Note on SupraclaviculaT Muscles. 14:9 



omohyoid attached to the sternohyoid or sternothyroid at the inner 

 (anterior) end. The Separation of the sternohyoid up to the point of 

 attachment of the omohyoid may produce a sternoscapular muscle, 

 or secondly a costoscapular muscle. 



The evidence seems to be in favour of the view that supra- 

 clavicular muscles of the kind I have mentioned belong all to the 

 same primitive muscle layer, viz. the internal oblique layer of 

 Humphry, and that the other bands fibrous or muscular may occupy 

 positions superficial to the other muscle. 



The supraclavicular fibrous band to wliich the sternocleido- 

 mastoid and trapezius are attached, belong clearly to the external 

 oblique layer of Humphry, whilst the transverse bands met with 

 superficial to the clavicle, and these muscles belong to the panniculus 

 carnosus.
