|
When the two laminae of thyroid cartilage meet, the anterior bump is called the _________ _______
|
laryngeal prominence
|
|
|
|
Between the hyoid bone and the superior border and horns of the thyroid cartilage is the ________ ____________
|
thyrohyoid membrane
|
|
|
|
Between the upper border of the cricoid cartilage and the lower border of the thyroid is a fibrous membrane called _______ ________, which is continuous with the ________ _________
|
conus elasticus, vocal ligaments
|
|
|
|
The concavity between the vestibular and vocal folds of each side is called the _________ _______
|
laryngeal ventricle
|
|
|
|
At the anterior end of the larnygeal ventricle, a tubular extension, the ___________ _______extends upward, and may become pathologically dilated, a ________
|
laryngeal saccule, laryngocele
|
|
|
|
The 5 major movers of the vocal cords

|
All of the muscles of the larynx are innervated by ___________ except for the _________ which is innervated by ____________
|
the recurrent(inferior) laryngeal nerve, cricothyroid, external branch of the superior laryngeal
|
None
|
|
|
Name the Cough Reflex's afferent and efferent nerves and the area they innervate
|
Afferents - internal branch of superior laryngeal = supraglottic mucosa, - vagus X, via recurrent laryngeal and some cranial accessory XI = infraglottic mucosa....Efferents - recurrent laryngeal adducts the vocal cords - phrenic to the diaphragm - abdominopelvic nerves to muscles of abdomen
|
|
|
|
Name the Gag Reflex's afferent and efferent nerves and the area they innervate
|
Afferent -glossopharyngeal IX = pharyngeal mucosa Efferent - vagus X = pharyngeal constrictors
|
|
|
|
Normal response to unilateral pharyngeal stimulation
|
bilateral contraction of pharyngeal constrictors
|
|
|
|
Effect of unilateral destructive lesion of Vagus X on pharyngeal constrictors
|
contraction of muscles on healthy side only, thus "curtain deviation" away from lesion
|
None
