Exam 1 Part 5 Flashcards
What makes up the cover (the outside mechanical layer) (3)?
Epithelium, superficial lamina propria, intermediate lamina propria
What makes up the body (the inside/deep mechanical layer) (2)?
Deep lamina propria, thyroarytenoid muscle
Term for combined intermediate and deep layer of the lamina propria
Vocal ligament
Vocal folds move as 2 linked mechanically different layer units
Body cover model
What makes up the vocal ligament?
Intermediate and deep layer of the lamina propria
T/F: According to Hirano’s cover-body model, the cover consists of deep layer of LP and TA muscle.
False
T/F: According to Hirano’s cover-body model, the body consists of deep layer of LP and TA muscle. Because, they both exhibit:
True
T/F: Fundamental frequency is the number of vocal fold vibrations per second.
True
T/F: Usually when false vocal folds are involved, we hear two pitches at the same time, as both true and false vocal folds generate two different fundamental frequencies. This phenomenon is called diplophonia.
True
Space between the vocal folds
Glottis
Space (air) below the vocal folds (air in the trachea)
Subglottis
T/F: The extra-cellular matrix (ECM) of vocal fold tissue consists of elastin, collagen, proteoglycans, hyalouronic acid, etc. These materials are important to reduce the scarring of the tissue and also improve the biomechanical properties of vocal fold motion.
True
Muscles that attach WITHIN the larynx
Intrinsic laryngeal muscles
Muscles that attach to the larynx via some point OUTSIDE the larynx; helps with stability
Extrinsic laryngeal muscles
Muscles that act (functionally) to move the vocal folds closer together to close the airway
Adductors
