Normal variability in swallowing means that the swallow can be elicited with the bolus head in the oral cavity or as deep as the pyriform sinuses.
True!!
FALSE!!
I'm not sure!
Allowing certain types of foods (i.e. mixed consistencies) to enter the valleculae before the swallow is initiated is normal and termed 'vallecular aggregation'
True!!
FALSE!!
I'm not sure!
Swallow initiation times do not vary depending on whether the swallow initiates spontaneously versus when someone tells you to swallow (command swallow).
True!!
FALSE!!
I'm not sure!
The following is true about swallow trigger:
It is an all-or-none event
It initiates the cascade of swallowing events
It has a wide range of normal variability
It can be measured
All of the above
Hyoid movement is a representation of numerous muscles that control its movement and is patterned by the brainstem and multiple cranial and spinal nerves.
True
False
I'm not sure!
Pick one statement which is NOT true about normal Laryngeal Vestibule Closure (LVC):
he laryngeal vestibule is open during non-swallow periods to allow breathing
The laryngeal vestibule closes during swallowing at various levels
Laryngeal Vestibule Closure marginally impacts swallowing safety
Laryngeal Vestibule Closure can be measured
Laryngeal Vestibule Closure relies on lingual movement
LVC relies on movements due to the following sources:
a) movements caused directly (brain programs muscles to contract causing movement)
b) movements caused indirectly (forces applied by a nearby structure)
c) Both A&B
d) None of the above
UES opening relies on the following to open normally (please select two responses):
large bolus volumes
hyoid elevation
laryngeal elevation
relaxation
lingual elevation
The UES is responsive to bolus volume in the following way:
Larger bolus volumes lead to longer opening durations
Larger bolus volumes lead to shorter opening durations
This is a trick question. The UES is a part of the reflexive component of swallowing and is not responsive to bolus volume.
Timing involves events that consider only the bolus, only physiology, or a combination of both.
True
False
I'm not sure
Allowing certain types of foods (i.e. mixed consistencies) to enter the valleculae before the swallow is initiated is normal and termed 'vallecular aggregation'
True!
False!
I'm not sure!
To determine how deep the bolus travelled before swallow onset occurred, you must consider two events (please select two responses):
Presence of premature spillage
Volitional bolus hold time
Bolus position
Swallow onset time marked by hyoid burst
Swallow onset marked by laryngeal elevation
