INTERNAL JUGULAR VEIN

Back 1

E. Internal jugular vein: descends within the carotid sheath lateral to the
internal/common carotid artery; receives the superior thyroid, middle thy-
roid, pharyngeal, lingual, occipital, and common facial veins

Front 2

SUBCLAVIAN VEIN

Back 2

F. Subclavian vein: receives the external jugular vein which, in turn, receives
the suprascapular and transverse cervical veins; the vertebral, internal tho-
racic, inferior thyroid, and deep cervical veins drain into the brachiocepha-
lic vein

Front 3

DEEP CERVICAL NODES

Back 3

G. Lymphatics

1. Deep cervical nodes: located within and around the carotid sheath and
receive lymphatic drainage from the head and neck via submental, sub-
mandibular, retropharyngeal, occipital, retroauricular, superficial and
deep parotid, and superficial cervical nodes; inferiorly, they drain into
the jugular lymphatic trunk

Front 4

SUPERFICIAL CERVICAL NODES

Back 4

G. Lymphatics

2. Superficial cervical nodes: lie along the external jugular vein; receive
lymphatic drainage from occipital, retroauricular, and superficial and
deep parotid nodes, and drain to deep cervical nodes

Front 5

THORACIC DUCT

Back 5

3. Thoracic duct: courses laterally, anterior to the left vertebral artery, and empties into the angle of junction ofthe left subclavian and left internal
jugular veins; near its termination it receives the left jugular, left sub-
clavian, and left bronchomediastinal trunks
