Dissection of anterior and lateral regions of neck Contents of left posterior cervical triangle; superficial cervical lymphatics, lateral view The external layer of cervical fascia has been removed from the left side of the neck except from the lower part of the posterior triangle. In this region the lamina of this fascia which passes deep to the sternocleidomastoid and trapezius muscles remains in place. This layer has openings for lymphatic vessels (20) and veins, but can be traced superiorly to the midpart of the view where it becomes continuous with the prevertibral fascia (13). The left shoulder occupies the midforeground of the view. 1 . Upper pointer: Parotid gland Lower pointer: Parotid-masseteric fascia 2 . Cervical branch of facial nerve 3 .
