Bones of the Upper Limbs
The bones of the upper limbs connect it to the axial skeleton.
The clavicle or collarbone as it is more commonly known, extends between the manubrium of the sternum and the acromion of the scapula.
The scapula or shoulder blade as it is more commonly known, is the bone that joins the upper limbs and the trunk. It also serves as the attachment point for 17 muscles.
The humerus is also the longest bone in the upper limbs. It runs from the shoulder to the elbow and both ends of the humerus form joints - glenohumeral joint and elbow joint. 13 muscles attach to the humerus to allow for movements of the hand and elbow.
The ulna is one of the two long bones in the forearm and 13 muscles attach here.
The radius is one of the other two long bones in the forearm. 9 muscles attach here (confirm this fact).
The carpals, metacarpals and phalanges together, make up the bones of the hands. They provide support and flexibility to the soft tissues in this region.
