Q

Trigeminal nerve

A

5
Largest cranial nerve
Motor: innervates muscles of mastication to help chew, clench teeth
Sensory: gives information about the size, hardness and temperature of bolus for chewing and swallowing

Q

Facial nerve

A

7
Motor: innervates muscles for facial expression, hyolaryngeal excursion and 2 salivary glands
Sensory: the sensation of taste (anterior 2/3 of tongue)

17
Q

Muscles of hyolaryngeal excursion (controlled by the facial nerve)

A

stylohyoid, posterior belly of digastric

18
Q

Muscles of facial expression

A

Obicularis oris, buccinator

19
Q

Glands innervated by the facial nerve

A

Submandibular, sublingual

20
Q

Glossopharyngeal nerve

A

9
Motor: provide movement to the stylopharyngeus (shortes and widens the throat)
Sensory: info from the throat, tonsils, middle ear, back of tongue, taste of posterior 1/3 tongue, gag reflex

21
Q

What does the stylopharyngeus do?

A

raises the pharynx, compresses the lateral laryngeal walls and helps pharyngeal compression over the food bolus during swallow

22
Q

Pharyngeal plexus

A

network of nerves that innervate the pharyngeal contractors

23
Q

Vagus nerve

A

10
motor: provides movement to the throat and soft palate (elevates the soft palate), pharyngeal constrictors, UES relaxation, peristaltic wave
sensory: provides general sensation of the epiglottis, pharynx, valleculae, pyriform sinuses, larynx/vocal folds,
swallow initiation, detecting pharyngeal residue, detecting aspiration, taste sensation of the epiglottis

24
Q

Muscles for velopharyngeal seal

A

Levator veli palatini

25
Q

Muscles for glossopalatal seal

A

Palatoglossus

26
Q

Accessory nerve

A

11

Motor: some muscles in the neck, part of pharyngeal plexus, allow a person to rotate, extend and flex neck and shoulders

27
Q

Hypoglossal nerve

A

12

motor: the nerve that supplies the tongue muscles,
