearm, extending from the elbow to the wrist. In the anatomical position, the radius is found in the lateral forearm, while the ulna is found in the medial forearm.
What is arm medical term?
Arm: 1. In popular usage, the appendage that extends from the shoulder to the hand. However, the medical definition refers to the upper extremity extending from the shoulder only to the elbow, excluding the forearm, which extends from the elbow to the wrist. The arm contains one bone: the humerus.
What is the common name for ulna and radius?
Skeletal System Common Names for Bones

| Ilium | Hip bone |
What is the name of the distal part of the radius?
Distal Region of the Radius In the medial surface, there is a concavity, called the ulnar notch, which articulates with the head of ulna, forming the distal radioulnar joint.
What joint is the radius and ulna?
The radioulnar joints are two joints between the two bones of the forearm: the ulna, on the medial side, and the radius, on the lateral side. There’s one superior, or proximal radioulnar joint, and one inferior, or distal radioulnar joint, and together they allow for the movements of pronation and supination.
What is the upper half of the arm called?
Your arm is made up of three bones: the upper arm bone (humerus) and two forearm bones (the ulna and the radius).
What is the area just above the elbow called?
lateral epicondyle
The outside (lateral) bump just above the elbow is called the lateral epicondyle. Most of the muscles that straighten the fingers and wrist come together and attach to the medial epicondyle, or the bump on the inside of your arm just above the elbow.
What is the radius anatomy?
The radius is one of the two bones that make up the forearm, the other being the ulna. It forms the radio-carpel joint at the wrist and the radio-ulnar joint at the elbow. It is in the lateral forearm when in the anatomical position. It is the smaller of the two bones.
