1 The head is directed medially, backwards and
upwards. It articulates with the glenoid cavity of the
scapula to form the shoulder joint. The head forms
about one-third of a sphere and is much larger than
the glenoid cavity.
2 The line separating the head from the rest of the
upper end is called t}:re anatomical neck.
3 The lesser tubercle (Latin lump) is an elevation on the

4 The greater tubercle is an elevation that forms the
