The deep venous drainage is via the pterygoid venous plexus.

Neck vein anatomy. The suprascapular transverse cervical and anterior jugular veins join the external jugular vein in the posterior triangle. The oblique jugular vein interacts with all the internal jugular vein in the upper part of the neck. The left and right common carotid arteries ascend up the neck lateral to the trachea and the oesophagus.

At the level of the superior margin of the thyroid cartilage c4 the carotid arteries split into the external and internal carotid arteries. The main vessels are the external jugular vein and the interior jugular vein. Neck in land vertebrates the portion of the body joining the head to the shoulders and chest.

It also includes the veins that return deoxygenated blood from these organs to the heart. In the neck the internal jugular vein descends within the carotid sheath deep to the sternocleidomastoid muscle and lateral to the common carotid artery. At the base of the neck posteriorly to the sternal end of the clavicle the ijv combines with the subclavian vein to form the brachiocephalic vein.

A little above its termination is a second dilatation the inferior bulb. The external jugular vein receives blood from the neck the outside of the cranium and the deep tissues of the face and empties into the subclavian veins continuations of the principal veins of the arms or forelimbs. They do not give off any branches in the neck.

As the tooth tapers below the gumline the neck is formed. It runs down the side of the neck in a vertical direction lying at first lateral to the internal carotid artery and then lateral to the common carotid and at the root of the neck unites with the subclavian vein to form the innominate vein. Some important structures contained in or passing through the neck include the seven cervical vertebrae and enclosed spinal cord the jugular veins and carotid arteries part of the esophagus the larynx and vocal cords and the sternocleidomastoid and hyoid muscles in front and the trapezius and other nuchal muscles behind.

They do not give off any branches in the neck. Immediately prior to this the inferior end of internal jugular vein dilates to form the inferior bulb. The cardiovascular system of the head and neck includes the vital arteries that provide oxygenated blood to the brain and organs of the head including the mouth and eyes.

Below the neck holding the tooth into the bone is the root of the tooth. The superficial veins of the scalp starting anteriorly and moving posteriorly are the supratrochlear and supraorbital veins respectively the superficial temporal veins and its branches the posterior auricular vein and the occipital vein and its branches.
