riYOLOQY. 



Subcutaneous Region. 

 Panniculus Carnosus. 



The facial portion consists of scattered bundles of fibres, best 

 developed over the masseter muscles, being continued into 

 the submaxillary space and over the parotid gland. Other 

 fibres reach the angle of the mouth, which they retract. 



The cervical portion is attached below, to the cariniform cartil- 

 age of the sternum. Here it is a thick band, but becomes 

 thin anteriorly and superiorly! 



The thoracic portion consists of fibres running in a vertical dir- 

 ection, covering the scapular region. 



The abdominal portion reaches from the groin to the elbow 

 muscles, where it sends a tendon to be attached to the 

 inner tuberosity of the humerus. 



The action of this muscle is to shake the skin, thus removing 

 ofiending insects.
