    • Right common carotid artery
    • -supplies blood to head and neck
    • Right subclavian artery
    • -supplies blood to right upper limb
  10. Left common carotid artery
    • Arises at height of aortic arch
    • Supplies left side of head and neck
    • Passes upward and obliquely into neck
  11. Left common carotid artery bifucates at
    • C4/C5 level of thyroid cartilage
    • External carotid artery
    • Internal carotid artery
  12. Commom carotid arteries
    • Both pass upwards on either side of neck
    • Embedded in a fascia called the carotid sheath at upper thyroid cartilage C4/C5 divides into external and internal carotid arteries
  13. The commom carotid ateries are embedded in a fascia called
    Carotid sheath
  14. Left subclavian artery
    • Arises from upper convex surface of aortic arch
    • Both right and left pass under clavicle
    • Supplies left upper limb

    inguinal ligament
  29. The anterior tibial artery continues onto the dorsal surface of the foot to become
    dorsalis pedis
  30. The abdominal aorta bifurcates at what level
  31. LIst the 3 major branches off the aorta arch
