31

O: Buccinator

alveolar processes of mandible and maxilla opposite upper and lower molar teeth; posteriorly, it arises from the pterygomandibular raphe opposite superior constrictor

32

I: Buccinator

fibers course forward to blend into the formation of the orbicularis oris, decussating at the angles of the mouth

33

A: Buccinator

compresses the cheeks during chewing, also compresses the distended cheeks as in blowing a horn(!)

34

N: Buccinator

buccal branch of the facial nerve (VII)

35

B: Buccinator

facial artery

36

O: Orbicularis Oculi

medial palpebral ligament, nasal part of the frontal bone; frontal process of maxilla

37

I: Orbicularis Oculi

cross the eyelids and interlace to form the lateral palpebral raphe, froms ellipse around orbit without being interrupted on the lateral side

38

A: Orbicularis Oculi

closes the eyelids gently as in sleeping and blinking, closes the eyelids when a more forceful contraction is necessary as in winking one eye

39

N: Orbicularis Oculi

temporal and zygomatic branches of the facial nerve (VII)

40

B: Orbicularis Oculi

opthalmic artery

41

O: Levator Palpebrae Superioris

inferior aspect of lesser wing of sphenoid bone

42

I: Levator Palpebrae Superioris

medial and lateral walls of the orbit, superior tarsus

43

A: Levator Palpebrae Superioris

elevates the eyelid

44

N: Levator Palpebrae Superioris

occulomotor nerve (III)

45

B: Levator Palpebrae Superioris

branches of opthalmic artery

46

O: Superior Rectus

common annular tendon (which comes off the body and lesser wing of sphenoid), margins of the optic canal

47

I: Superior Rectus

posterior to the sclerocorneal junction (each muscle inserting along its own directional axis)

48

A: Superior Rectus

elevates, medially rotates, adducts the eye

49

N: Superior Rectus

occulomotor nerve (III)

50

B: Superior Rectus

branches of opthalmic artery

51

O: Inferior Rectus

common annular tendon (which comes off the body and lesser wing of sphenoid), margins of the optic canal

52

I: Inferior Rectus

posterior to the sclerocorneal junction (each muscle inserting along its own directional axis)

53

A: Inferior Rectus

depress, laterally rotates, adducts the eye

54

N: Inferior Rectus

occulomotor nerve (III)

55

B: Inferior Rectus

branches of opthalmic artery

56

O: Medial Rectus

common annular tendon (which comes off the body and lesser wing of sphenoid), margins of the optic canal

57

I: Medial Rectus

posterior to the sclerocorneal junction (each muscle inserting along its own directional axis)

58

A: Medial Rectus

adducts eye

59

N: Medial Rectus

occulomotor nerve (III)

60

B: Medial Rectus

branches of opthalmic artery
