The HUMERUS is found between the scapula and the radius/ulna.
Important features of the humerus:
1-GREATER TUBERCLE: a roughened PALPABLE area on the proximal, craniolateral aspect of the bone
2-HEAD: a smooth, rounded proximocaudal protuberance. It articulates with the glenoid cavity of the scapula forming the SHOULDER JOINT
3-DELTOID TUBEROSITY: a palpable ridge on the craniolateral aspect of the proximal 1/3rd of the bone
4-LATERAL EPICONDYLE: a distolateral PALPABLE prominence
5-LESSER TUBERCLE: a prominence on the proximal, medial aspect of the bone
6-MEDIAL EPICONDYLE: a distomedial PALPABLE prominence
7-TROCHLEA: a circular concavity medial to a ridge in the craniodistal part of the bone. Articulates with the radius and ulna forming part of the ELBOW JOINT
8-CAPITULUM: a circular concavity LATERAL to a ridge in the craniodistal part of the bone. Articulates with the radius forming part of the ELBOW JOINT
9-RADIAL FOSSA: a craniodistal concavity in the humeral condyle
10-SUPRATROCHLEAR FORAMEN: an opening between the radial fossa and olecranon fossa
11-CONDYLE: the distal part of the humerus including the articulating areas, the epicondyles, and fossae and supratrochlear foramen
12-OLECRANON FOSSA: a caudodistal concavity in the humeral condyle
