The neck region is anatomically divided into an anterior triangle and a posterolateral triangle. This lab will focus on the posterolateral triangle. Initially, the skin covering both regions of the neck will be reflected, and then the boundaries of the posterolateral triangle will be identified. The fascial roof of the posterolateral triangle will be removed to study the structures found within the triangle. Finally, the fascial floor of the triangle will be removed and the muscles which lie deep to it will be examined. Due to the density of the fascial layers, dissection is often tedious and slow.

Persistence and patience are necessary for a successful dissection of this region.
