34. Nerves

35. Spinal Accessory Nerve In 70% cases it lies lateral to IJV. Crosses lateral to the transverse process of the atlas. Supplies motor input to sternocleidomastoid exits at Erb s point. ▶ Runs across posterior triangle. ▶ Leaves posterior triangle by passing deep to anterior border of trapezius 5cm above clavicle. grays anatomy students edition

36. Cervical plexus

37. Blood vessels

38. External jugular vein ▶ Superficial vein ▶ Formed by union of – post auricular and retromandibular vein ▶ Originates at angle of mandible ▶ Drains into subclavian vein grays anatomy students edition

39. Internal Jugular V e i n ▶ It is the continuation of sigmoid sinus and is the thin walled capacitance vessel ▶ IVJ joins the subclavian vein to form brachiocephalic vein at the level of sternal end of the clavicle Tributaries are: inferior petrosal vein, facial, lingual, pharyngeal, superior and middle thyroid veins Deep cervical lymph nodes II,III,IV are found on the superficial surface of the vein.
