    • serious complications from facial and dental infections
  6. Plexus

  7. Blood vessels communicate with each other by an _______ which is a _______
    • anastomosis
    • connecting channel among the vessels
  8. Venous sinuses are
    blood-filled spaces between two layers of tissue
  9. The major arteries that supply the head and neck include the ______ and ______. The origins of these two arteries are ______

  10. For the left side of the body, the common carotid and subclavian arteries arise directly from the
  11. For the right side of the body, the common carotid and subclavian arteries are ______ which is a ________ from the aorta
    • both branches from the brachiocephalic artery
    • direct branch
  12. The common carotid artery ends by dividing into the ____ and ______ at about the level of the ______
    • internal and external carotid arteries
    • larynx
  13. Just before the common carotid artery bifurcates it exhibits a swelling called the
    carotid sinus
  14. The subclavian artery arises ______ to the common carotid artery
  15. The internal carotid artery is the source of the ______ , which supplies the _____, _____ and _____
    • ophthalmic artery
    • eye, orbit and lacrimal gland
  16. As with the internal carotid artery, the external carotid artery begins _____ and supplies the ______
    • at the superior border of the thyroid cartilage
    • ˜extracranial tissue of the head and neck, including the oral cavity
  17. The external carotid artery has four sets of branches called the
    • ˜anterior branches
    • ˜medial branches˜
    • posterior branches
    • terminal branches
  18. There are three anterior branches from the external carotid artery:
    • ˜the superior thyroid
    • ˜the lingual
    • ˜the facial branches
  19. Superior thyroid artery has branches that supply the
    infrahyoid muscles, the sternocleidomastoid muscle, the muscles of the larynx, and the thyroid gland
  20. The lingual artery travels _______ to the ________ and supplies the ______ and the _______
    • anteriorly
    • apex of the tongue
    • suprahyoid muscles and floor of the mouth
  21. The sublingual artery is a branch off the ______ that supplies the _____
    • lingual artery
    • the mylohyoid muscle, sublingual salivary gland, and mucous membranes of the floor of the mouth
  22. The facial or _______ sometimes ______ with the lingual artery
    • external maxillary artery
    • share a common trunk
  23. Describe the direction of the facial artery
    The facial artery runs over the sublingual gland and then over the lateral border of mandible (can palpate the notch) and up past corner of mouth to the medial canthus of the eye
  24. The only medial branch of the external carotid artery
    ascending pharyngeal artery
  25. The small branches of the ascending pharyngeal artery supply the
    pharyngeal walls, soft palate, and meninges
  26. What are the two posterior branches of the external carotid artery
    occipital and posterior auricular
  27. Describe the direction of the occipital artery
    passes superiorly just deep to the ascending ramus of the mandible and then travels to the posterior part of the scalp
  28. The posterior auricular artery supplies the
    ˜internal ear and the mastoid air cells

    superficial temporal and maxillary
  30. The superficial temporal artery arises within the
    parotid salivary gland
  31. The superficial temporal artery has several branches including the
    transverse facial artery, the middle temporal artery, the frontal branch, and the parietal branch
  32. The small transverse facial artery supplies the
    parotid salivary gland duct and nearby facial tissue
  33. The equally small middle temporal artery supplies
    the temporalis muscle

  37. The second part of the maxillary artery gives rise to many branches within the
    infratemporal fossa
  38. The branches of the second part (or pterygoid part) within the infratemporal fossa include the
    middle meningeal and inferior alveolar arteries and several arteries to muscles
