6
Q
what does “Ingestion” mean in regards to swallowing ?
A
Protect respiratory system from entry of foreign material (In adults, upper respiratory and digestive paths are crossed)
7
Q
what are the main structures involved in swallowing ?
A
- oral cavity
- pharynx
- trachea
- esophagus
- nasal cavity
8
Q
define the “oral cavity” in regards to being a structure involved in swallowing ?
A

- tongue ( helps create bolus)
- teeth (chew)
- saliva (enzymes that help break down)
9
Q
define the “nasal cavity” in regards to being a structure involved in swallowing ?

- lifts up so thigs don’t go up nasal cavity
10
Q

13
Q
how many stages of swallowing are there ?
A
3
14
Q
what are the 3 stages of swallowing ?
A
- Oral (transfer)
- Pharyngeal (transport)
- Esophageal (entrance)
15
Q
describe the purpose of stage #1 (Oral (transfer)) :
A
To prepare substance to be swallowed and move
bolus to rear of oral cavity until swallow reflex is triggered (in
pharyngeal phase)
16
Q
how does stage #1 (Oral (transfer)) occur ?
A
– Begins when food/liquid enters mouth (lips sealed)
– Tongue and cheek muscles move material for mastication
– Saliva softens food to help create a bolus
– Posterior tongue action that moves the bolus back
– Ends when bolus passes through anterior faucial arches and swallowing reflex is initiated
17
Q
describe the purpose of stage #2 (Pharyngeal phase (transport)) :
A
To propel bolus through pharynx to entrance to esophagus
18
Q
how does stage #2 (Pharyngeal phase (transport)) occur ?
A
Starts when swallow reflex (involuntary) is triggered
- Velum raises (velopharyngeal closure)
- Pharynx contracts and squeezes
- Larynx moves up and closes (vocal folds close, epiglottis lowers)
- Reflexive contractions of pharyngeal muscles moves bolus towards the esophagus
- Upper esophageal sphincter opens
19
Q
how does stage #3 (Esophageal phase) occur ?
A
- Muscles of esophagus move bolus down to stomach in peristaltic contractions
- Food propelled through esophagus by peristatic action (and gravity) towards the stomach
- Not under voluntary control
- After bolus enters esophagus, breathing returns to normal
20

- Swallow dyed food (blue or green)
- May reveal premature spillage,
airway closure
68
what is the ultrasound assessment of dysphagia ?
Ultrasound is a non-invasive imaging technique that uses sound waves to create images of structures inside the body. In the context of dysphagia, ultrasound is primarily used to assess oral and pharyngeal swallowing mechanics.
69
what is the Electromyography assessment of dysphagia ?
Electromyography (EMG) is a diagnostic tool used to measure the electrical activity of muscles. It can be applied to assess the function of muscles involved in swallowing, specifically those in the pharyngeal and laryngeal areas.

you cannot see to confirm aspirating (we cannot see like we can on x-ray
75
how does Ultrasound Assessment of Dysphagia work ?
High-frequency sound waves are directed at the throat and mouth during swallowing. The ultrasound waves are reflected off the tissues, creating real-time images (or videos) of the structures involved in swallowing.
76
how does Electromyography (EMG) for Dysphagia work ?
Small electrodes are placed on the skin (surface EMG) or inserted into muscles (intramuscular EMG) to detect electrical signals produced by muscle activity. These signals are recorded and analyzed to assess the timing, strength, and coordination of muscle contractions during swallowing.
77
what are some advantages of ultrasound Assessment of Dysphagia ?

what are some limitations of ultrasound Assessment of Dysphagia ?
- Limited ability to view deeper structures such as the esophagus.
- May not provide detailed information about the larynx or vocal cords.

- Can help in diagnosing neuromuscular disorders that affect swallowing, such as stroke, Parkinson’s disease, or amyotrophic lateral sclerosis (ALS).
80
what are some limitations of Electromyography (EMG) assessment of dysphagia ?

- Oral phase duration
- Structure/movement of hyoid bone and tongue
(put it under tongue to see)
82
