TOPOGRAPHICAL ANATOMY OF THE 



M. TRAPEZIUS (;ervicalis. — The cervical part of the trapezius ^ 

 muscle forms a thin, pale, triangular sheet with au origin from the 

 ligamentum nuchfe, extending from the third thoracic vertebra to the 

 level of the epistropheus. Its insertion is partly to the spine of the

scapula and partly to the scapular fascia. To clean the surface of the 

 trapezius is a tedious task because of the firm adhesion of the cervical 

 fascia, the fibres of which run at right angles to the direction of the 

 fibres of the muscle. 



The ventral border of the trapezius is adherent to and may slightly 

 overlap the border of the brachio-cephalic muscle.
