1.In the larynx
a) Presence of the cricothyroid joint allows the vocal ligaments to vary their length
b) Posterior cricoarytenoid muscles are the only abductors of the vocal cords
c) Mucous membrane below the vocal cords is supplied by the recurrent laryngeal nerve
d) Vocal ligaments cannot be lengthened when the recurrent laryngeal nerve is completely damaged
e) Piriform fossa ties between the vestibular and vocal folds
2.Regarding the larynx
a) Edema fluid collects in the submucosa of the vocal cords
b) vestibular folds lie further apart than the vocal cords
c) Free superior edge of the cornus elesticus is the vocal ligament
d) posterior cricoarytenoid muscle is attached to the muscular process of the arytenoids cartilage
e) vocal ligament the thickened lower edge of the quadrangular membrane
3.Regarding the larynx
a. Epigtottic tubercle can be seen by laryngoscopic examination
b. Lymph above the vocal folds passes along the superior laryngeal vessels
c. Mucous membrane above the vocal folds supplied by the recurrent laryngeal nerve
d. Ery-epigtottic fold shortens during swallowing
e. Vocal cords are tax when the recurrent laryngeal nerve is completely damages
4.Regarding the larynx
a) Vocal ligament is the free superior edge of the lateral cricothyroid ligament
b) In quiet respiration, Rima glottides is diamond shaped
c) In oedema of the larynx, fluid collects in the loose submucosa of the vocal folds
d) Lateral cricoarytenoid rotates the arytenoids cartilage medially to adduct the vocal folds
e) Vestibular folds lie further apart than Vocal
