Q

salivary glands and ducts

A

parotid and submandibular glands

24
Q

facial artery

A

brings a large supply of arterial blood to the facial muscles

25
Q

The facial artery is a branch of the?

A

external carotid artery

26
Q

What nerves are responsible for facial movement and facial sensation?

A

the facial nerve (CN VII) and the trigeminal nerve (CN V)

27
Q

the facial nerve transmits

A

motor information to facial muscles from the brain

28
Q

the trigeminal nervce carries

A

the bulk of the sensory information to facial muscles from the brain

29
Q

trigeminal nerve

A

has 3 branches

30
Q

Temporalis and masseter muscles (2 of the 3 muscles of mastication) are innervated by

A

the trigeminal nerve, specifically the mandibular branch, V3, to transmit motor output

31
Q

Buccinator (3rd mastication muscle)

A

is innervated by the facial nerve

32
Q

the digastric is innervated by 2 different nervces

A

facial and trigeminal

33
Q

anterior belly of the digastric muscle is innervated by

A

the trigeminal nerve

34
Q

posterior belly of the

digastric is innervated by

A

the facial nerve

35
Q

Frontalis

A

temporal branch

36
Q

corrugator supercilii

A

temporal branch

37
Q

orbicularis oculi

A

temporal (superior); zygomatic (inferior) branch

38
Q

zygomaticus major/minor

A

zygomatic and buccal branch

39
Q

levator anguli oris

A

zygomatic and buccal branch

40
Q

levator labii superioris alaeque nasi

A

zygomatic and buccal branch

41
Q

buccinator

A

buccal branch

42
Q

risorius

A

buccal branch

43
Q

orbicularis oris

A

buccal and marginal mandibular branch

44
Q

depressor anguli oris

A

marginal mandibular branch

45
Q

depressor labii inferioris

A

marginal mandibular branch

46
Q

mentalis

A

marginal mandibular branch

47
Q

platysma

A

cervical branch

48
Q

“the Elvis” muscle

A

levator labii superioris alaeque nasi

49
Q

Swallowing has __ steps

A

5

50
Q

step 1

A

the tongue and buccinator muscles move the food bolus towards the back of the mouth towards the pharynx.

51
Q

step 2

A

the suprahyoid muscles pull the hyoid superiorly and anteriorly towards the mandible, which then widens the pharynx and moves the larynx under the epiglottis (remember, the larynx is anterior to the pharynx). The other 3 suprahyoid muscles that aid in “lifting” the hyoid bone are: stylohyoid, geniohyoid, and mylohyoid muscles

52
Q

step 3

A

small muscles elevate the soft palate and close off nasal passages—these muscles are called tensor veli palatini and levator veli palatini. The palatini muscles that aid in elevation of the soft palate are located superiorly to the soft palate.

53
Q

step 4

A

the food gets propelled inferiorly in the esophagus by pharyngeal constrictor muscles of the pharynx. The pharyngeal constrictor muscles include: the superior, middle, and inferior pharyngeal constrictor muscles. These muscles wrap themselves around the pharynx.

54
Q

step 5

A

infrahyoid muscles “reset” the positions of the hyoid and larynx by pulling the hyoid posteriorly and inferiorly back into position, thus ending the act of swallowing

55
Q

a dysfunction in the inability to swallow appropriately

A

oropharyngeal dysphagia
