The neck is a vital anatomical region that connects the head to the torso. It contains key structures including blood vessels, nerves, lymphatics, muscles, and airways.
Clinically and anatomically, the neck is divided into two major surface regions: the anterior triangle and the posterior triangle. These triangles are defined by easily identifiable surface landmarks and are commonly used as reference points in clinical examination, surgery, and radiology.
Each triangle of the neck contains important anatomical structures and is further divided into smaller subdivisions. Understanding the areas of the neck helps clinicians localise pathology, navigate surgical approaches, and interpret imaging more effectively.
In this section, you’ll learn about the anatomical boundaries, contents, and clinical relevance of the anterior and posterior triangles of the neck, supported by clear illustrations and 3D models.
