omohyoid. Its anterior fibres are inserted near the lower edge, its 

 posterior ones gradually ascend towards the upper edge of the bone. 



Rectus capitis anticus major. — Eises by tendon from the basi- 

 occipital process: also from the hinder edge of the lower surface of 

 the bone ; — inserted into the upper part of the under surface of the 

 third and fourth ribs, and sides of the bodies of the posterior 

 cervical vertebrae. 



Longus colli. — From the ventral surfaces of the atlas and axis 

 and posterior cervical vertebrae ; inserted into the summit of the 

 first and second ribs, and thence continued to be inserted with the 

 rectus anticus. 



Scalenus. — Unusually small ; rising from the transverse process 

 of the fifth cervical vetebra it is inserted into the fore edge of the 

 first (cervical) rib. 



Cervicalis ascendens. — An indefinable continuation of the sacro- 

 lumbalis. It may be said to be inserted into the three anterior 

 ribs, the three posterior cervical vetebrse and rather strongly into 

 the deep surface of the levator scapulae near its origin. 



Muscles of the shoulder — girdle and fore limb. 



Pectoralis major (fig. 3 — p. m.), — From the last sternal rib, and 

 the middle line of the sternum to the base of the clavicle, but not 

 from the interclavicle ; inserted into the summit of the radial 

 tuberosity of the humerus. 



Pectoralis minor. — Nob represented. 



Trapezius. — Rises by a thin, strong aponeurosis from the eighth 

 rib; anteriorly its aponeurosis becomes continuous with the nuchal 

 fascia. Inserted by a broad tendon into the outer side of the edge 

 of the anterior angle of the scapula. 



Deltoid (fig. 3 — cl). — In two divisions. The first from the 

 base of the suprascapula and summit of the scapula, and from the 

 ligamentous sepiment between it and the latissimus dorsi over the 

 subscapularis. The second from the whole posterior edge of the 

 clavicle. The common insertion is into the outer side of the 

 summit of the radial tuberosity of the humerus.
