25

B: Zygomaticus Minor

facial artery

26

O: Orbicularis Oris

fibers derived from other facial muscles (buccinator, levators, and depressors of lips and angles, zygomatic muscles) pass into lips; also some intrinsic muscle fibers make up orbicularis oris

27

I: Orbicularis Oris

several strata of muscle fibers form a sphincter-like muscle with fibers that decussate at the angles of the mouth

28

A: Orbicularis Oris

closes the lips; and its deep fibers can press the lips against the teeth, also it protrudes the lips and is important in speech

29

N: Orbicularis Oris

buccal branch of the facial nerve (VII)

30

B: Orbicularis Oris

facial artery

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
