All about the Nerves!
What cranial nerve is most likely impaired if you have a voice disorder?
Where is the ECM located?
What is outside of the cells.
What are the 3 layers of the LP?
What is the superficial, intermediate, and deep layers.
Who is more likely to have voice problems related to overuse of the VF?
What is females.
What 3 cortical areas are responsible for voicing?
What is precentral and post central gyrus, Broca's area, and the supplemental motor area.
Which branch of the Recurrent Laryngeal nerve travels down into the thorax, loops around the aorta, then ascends along the trachea to the larynx?
What is the left recurrent laryngeal nerve.
What is the function of the ECM?
What is it helps to define the quality of the voice by providing structure and support for the tissues and homeostasis between the cell and its surroundings. Cell adhesion, communication, differentiation.
What is the mucociliary blanket and where is it located?
What is a protective mechanism made of mucous that prevents dehydration and sits on top of the epithelium.
What is SLLP.
What are 3 higher brain functions concerned with voicing and speech?
Which branch of Vagus nerve has mixed motor and sensory fibers?
What is the Superior Laryngeal Nerve.
What are the 3 things that make up the ECM?
Fibrillar proteins, proteoglycans, GAGs.
What binds the epithelium to the SLLP?
What is the basement membrane zone.
What is the main difference between a cyst and a polyp?
What is vocal fold cysts have their own membrane.
What are the 3 areas of the cerebellum?
What is the vermis, pars intermedia, and hemispheres.
Of the SLN, which branch is responsible for sensations and which branch is responsible for motor activity?
What is the external branch is motor and the internal branch is sensory.
Which layer of the lamina propria has the highest density of hyaluronan?
What is the ILLP.
When there is injury or infection, what two things are more present in the SLLP?
What is macrophages and myofibrils.
What is a sulcus vocalis
What is the role of the thalamus in voicing?
What is integrating sensory information, coordination of outgoing information from other areas of the brain.
Which type of receptor is not present in the vocal folds? AND what does this mean for the vocal folds?
What is nociceptor. This means that our vocal folds do not feel pain, which often keeps us from recognizing/identifying a problem.
Which molecule in the ECM is known for being a catalyst of collagen?
What is Decorin.
Males have more HA in what layer of the LP?
What is SLLP.
What is often thought of as a laryngeal cancer protecting mechanism?
What is Reinke's Edema.
What system is "turned off" with vocal fold activity? AND What do we stay attuned to during vocal fold activity?
What is audition is turned off and we are attuned to frequency for the self regulation of pitch.
