Jugular veins are the veins that take blood from the head to the heart via Superior Venacava (SVC).
Internal Jugular Vein (IJV) | External Jugular Vein (EJV) | |
Formation (Drains from) | Inferior petrosal sinus + Sigmoid sinus (At or just distal to Jugular foramen) | Posterior div. of retromandibular vein + Posterior auricular vein (Within parotid gland at the angle of mandible) |
Course | Carotid sheath (lateral-most) | Subcutaneous anterolateral neck (superficial then posterior to sternocleidomastoid) |
