- The humerus is the bone of the (upper) arm.
- The humerus articulates with:
- the scapula proximally, forming the shoulder (glenohumeral) joint.
- the ulna distally, forming the elbow (humeroulnar) joint.
- the radius distally, forming the elbow (humeroradial) joint.
NOTES:
- The greater tubercle is located laterally and the lesser tubercle is located medially.
- The bicipital groove of the humerus runs between the greater and lesser tubercles. The proximal tendon of the long head of the biceps brachii runs through this groove.
