The fascia colli on the right side after the removal of the platysma. The superficial lamina is 

 partly taken away in places where it is sharply separated from the deep lamina. The middle portion 

 of the sternocleidomastoid muscle has been removed to show the deep layer of the fascia colli, under 

 which is seen the upper belly of the omohyoid muscle shining through. (After Toldt, Anat. Atlas,
