Head And Neck Anatomy Posterior Triangle Of The Neck

The posterior triangle or lateral cervical region is a region of the neck.

Anatomy of the posterior neck. The posterior triangle of the neck contains many muscles which make up the borders and the floor of the area. The nodes along the accessory are the first echelon for the nasopharynx and second echelon for the areas drained by the anterior. The roof is formed by fascia and the floor is formed by the splenius capitus levator scapulae and scalene muscles.

The splenius capitis originates on the spinous processes of the vertebra the spinous processes of c7 to t4 and it inserts onto the back of the skull on the mastoid process and just below the superior nuchal line on the occipital bone. Muscles of the neck posterior triangle prevertebral and lateral muscles. Those that are found along the accessory nerve and those related to the thyrocervical vessels.

The posterior border of sternocleidomastoid and the anterior border of trapezius form the anterior and posterior borders of the posterior triangle of the neck respectively. The clinical aspect of the anatomy contained in the posterior neck triangle is useful for a wide variety of medical specialties including anesthesiology otolaryngology physical medicine and rehabilitation and others. Explore and learn about the muscles within the posterior triangle fo the neck with our 3d interactive anatomy atlas.

The neck also contains the thyroid and parathyroid glands the esophagus larynx and trachea and also a number of lymph glands. The base of the posterior triangle is formed by the middle third of the clavicle. The posterior neck triangle is a clinically relevant anatomic region that contains many important vascular and neural structures.

A significant muscle in the posterior triangle region is the omohyoid muscle. Anatomy of the neck the neck contains a number of overlapping muscles blood vessels nerves and myriad structures all contained in a small space and liable to damage and distress. Posterior nodes the posterior triangle contains lymph nodes that are arranged into two groups.

The borders of the posterior triangle of the neck are formed by the trapezius muscle posteriorly the sternocleidomastoid muscle anteriorly and the omohyoid muscle inferiorly. It is split into two bellies by a tendon.
