ability to strip bolus from utensil

49
Q

A

the receptors provide information about bolus volume and taste. Understanding what your bolus is

50
Q

Using the tongue to shape and move the bolus

52

A

Rotary movement of the tongue. Vallecular aggagation

53
Q

Is the soft palate down during chewing?

A

NO

54
Q

What are the cranial nerves involved in chewing?

A

CNV: Muscles of mastication. Elevate the mandible to close the mouth, side to side movement of mandible.
CNXII: Intrinisic+extrinisic muslces of the tongue: Move bolus to surface of teeth for chewing and assist with bolus formation. Oral containment
CNVII: Facial muscles and lips. Compress cheeks against teeth. Oral containment
CNV and CNVII: Suprahyoid. Stabalize floor of mouth to assist with chewing and tongue movement. Depress mandible for open mouth.

55
Q

Describe oral transport

A

Brisk and coordinated movement of tongue without delay. Same muscles as above minus mastication.

description for reference:
•CN XII (hypoglossal): Intrinisic muscles of the tongue à press tongue against palate to move bolus posteriorly, maintain cohesive shape of bolus between tongue & palate
•CN XII (hypoglossal) and X (vagus): extrinsic muscles of the tongue: position tongue against palate to move bolus posteriorly
•CN V (trigeminal), VII (facial): suprahyoid muscles à stabilize floor of mouth to maximize efficiency of tongue movement

56
Q

How long does oral transport take?

A

1-1.5 seconds.

57
Q

Describe: pharyngeal swallow onset

A

a motor response. The soft palate elevates and retracts, the larynx elevates, anterior hyoid movement, epiglottic inversion, laryngeal vestibular closure, pharyngeal stripping wave, contraction, PES opening, tongue base retraction.

58
Q

What cranial nerves are involved with pharyngeal swallow onset

A

CNIX and X

59
Q

Describe soft palate elevation

A

The soft palate elevates and retracts, pushes bolus back to the nasopharynx. Velopharyngeal closure and hyolaryngeal movement occur simultaneously.

60
Q

What is the primary generator of positive pressure against to bolus tail and a mechanism of airway protection?

A

Base of tongue retraction

61
Q

Describe laryngeal elevation

A

Shortening and contracting of the thyrohyoid. Intrinsic muscles of the larynx cause the downward, inward, and forward rotation of the arytenoid cartilages to the epiglottic base. True vocal folds close and approixmate the ventricular folds.

62
Q

Describe: Anterior hyoid excursion

A

Sometimes called hyolaryngeal complex. The hyoid moves up and forward.

63
Q

Describe: Pharyngeal stripping wave

A

The stripping action of the pharynx achieved by sequential progressive contraction of the superior, middle, and inferior pharyngeal constrictor muscles.

64
Q

Describe: Laryngeal Vestibule closure

A

Laryngeal elevation, anterior hyoid excursion, epiglottic inversion, tongue base retraction, vocal fold closure.

65
Q

Define: Penetration

A

bolus dips into the laryngeal vestibule but moves back out. Always above the vocal folds.

66
Q

What is a normal response to penetration?

A

A dry swallow

67
Q

Define Aspiration

A

Below vocal folds. Silent aspiration = no audible cough response.

68
Q

Define: Residue

A

Material left in oral cavity, pharynx, esophegues, or laryngeal vestibule post-swallow.

69
Q

List the steps in the oropharyngeal phase (14)

A

throat clearing, wet voice, coughing.

80
Q

What would cause aspiration/penetration BEFORE the swallow?

A

reduced oral control, early loss of bolus, delay of swallow

81
Q

What would cause aspiration/penetration AFTER the swallow?

A

overflow of residue, problem with UES

82
Q

What would cause aspiration/penetration DURING the swallow?

Incomplete vestibular closure, decreased hyolaryngeal movement, glottic closure trouble, reduced PES

83
Q

What are the names of the 3 mentioned esophegeal deficits?

A

Cricopharyngeal prominence, cervical esophegus web, Zenkers (herneation in the cervical esophegus)

Q

What are the goals of a swallow screen

A

Pass/Fail, ID who needs a rx for an SLP consult

85
Q

What are the steps of an inital clinical swallow eval?

A

Not instrumental. 1. ID the presence or absence of dysphagia. 2. Determine need for instrumental assessment (be sure to outline the specific questions you want to have answered by the assessment.3. Determine dx or oral dysphagia.

86
