Dissection of anterior and lateral regions of neck
Infrahyoid muscles; internal jugular vein; prevertebral fascia, left lateral view
The sternocleidomastoid and trapezius muscles have been removed. The inferior part of the middle layer of cervical fascia has been preserved and its continuity with the prevertebral fascia shown.
