Speech Systems Larynx anatomy and functions

Quiz yourself by thinking what should be in each of the black spaces below before clicking on it to display the answer.
        Help!  

Question
Answer
Larynx is made of...   show
🗑
Biological Functions of Larynx   show
🗑
show attached to thyroid cartilage, does not function for phonation, highly important for swallowing  
🗑
show attachment for many muscles, superior and inferior cornu, notch,  
🗑
Cricoid Cartilage   show
🗑
show 2 pyramid-like structures at top of cricoid cartilage. Muscular process and vocal processes, attach to muscles (outside) and vocal folds (inside). Many degrees of freedom.  
🗑
Cricothyroid Joint   show
🗑
show only bone in body that does not articulate to another bone, helps connect tongue base to larynx, supports larynx in neck  
🗑
Cavities of Larynx   show
🗑
show textbook anatomy point, entry from larynx to pharynx  
🗑
show space between aditus and false vocal folds  
🗑
Valleculae   show
🗑
show Space between aryepiglottic fold and thyroid cartilage  
🗑
Glottis   show
🗑
show just superior to true VF, not meant to vibrate, help create the 3-D space of larynx.  
🗑
show attach to cricoid and thyroid cartliages  
🗑
Extrinsic Muscles of Larynx (Elevators)   show
🗑
Extrinsic Muscles of Larynx (Depressors)   show
🗑
show 1 pt of attachment in larynx, 1 point of attachment outside larynx, support larynx in cavity, but also helps move larynx as a whole system  
🗑
Intrinsic Muslces   show
🗑
Superior Laryngeal Nerve (SLN)   show
🗑
RLN (Recurrent Laryngeal Nerve)   show
🗑
Adductor Muscles   show
🗑
Abductor Muscles   show
🗑
Tensor Muscles   show
🗑
Relaxer Muscles   show
🗑
True Vocal Folds   show
🗑
6 degrees of Arytenoid Cartilages   show
🗑
show False Vocal Folds, made of aryepiglottic folds  
🗑
show Superficial (main vibrating portion, very flexible), Intermediate (allows anterior to posterior stretch, more dense), Deep (collagen fibers, very dense, protect VF from overstretching)  
🗑
show ligament that goes from arytenoids to thyroid cartilages. Most innermediate ligament  
🗑
show Visual representation of the acoustic signal. Time (horiz axis in millisecs), Frequency (vertical axis in Hz), Intensity (darkness)  
🗑
Fundamental Frequency   show
🗑
Optimal Pitch vs Habitual Pitch   show
🗑
show Sound Pressure Level: measured in dB. Reflects acoustic power of signal. Based on ability to build up subglottic pressure.  
🗑
show Voice Range Profile: gives a Phonetogram: comprehensive data about frequency a person can produce.  
🗑
MPT:   show
🗑
S:Z Ratio   show
🗑
VHI   show
🗑
CAPE-V   show
🗑
GRBAS   show
🗑
show halogen light source tube through nasal cavity for a birds-eye view of larynx  
🗑
show Same as Nasendoscopy but with a strobe light to see VF movement  
🗑
show measuring how much VF make contact with each other. Often done with Nasendoscopy.  
🗑
MAT   show
🗑
show FITS INTO MAT. Negative pressure caused by the narrow formation of larynx causes VF to be pulled together again. Because of the increase of velocity of airflow, pressure becomes negative, so the VF come back together.  
🗑
show Cough, Throat clearing, grunt  
🗑
show Simultaneous attack (breath during attack), Breathy attack (breath comes before stop), Glottal Attack (attack prior to airflow)  
🗑
show Pattern of activity vocal folds undergo during vibration  
🗑
show Optimal, habitual register  
🗑
show Glottal Fry, low rough, not much airflow, decreased tension of VF  
🗑
show Falsetto, VF lengthen to thin and reed-like, Vocal ligament is doing most of the vibrating  
🗑
Whistle   show
🗑
