This podcast outlines the neck triangles and their boundaries, the different neck fasciae (investing layer of deep cervical, pretracheal, prevertebral, carotid sheath, buccopharyngeal and pharyngobasilar) and their significance in surgery and sepsis. There is a preamble about how to approach the detailed anatomy of the head and neck by compartmentalized study. The subdivisions of the triangles are outlined with supportive images on the Facebook site Anatopod.
