What is an ulna bone?

The ulna is the longest, thinnest bone of the forearm. It articulates proximally with the trochlea of the humerus and with the head of the radius. Distally it articulates with the ulnar notch of the radius and with an articular disk that separates it from the carpal bones.

Why is it called clavicle?

It receives its name from the Latin clavicula (“little key”), because the bone rotates along its axis like a key when the shoulder is abducted. The clavicle is the most commonly fractured bone. It can easily be fractured by impacts to the shoulder from the force of falling on outstretched arms or by a direct hit.

Why is collarbone called beauty bone?

Synonyms: Radial bone. 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 a metatarsal bone?

The metatarsal bones are the long bones in your foot that connect your ankle to your toes. They also help you balance when you stand and walk. A sudden blow or severe twist of your foot, or overuse, can cause a break, or acute (sudden) fracture, in one of the bones.

The shoulder is made up of three bones: the scapula (shoulder blade), clavicle (collarbone) and humerus (upper arm bone). Two joints in the shoulder allow it to move: the acromioclavicular joint, where the highest point of the scapula (acromion) meets the clavicle, and the glenohumeral joint.
