Gross anatomy ------------------------ Origin and course It is formed by the union of inferior petrosal and sigmoid dural venous sinuses in or just distal to the jugular foramen (forming the jugular bulb). It descends in the carotid sheath with the internal carotid artery. The vagus nerve (CN X) lies between the two. After receiving tributaries from the face and neck (listed below) it continues to descend before descending into the thorax, usually between the heads of the sternocleidomastoid muscle, before uniting with the subclavian vein to form the brachiocephalic vein. Tributaries ------------------ inferior petrosal sinus pharyngeal veins facial vein lingual vein superior thyroid vein middle thyroid vein A handy mnemonic to recall the internal jugular vein is: --------------------------------------------------------------------------------------- Medical Schools Let Fun People In Relations --------------- surrounded by accompanying lymph nodes relation to internal carotid artery C2: posteriorly C3: posterolaterally C4: laterally vagus nerve (CN X) always situated between the ICA and IJV anteriorly (i.e. is crossed by these structures) upper third: spinal root of accessory nerve (CN XI) middle third: lower root of ansa cervicalis lower third: sternocleidomastoid muscle, tendon of omohyoid muscle posteriorly (from superior to inferior as the IJV descends in the neck) lateral mass of C1 (atlas) middle scalene muscle anterior scalene muscle pleura of lung apices #internaljugularvein #jugularvein #anatomy #usmle #usmlestep1 #mbbs #anatomyanimations #anatomyvideos #anatomyvideolectures #anatomyusmle
