SUPERFICIAL BODY MUSCLES. 



The sterno-facialis is a thin sheet of muscular fibers arising from fasciae 

 along the anterior jiart of the pectoralis. The fibers from opposite sides are 

 somewhat interlaced on the throat. This sheet extends forward over the 

 prominent thyroid glands to the mandibular symphysis and dorsally on to the 

 sides of the face, becoming inserted by thin tendinous fibers into the skin of this 



The panniculus camosiis is extraordinarily developed and thickened over the 

 dorsal region, where it forms a tough, mainly tendinous .sheet about 2 mm. thick. 

 This sheet is attached to the tips of the dorsal spines by thin strands of muscle 

 and tendon and to the vertebral edge of each scapula and the posterior third of 

 the sca])ular ci-est. A few slight strands of tissue connect it with the ecto- and 

 ento-pectorales ventrally, and its main insertion, after dipping beneath the ecto- 

 pectoralis, is upon the antero-internal side of the humerus about a centimeter 

 distal to the head. This insertion is tendinous and some 6 mm. long. Antero- 

 dorsally this great investing sheet is more or less continuous with the thin mus- 

 cular and tendinous sheet of trapezius muscles that covers the top of the head 

 and neck and inserts along the anterior length of the scapular spine. Posteriorly 

 the panniculus merges into a thin sheet investing the thigh as far as the knee 

 and backward around the base of the tail. It is everywhere closely connected 

 to the skin.
