The external jugular vein commences in the substance of the parotid gland, on a level with the angle of the mandible, and runs perpendicularly down the neck, in the direction of a line drawn from the angle of the mandible to the middle of the clavicle superficial to the sternocleidomastoid muscle.
The internal jugular veins join with the subclavian veins more medially to form the brachiocephalic veins. Finally, the left and right brachiocephalic veins join to form the superior vena cava, which delivers deoxygenated blood to the right atrium of the heart. [2] The jugular vein has tributaries consisting of petrosal sinus, facial, lingual ...
Jugular groove: the line of indentation on the lower portion of the neck, can be seen from either side, just above the windpipe; beneath this area run the jugular vein, the carotid artery and part of the sympathetic trunk; Knee: the carpus of the horse (equivalent to the human wrist), the large joint in the front legs, above the cannon bone
The pterygoid plexus of veins becomes the maxillary vein. The maxillary vein and the superficial temporal vein later join to become the retromandibular vein. The posterior branch of the retromandibular vein and posterior auricular vein then form the external jugular vein, which empties into the subclavian vein. [citation needed]
The superficial cervical lymph nodes are lymph nodes that lie near the surface of the neck.. Some sources state simply that they lie along the external jugular vein, [1] while other sources state that they are only adjacent to the external jugular vein in the posterior triangle, and they are adjacent to the anterior jugular vein in the anterior triangle.
The great auricular nerve is a large trunk that ascends almost vertically over the sternocleidomastoid. [2] It winds around the posterior border of the sternocleidomastoid muscle, then perforates the deep fascia before ascending alongside the external jugular vein upon that sternocleidomastoid muscle beneath the platysma muscle to the parotid gland.

The superficial lateral cervical lymph nodes are found along the course of the external jugular vein, between the inferior aspect of the parotid gland and the supraclavicular nodes. The nodes are intercalated along the course of the vessels draining the parotid nodes and the infraauricular nodes.
