Neck area Posterior

The posterior neck region (lat. regio cervicalis posterior, pna: regio colli posterior, bna; regio colli dorsalis, jna; synonym nuchal region) is one of the anatomical regions of the neck.

Located on the back of the neck. It is bounded anteriorly by the posterior edge of the sternocleidomastoid muscle, and laterally by the posterior edges of the sternocleidomastoid and trapezius muscles.

In the posterior neck area the following anatomical structures are located:

1. Neck muscles (trapezius, semispinalis, semipennate and small muscles)

2. Lymph nodes of the neck (posterior deep and superficial)

3. Nerve plexuses of the neck (posterior branches of the cervical plexus)

4. Blood vessels of the neck (posterior branches of the external carotid artery and internal jugular vein)

The posterior neck region plays an important role in the movement and sensation of the head and neck.

Neck Region - Posterior The region at the back of the neck region is made up of muscles, tendons and blood vessels that help stabilize the neck and head. The functioning of this area is very important for maintaining health, since its activity can affect not only the muscles of the neck and head, but also the overall health of the body.

Muscles of the Back of the Neck This is where the massive muscle groups in the neck work, including the trapezius, inferior hyoid, and trapezius muscles. This muscle group is responsible for supporting the head and neck in an upright position. The trapezius muscle also rotates the neck, and the inferior hyoid muscle helps move the head laterally.

Blood Vessels and Nerves of the Posterior Neck The region also contains many blood vessels
