Q

Hyoglossus

A

Differential response based on where the muscle is fixed. If fixed at the tongue, will elevate the hyoid. If fixed at the hyoid, will retract and depress the tongue.

16
Q

Genioglossus

A

Protrudes and depresses the tongue, aids in bolus transport. Makes tongue concave to help cup the bolus.
-hypoglossal (CN 12)

17
Q

Styloglossus

A

Draws the tongue up and back (ie. elevate and retract). Helps create pressure between tongue and palate to propel bolus to back of oral cavity.
-hypoglossal (CN 12)

18
Q

Palatoglossus

A

Elevates dorsum of tongue (to close off the oral cavity from the oropharynx) and draws the soft palate inferiorily. Lowers soft palate during nasal breathing.
-vagus nerve (CN 10)

19
Q

Intrinsic tongue muscles

A

-Together these muscles gather food from mental & lateral sulci, and direct it towards the chewing surfaces of the teeth.
-hypoglossal nerve (CN 8)
Super - superior longitudinal
Intelligent - inferior longitudinal
Very - verticalis
Tough - transverse

20
Q

Superior longitudinal

A

Draws the tip and sides of tongue up and shortens tongue. Makes top surface of tongue concave to hold a bolus.
-hypoglossal (CN 8)

21
Q

Inferior longitudinal

A

Draws tongue tip down and shortens tongue.

-hypoglossal (CN 8)

22
Q

Transverse

A

Narrows and elongates tongue

-hypoglossal (CN 8)

23
Q

Verticalis

A

Flattens and widens tongue, and helps establish a seal between the tongue and palate during swallowing.
-hypoglossus (CN 8)

24
Q

Muscles of the pharynx

A 
Pharyngeal plexus:
-So superior pharyngeal constrictor
-Much middle pharyngeal constrictor
-Candy cricopharyngeus
-To thyropharyngeus
Glossopharyngeal (CN 9)
-Swallow stylopharyngeus
-Pharyngeal plexus (minus accessory?)
-Speedily salpingopharyngeus
25
Q

Superior pharyngeal constrictor

A

Constricts the upper part of the pharynx; involved in sphincteric and peristaltic-like actions during swallowing.
-pharyngeal plexus (vagus, glossopharyngeal and accessory)

26
Q

Middle pharyngeal constrictor

A

Carries out sphincteric and peristaltic -like action in swallowing.
-pharyngeal plexus (vagus, glossopharyngeal and accessory)

27
Q

Cricopharyngeus

A
  • One of the two parts of the inferior pharyngeal constrictor. Involved in sphincteric and peristaltic-like action during swallowing; acts as a sphincter at the junction of the laryngopharynx and esophagus. Helps to prevent reflux.
  • pharyngeal plexus (vagus, glossopharyngeal and accessory)
28
Q

Thyropharyngeus

A
  • Most superior part of the inferior pharyngeal constrictor. Involved sphincteric and peristaltic-like actions during swallowing; acts as a “propulsive force” for swallowing
  • pharyngeal plexus (vagus, glossopharyngeal and accessory)
29
Q

Stylopharyngeus

A

One of the three muscles that forms the inner layer of the pharynx. Elevates and shortens pharynx during swallowing (pulls pharynx walls laterally, vertically shortens pharynx)
-glossopharyngeal (CN 9)

30
Q

Salpingopharyngeus

A

Elevates the pharynx and larynx to assist with deglutition. Opens the Eustachian tube to equalize pressure during swallowing and yawning (with TVP)
-pharyngeal plexus (vagus and glossopharyngeal, NO ACCESSORY?)

31
Q

Muscles of the supralarynx and area

A 
Trigeminal (CN 5):
-M mylohyoid
-A anterior belly of digastric
Facial (CN 7)
-P posterior belly of digastric
-S stylohyoid
Hypoglossal (CN 12)
-Go geniohyoid 
Vagus (CN 10)
-Pretty palatoglossus
Pharyngeal Plexus
-Places palatopharyngeus
-Constantly cricopharyngeus
32
Q

Myohyoid

A

Elevates hyoid bone during swallowing. moves the hyoid and tongue anteriorly, depresses mandible, assists in propelling the bolus as well as moving the hyolaryngeal complex anteriorly/superiorly during the swallow.
-trigeminal (CN 5)

33
Q

Anterior belly of digastric

A

Elevates hyoid bone during swallowing, depresses jaw if hyoid is fixed, moves hyolaryngeal complex
-trigeminal (CN 5)

34
Q

Posterior belly of digastric

A

Opens jaw when masseter and temporalis are relaxed, elevates/retracts hyoid bone, propels bolus and moves hyolaryngeal complex
-facial (CN 7)

35
Q

Stylohyoid

A

Draws the hyoid bone backwards, helps elevate the hyoid, and this combined action aids to elevate the tongue
-facial (CN 7)

36
Q

Geniohyoid

A

Protracts and elevates the hyoid bone and depresses the tongue
-hypoglossal (CN 12)

37
Q

Palatoglossus

A

Elevates dorsum of tongue (to close off the oral cavity from the oropharynx) and draws the soft palate inferiorly.
Lowers soft palate during nasal breathing.
-Vagus (CN 10)

38
Q

Palatopharyngeus

A

Tenses soft palate and pulls pharyngeal walls superiorly, anteriorly and medially during swallowing. Shortens the pharynx with the stylopharyngeus muscle during swallowing. Closes off nasopharynx from the oropharynx. Pulls the pharynx upward over the bolus of food and prevents it from passing into nasopharynx.

  • *Also involved with the muscles of the soft palate group and the muscles of the pharynx
  • pharyngeal plexus (vagus, glossopharyngeal, accessory)
39
Q

Cricopharyngeus

A

One of the two parts of the inferior pharyngeal constrictor. Involved in sphincteric and peristaltic action during swallowing; acts as a sphincter at the junction of the laryngopharynx and esophagus. Helps to prevent reflux.
-pharyngeal plexus (vagus, glossopharyngeus, accessory)
