Question
Answer
Clavicle  Collar bone  
Sternal end of the clavicle  Medial end of the collar bone  
Acromial end of the clavicle  Lateral end of the collar bone  
Scapula  Shoulder blade  
Medial border of the scapula  Border of the scapula nearest the vertebrae  
Lateral border of the scapula  Lateral, inferior border of the scapula  
Spine of the scapula  Divides the lateral surface into the anterior supraspinous fossa and the posterior infraspinous fossa  
Acromion process  Finger-like extension of the spine that points ventrally  
Coracoid process  Small beak like projection of the scapula that points forward  
Supraspinous fossa  Surface of the scapula above the spine of the scapula  
Infraspinous fossa  Surface of the scapula below the spine of the scapula  
Subscapular fossa  Covers most of the anterior surface of the scapula  
Glenoid fossa  Hollow in the head of the scapula that receives the head of the humerus to make the shoulder joint  
Humerus  Upper arm bone  
Greater tubercle of the humerus  Forms the most prominent bony point of the shoulder  
Lesser tubercle of the humerus  Medial to the greater and separated from it by the intertubercular groove  
Bicipital groove  Groove between the greater and lesser tubercles  
Deltoid tuberosity  A rough elevation about the middle of the lateral side of the shaft of the humerus, giving attachment to the deltoid muscle  
Medial epicondyle of the humerus  Most medial prominent bone of the elbow  
Lateral epicondyle of the humerus  Most lateral bone of the elbow  
Trochlea of the humerus  Place between the epicondyles that the ulna articulates with  
Capitulum of the humerus  Lateral part of the articular surface of the distal end of the humerus  
Radius  Lateral and slightly shorter of the two bones of the human forearm  
Inferior angle of the scapula  Bottom angle of the scapula  
Superior angle of the scapula  Top angle of the scapula  
Head of the humerus  Hemisphere shaped area on the humerus that articulates with the glenoid fossa of the scapula  
Anatomical neck of the humerus  constriction of the humerus immediately adjoining the margin of the head, just below its proximal articular surface  
Coronoid fossa  Cavity in the anterior aspect of the distal humerus proximal to the trochlea of humerus  
Olecranon fossa  Deep hollow on the posterior surface of the distal humerus proximal to the trochlea of humerus  
Head of the radius  Disk-shaped upper extremity articulating with the capitulum of the humerus  
Radial tuberosity  Eminence on the anterior inner surface of the radius just distal to the radial neck  
Styloid process of the radius  Blunt projection from the lateral surface of the distal end of the radius  
Ulna  Medial and larger of the 2 bones of the forearm  
Ulnar tuberosity  Tuberosity just distal to the coronoid process  
Olecranon process  Process at the proximal end of the ulna which projects behind the articulation with the humerus and forms the bony prominence of the elbow  
Coronoid process of the ulna  Anterior eminence of the proximal ulna, distal to the olecranon  
Styloid process of the ulna  Medial non-articular process on the distal end of the ulna  
Radial notch  Narrow depression on the lateral side of the coronoid process of the ulna that articulates with the head of the radius  
Neck of the radius  Narrow part of the shaft just below the head  
Carpal  Any of the eight small bones of the wrist  
Metacarpus  That part of the hand between the carpus and phalanges  
Scaphoid bone  Found on the thumb side of the hand, within the anotomical snuffbox. It is approximately the size and shape of a cashew  
Lunate bone  Second of three bones forming the proximal row of bones in the wrist  
Triquetral bone  Bone in the proximal row of carpal bones lying between the lunate and pisiform bones  
Pisiform bone  Small knobbly, pea-shaped bone that articulates only with the triquetral bone  
Trapezium bone  Most lateral bone of the distal row of carpal bones  
Trapezoid bone  Bone in the distal row of carpal bones lying between the trapezium and capitate bones  
Capitate bone  Bone in the distal row of carpal bones lying between the trapezoid and hamate bones  
Hamate bone  Medial bone in the distal row of carpal bones  
Phalanges of the hand  Bones that form fingers and are named after the digit and their distance from the body  
Proximal phalanges of the hand  Closest to the hand and articulate with the metacarpals  
Middle phalanges of the hand  Between the distal and proximal phalanges. The thumb does not have one  
Distal phalanges of the hand  Form the tips of the fingers  
How many phalanges are there per hand?  14
