The scapula, or shoulder blade, is not connected with 

 the back bone, but lies imbedded in the muscles of the 

 shoulder. This loose attachment aids materially in giving 

 freedom of motion to the arm. The scapula really consists 

 of two bones, the scapula proper and the coracoid bone, 

 which latter, however, has been reduced to a mere process, 

 which has grown on to the scapula, and which is called the 

 coracoid process. In birds this coracoid process is a very 

 large and distinct bone, and serves to support the wings,
