Areas of the Neck

Overview

The neck is divided into major triangular regions that provide a clear framework for understanding the organisation of its neurovascular and visceral structures. This section introduces the anterior and posterior triangles, which together form the basis for anatomical description, surface anatomy and surgical approaches in the cervical region.

Key Structures

Topics include the anterior triangle of the neck, with its subdivisions and important neurovascular and visceral contents, and the posterior triangle, which contains key muscular, vascular and neural structures. Each article outlines boundaries, subdivisions and anatomical relationships.

Clinical Relevance and Learning Focus

Knowledge of the cervical triangles is vital for interpreting surface landmarks, assessing trauma, evaluating lymphadenopathy and planning surgical access. These regions provide a practical framework for clinical examination and for understanding pathways of infection, referred pain and neurovascular compromise.
