IX. THE MUSCULATURE OF THE TRUNK. 



A PECTOKAL and a pelvic limb may now be removed 

 from tlie same, say the left, side, and tlie opposite limbs 

 are allowed to remain, in order that we may compare 

 the relations existing 1;)etween their mnscles and the 

 muscles of the trunk, which are to be descrilied in the 

 present section. Next, we carefully remove the entire 

 remaining integuments from the cadaver of our specimen, 

 cutting the dermal muscles as w^e do so, close to their 

 origins. In preparing the neck for our investigations, we 

 should carefully remove the trachea ; all superfluous fat 

 and connective tissue ; and the vessels and oesophagus. 

 At its cephalic extremity, we clear away the entire 

 hyoidean apparatus, and with it any other structures 

 that may stand in the way of our complete view of the 

 method of attachment of the neck-muscles to the base 

 of the cranium. 



In speaking of the muscles of the vertebrae. Sir 

 Richard Owen says that " the muscles of the cervical 

 region are the most developed, as might be expected 

 from the size and mobility of this j^art of the spine ; 

 the muscles which are situated on the dorsal and 

 lumbar regions are, on the other hand, very indistinct, 

 feeble, and but slightly carneous ; they are not, however,
