1. Rhomboideus. (Figs. 101, 6; 104, 1, 2.) 



Synonyms. Described by Bourgelat as two muscles, the //;->;/ ih-rntor "f //< 

 ehoulder and the rhomltoitJeus, these were termed by Girard the oerrioo-iahntpalarUl 

 and dorso-subscapnlaris. (This is the rhomboideus limyus and brevis of IVrcivall, and 

 the dorto-gcapvlaris and cervico-nibscapularis of Leyh.) 



Form Situation Direction. This muscle has the form of a very 

 elongated triangle, and is situated at the inner aspect of the cervical

 direction it follows.

Structure Attachments. It is composed of thick, fleshy fasciculi, tho 

 anterior of which arc oblique downwards and backwards, tho posterior 

 passing directly downwards. These fasciculi are fixed by their superior 

 extremity to the funicular portion of the cervical ligament and tin; summits 

 of the spinous processes of the four or five dorsal vertebra) succeeding the
