 the shoulder joint. In the dissection of the lateral aspect of the 

 shoulder it will be found under the deltoid muscle. 



o. A. circumflexa scapulce.— The circumflex artery of the scapula

 of the posterior circumflex. A branch is given to the subscapular

muscle, after which the artery pierces the origin of the long head 



of the triceps and bends round the axillary border of the scapula 



to enter the infraspinous fossa. Eami supply the infraspinous, teres 



minor, and supraspinous muscles, and terminal twigs reach the skin 



in the acromial region. The nutrient artery of the scapula is furnished 



by the circumflex scapular. 



4. A number of inconstant muscular branches (rami musculares) 



are supplied to the subscapular, teres major, and triceps muscles.
