Lesson 5 Flashcards
what are the vital functions of the phonatory system?
- protecting the lungs
- assisting in performance of physically demanding tasks
whats two other names for the phonatory system?
laryngeal and voicing
what makes up the larynx
- cricoid
- arytenoid
- thyroid
- epiglottis
- corniculates and cuneiforms
- hyoid bone
- laryngeal ligaments and membranes
what parts on the larynx are made of hyaline cartilage?
- cricoid
- arytenoids
- thyroid
- corniculates and cuneiforms
what part of the larynx is made of elastic cartilage?
epiglottis
- right on top of the trachea
- specialized trachea ring
cricoid
how do you name a processes?
by what they connect to
- has the muscular process
- has the vocalic process
- has an apex
- on each side of the cricoid
- asymmetrical
arytenoids
- largest cartilage in the larynx
- symmetrical
- can pivot on lower cornua
- the lower cornua attaches to cricoid
thyroid
- leaf/heart shaped
- attached with a ligament to the thyroid
- vital for swallowing
- irrelevant for speech and breathing
epiglottis
courses between the inside of the thyroid angle and the vocalic processes of the arytenoid cartilages
part of the vocal folds
vocal ligament
muscles connecting parts of the larynx to eachother
intrinsic muscles
muscles connecting the larynx to structures outside the larynx
extrinsic muscles
these muscles abduct and adduct the vocal folds and affect vocal fold tension
intrinsic laryngeal muscles
- vocalis
- external or lateral thyroarytenoid
- cricothyroid
- posterior cricoarytenoid (PCA)
- lateral cricoarytenoid (LCA)
- transverse aryetnoid
- oblique arytenoid
intrinsic laryngeal muscles
what is the origin of the internal thyroarytenoid (vocalis)?
angle of thyroid
what is the insertion of the internal thyroarytenoid (vocalis)?
vocal process of arytenoid
