15 arrange the bones of the upper extremity, starting from the shoulder joint and going outwards. humerus carpal bone phalange radius clavicle metacarpal bone

Explanation:

The clavicle is an even bone present in the human skeleton that connects the upper limbs to the trunk. It is palpable throughout, and is classified as long bone but without medullary cavity consisting of cancellous bone with compact bone lining.

After the clavicle lies the humerus, which is larger than the bones of the arm. Located between the shoulder and elbow, it is categorized as a long bone because its length exceeds its width and thickness. Here is your complete anatomy, joints, and the muscles that surround it.

Next is the radius which is the lateral bone of the forearm. It is the shortest of the two bones of the forearm. It articulates proximally with the humerus and ulna and distally with the carpal bones and ulna. It has two epiphyses and one diaphysis.

The carpal bones, in turn, are arranged in two parallel rows: the proximal (connected to the arm) and the distal (connected to the metacarpals). They are followed by the metacarpal bones that represent the skeleton of the palm. It is made up of five equal elongated bones that articulate with the carpal bones and the phalanges.

The phalanges, in turn, correspond to the bones of the thumb, index, middle, ring and auricular fingers. In total we have 18 phalanges. The phalanges articulate with the bones of the metacarpal. Each finger has three phalanges. The thumb has only two phalanges.
