 muscles of the left shoulder and neck. 



Preparation. — After the reflection of the skin and dermal mus- 

 cles as in Fig. 66. the following muscles were transected and re-

Bones. — Acromion (§ 393). — This process of the mesoscapula is seen to afford origin to 

 the acromio-dcltoideus. 



Clavicida (§§ 422, 608). — By the reflection of the clavo-trrtpezius and the deflection of 

 the clavo-mastoideus, the clavicle is brought into view. Its name is connected with its 

 sternal end.
