Dorsal region of neck

Regio colli dorsalis

Definition

Juliette Garnodier

The dorsal region of the neck extends from the base of the skull (occipital region) to the withers, at the level of the first thoracic vertebrae.

It is characterized by the spinous processes of the cervical vertebrae, the nuchal ligament (particularly well developed in large herbivores), and a substantial muscle mass (splenius, rhomboideus, trapezius). This region is essential for supporting the head and allows extension, lateral flexion, and rotational movements of the neck.
