The Neck

Overview

The neck forms a vital connection between the head and thorax, housing essential neurovascular, respiratory and digestive structures. This section explores the layered organisation of the cervical region and the complex interplay of muscles, vessels and fascia that define it.

Key Structures

Articles cover the cervical vertebrae and muscles, fascial planes, major blood vessels, lymphatics and cranial nerves passing through the neck. The thyroid and parathyroid glands, larynx and pharynx are described in depth, with illustrations that clarify three-dimensional relationships for clinical application.

Clinical Relevance and Learning Focus

A detailed understanding of neck anatomy underpins safe airway management, surgical procedures and neurological examination. The content connects structure to function, supporting learners in interpreting cross-sectional imaging and identifying clinical landmarks with confidence.
