The laryngeal cartilages are ____ and subject to later life ___________
hyaline, calcification
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
1 - posterior cricoarytenoid 2 - arytenoid 3 - cricothyroid 4 - lateral cricoarytenoid 5 - thyroarytenoid
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
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
