The nerves descend in the posterior triangle of the neck beneath the platysma muscle and the deep cervical fascia. [citation needed] Near the clavicle, the supraclavicular nerves perforate the fascia and the platysma muscle to become cutaneous. They are arranged, according to their position, into three groups—anterior, middle, and posterior.
Injury to Erb's point is commonly sustained at birth or from a fall onto the shoulder.The nerve roots normally involved are C5 and partly C6. Symptoms include paralysis of the biceps, brachialis, and coracobrachialis (through the musculocutaneous nerve); the brachioradialis (through the radial nerve); and the deltoid (through the axillary nerve).
Eagle syndrome (also termed stylohyoid syndrome, [1] styloid syndrome, [2] stylalgia, [3] styloid-stylohyoid syndrome, [2] or styloid–carotid artery syndrome) [4] is an uncommon condition commonly characterized but not limited to sudden, sharp nerve-like pain in the jaw bone and joint, back of the throat, and base of the tongue, triggered by swallowing, moving the jaw, or turning the neck.

The head and neck are emptied of blood by the subclavian vein and jugular vein. Right side of neck dissection showing the brachiocephalic, right common carotid artery and its branches. The brachiocephalic artery or trunk is the first and largest artery that branches to form the right common carotid artery and the right subclavian artery.
Pain can also be in the side of the neck, the pectoral area below the clavicle, the armpit/axillary area, and the upper back (i.e., the trapezius and rhomboid area). Discoloration of the hands, one hand colder than the other hand, weakness of the hand and arm muscles, and tingling are commonly present.
The triangles of the neck describe the divisions created by the major muscles in the region.. The side of the neck presents a somewhat quadrilateral outline, limited, above, by the lower border of the body of the mandible, and an imaginary line extending from the angle of the mandible to the mastoid process; below, by the upper border of the clavicle; in front, by the middle line of the neck ...
The great auricular nerve is a cutaneous (sensory) nerve of the head. It originates from the second and third cervical (spinal) nerves (C2-C3) of the cervical plexus.It provides sensory innervation to the skin over the parotid gland and the mastoid process, parts of the outer ear, and to the parotid gland and its fascia.
The vagus nerves, from which the recurrent laryngeal nerves branch, exit the skull at the jugular foramen and travel within the carotid sheath alongside the carotid arteries through the neck. The recurrent laryngeal nerves branch off the vagus, the left at the aortic arch, and the right at the right subclavian artery. The left RLN passes in ...
