Exam 2- Veins

External Jugular Vein

Formed by union of posterior division of retromandibular vein and posterior auricular vein

Runs vertically superficial to SCM

Drains into subclavian

Internal Jugular Vein

Begins at jugular foramen on skull

Runs laterally within carotid sheath

Ends by joining subclavian vein to form brachiocephalic vein

Subclavian Vein

Begins at lateral border of first rib

Passes anterior to anterior scalene muscle

Joins internal jugular vein to form brachiocephalic vein

Venous Angle

IJV + subclavian veins

Lymphatic vessels end at venous angles

Retromandibular Vein

Formed from union of superficial temporal vein and maxillary vein

Deep vein

Posterior to ramus of mandible

Terminal branches: posterior and anterior branch

Anterior branch of retromandibular vein

Facial Vein: continuous with angular vein

Common Facial Vein: formed from anterior branch of retromandibular and facial vein

Posterior Branch of Retromandibular Vein

Posterior auricular vein

External jugular vein: formed from union of posterior branch of retromandibular and posterior auricular

Venous Return from Face

Angular vein forms at medial canthi

Tributaries: external nasal, superior labial, deep facial, inferior labial vein

Common Facial Vein

Formed by union of facial v, submental, lingual, and anterior division of retromandibular

Empties into IJV

Pterygoid Venous Plexus

Network of veins accompanying maxillary artery

Forms maxillary vein (very short) that drains into retromandibular vein

Communicates with: cranial cavity- cavernous sinus, orbit-inferior ophthalmic veins, superficial face- deep facial vein, neck- retromandibular vein
