Vascular anatomy of the neck.

Anatomy of neck veins. The lymphatic channels are found within the loose areolar tissue that exists around the internal jugular vein and within the carotid sheath. The neck carries the vital arteries transmitting blood to the brain head and face. At the root of the neck the right internal jugular vein is placed at a little distance from the common carotid artery and crosses the first part of the subclavian artery while the left internal jugular vein usually overlaps the common carotid artery.

The nodes occur anterior posterior and lateral to the vein. In the root of the neck the vein passes underneath the clavicle and terminates by draining into the subclavian vein. The neck also contains the cervical spinal cord as well as some important cranial nerves.

The head and neck are emptied of blood by the subclavian vein and jugular vein. Jugular vein any of several veins of the neck that drain blood from the brain face and neck returning it to the heart via the superior vena cava. The neck separates the head from rest of the body.

The major components present here include the jugular veins carotid arteries nerves a portion of the esophagus vocal cords or larynx cervical spine that encloses spinal cord and the sternocleidomastoid muscles. The anatomy of the neck comprises veins arteries nerves larynx thyroid glands cervical spine and other muscular structures. It also transmits the veins which drain the deoxygenated blood from the brain head and face and return it to the right side of the heart.

In the head superficial structures on the exterior of the skull are drained by the pair of external jugular veins which descend through the neck lateral to the vertebral veins. The veins of the scalp are present within the dense connective tissue which also contains nerves and arteries and the loose areolar connective tissue which also contains emissary veins that connect to the diploic veins of the skull and the intracranial venous sinuses. The main vessels are the external jugular vein and the interior jugular vein.

The left and right vertebral veins descend through the transverse foramina of the cervical vertebrae to drain blood from the spinal cord cervical vertebrae and muscles of the neck. The external jugular vein receives blood from the neck the outside of the cranium. 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.

Eighty percent of lymph nodes in the neck are closely associated with the internal jugular vein.
