184 MYOLOGY. 



the aponeurosis of the panniculus, and infero-laterally becomes 

 blended with that muscle ; hence it may be said to have an 

 indirect sternal attachment. 



Action. When the head is fixed, it advances the entire limb ; 

 if the limbs are fixed, it aids in turning the head and neck to 

 one side, or with its fellow in depressing them. 



TKAPEZIUS CERVICALIS. 

 (Cervico-acromialis. ) 



(PL. II. 13.) 



Situated supero-posteriorly, this, the cervical portion of the 

 trapezius muscle, is thin, flat, and triangular, its fibres converging 

 downwards and backwards. It is aponeurotic above, and poste- 

 riorly, where it joins the dorsal portion. 



Origin. From the funicular portion of the ligamentum nuchse. 



Insertion. With the dorsal trapezius to the spine of the 

 scapula, at its tubercle, and to the scapula fascia. 



Relation. Externally with fascia from the levator humeri and 

 panniculus ; internally with the splenius, serratus magnus, rhom- 

 boideus longus, pectoralis parvus, and antea spinatus. 



Action. It elevates and draws the shoulder forwards. 



RHOMBOIDEUS LONGUS. 

 ( Cer vico-sub scapular is. ) 



(PL. III. 9.) 



It is placed on the supero-lateral part of the neck, just below 

 the cordiform portion of the ligamentum nuchae. It appears as 

 a tapering triangle, widest posteriorly, and very fleshy in its 

 structure. 



Origin. From the funicular portion of the ligamentum nuchas, 

 as high as the second cervical vertebra. 



Insertion. To the inner surface of the anterior angle of the 

 scapula, and to its cartilage of prolongation, just above the 

 serratus magnus. 



Relation. Externally with the cervical trapezius ; inferiorly 

 with the splenius ; posteriorly with the rhomboideus brevis, with 

 which it blends ; internally with the ligamentum nuchse. 



Action. To elevate and draw the scapula forwards.
