25
Identify the structures the arrows are pointing to (from top to bottom of picture).
1. epiglottis 2. vestibular fold 3. vocal fold
26
Identify the structure.
Arytenoid cartilage
27
The CRICOTHYROID MUSCLES are innervated by the _________ and cause the thyroid cartilage to tilt \_\_\_\_\_\_, causing tightening and _______ in pitch.
- EXTERNAL LARYNGEAL n. - anteriorly - increasing
28
Name the structures. Is the nerve in the image innervating the muscle in the image?
cricoid trachea cricothyroid muscle recurrent laryngeal n. -NO! the EXTERNAL LARYNGEAL innervates crcothyroid m.
29
The _________ pulls the arytenoid cartilages together, shortening the width of the airway. Name the nerve this muscle is innervated by.
TRANSVERSE ARYTENOID m. recurrent laryngeal n.
30
The OBLIQUE ARYTENOID MUSCLES adjust the size of the ______ and are innervated by the _______ nerve
- laryngeal inlet - recurrent laryngeal
31
The _______ attach to the musclular part of the arytenoid cartilage to the cricoid cartilage, pulls muscular processes _______ to ______ the volcal folds. These muscles are innervated by the __________ nerve.
- posterior cricoarytenoids - medially - ABduct (OPEN!!) - recurrent laryngeal
32
The ________ pull the arytenoid cartilages anteriorly to decrease tension on the vocal ligaments, ____ the pitch of the voice. This muscle is innervated by the _______ nerve.
- THYROARYTENOIDS - decreasing - recurrent laryngeal
33
The \_\_\_\_\_\_, located from the arytenoid to the lateral part of the cricoid, pull anteriorly to ADduct the vocal folds, thus closing the rima glottidic. This muscle is innervated by the _____ nerve.
- lateral crioarytenoid muscle - recurrent laryngeal
34
The ______ laryngeal nerve supplies sensory and motor innervation the larynx and pierces the thyrohyoid membrane.
SUPERIOR
35
The ______ laryngeal nerve provides sensory to the mucosa superior to the vocal folds and ANS innervation.
Internal
36
The _______ laryngeal nerve provides motor innervation to the CRICOTHYROID m.
EXTERNAL
37
The _______ laryngeal nerve provides sensory to the mucosa inferior to vocal folds and motor to all intrinsic m. of larynx (except \_\_\_\_\_\_\_\_\_).
- RECURRENT - cricothyroid
38
What artery supplies the LARYNX?
SUPERIOR LARYNGEAL
39
[Figure I] shows open vocal cords. [Figure II] shows closed vocal cords. What is wrong with Figure III? What nerve is damaged?
the left recurrent laryngeal n is paralyzed and so there is unilateral vocal cord paralysis
