Unpaired laryngeal cartilages Flashcards
exam 2
True or false:
The hyoid bone is technically not a part of the larynx
True
What is the largest cartilage that protects most of the laryngeal wall?
Thyroid cartilage
______ horns articulate with the hyoid bone through lateral thyrohyoid ligaments
Superior thyroid cornua
______ horns articulate with the cricoid cartilage at the ‘facet for the thyroid’ forming the cricothyroid joint
Inferior thyroid cornua
The thyroid tilts/rocks forward and backward at this joint changing the vocal fold length/tension
Cricothyroid joint
The cartilage located below the thyroid notch is called the what?
Thyroid prominence
What cartilage looks like a signet ring seen from the side?
Cricoid cartilage
What cartilage sits above the top of the 1st tracheal ring?
Cricoid cartilage
What cartilage has the cricothyroid joint at the inferior facets and the cricoarytenoid joint at the superior facets?
Cricoid cartilage
Joint between the lower cornua of the thyroid and the lower facet (lateral facet) of the cricoid
Cricothyroid joint
Contraction of muscles in the cricothyroid joint does what to the vocal folds?
lengthen/tense the vocal folds
Relaxation of muscles in the cricothyroid joint does what to the vocal folds?
Allows vocal folds to return to rest length and tension
What cartilage is leaf shaped?
Epiglottis cartilage
What cartilage covers the opening of the larynx during swallowing?
epiglottis
Where is the epiglottis connected to (3 places) via ligament?
Thyroid - thyroepiglottic ligament
Hyoid - Hypoepiglottic ligament
Tongue - Glossoepiglottic ligament
