Understanding Shoulder Anatomy

Discover how your shoulder works

The shoulder joint has the largest range of motion out of all the joints in the body. This flexibility allows you to hit a backhand swing in tennis or stretch to reach something on a top shelf. The shoulder also helps you position your hands for movements such as waving goodbye or using the mouse on your computer.

The shoulder consists of 3 bones:

  • shoulder blade (scapula)
  • collar bone (clavicle)
  • upper arm bone (humerus)
