Swelling of vocal folds, due to an infection Viral infection (a “cold” of the upper respiratory track) is most common cause Described as hoarseness
What is Laryngitis
100
explain to client Voiceless vs. Voiced
What is place hand on throat and feel vibration
100
-only muscle that opens vocal folds. looks like a hairline parted in the middle
What is POSTERIOR CRICOARYTNOID
100
explain increase in pitch
What is cricorthyroid muscle contracts, pulls thyroid forward and down, causing VFs to lengthen and pitch to increase.
100
we don’t hear frequency, we hear
What is pitch
200
Most common vocal fold lesion found in teenagers Caused by voice misuse or overuse Caused by trauma or injury to the vocal folds Benign non-cancerous growths Always bilateral because of contact
What is Vocal Nodules
200
vowels that aren’t stressed (laxed vowels in phonation exercises then build and add others in) muscle relaxation - laryngeal massage, lax vowels for less strain
What is treatment of hyperfunction
200
5 layers of vocal folds
What is 1.epithelium: squamos 2.superficial layer:random fiber movement/fibrous & elastin to cushion 3.intermediate layer: elastin fibers 4.deep layer: collagen fibers 5.Thyroaretnoid: muscle fibers
200
explain decrease in pitch
What is thyroaretnoids attach to vocal ligaments. moves arytenoids forward & down, shortens VF, decreases pitch
200
attached to vocal ligament and different layers of vf most important muscle for phonation and speech Adductor Tensor Antagonistic to Cricothyroid
What is Thyroarytenoid
300
Caused by misuse, overuse, or trauma to the vocal folds (usually one big misuse and the fold popped) Frequently require surgical removal after non-surgical treatment options (i.e., speech therapy, medication) have failed. Very rare to have bilateral but there will be contact redness/soreness
What is Polyps
300
increase support
What is treatment of hypofunction
300
layers 2-4
What is lamina propria. 2.superficial layer 3.intermediate layer 4.deep layer
300
Size and mass - frequency factors related to VF
What is Size – Larger = lower fundamental frequency Mass - Thinner = higher fundamental frequency
300
Pars recta - erect, right in front, vertical Pars oblique - lateral to thryoid Main tensor of VFs most responsible for falsetto
What is Cricothyroid
400
starts as GERD then acid spills through esophageal sphincter into larynx
What is LPR
400
breathing passage so our lungs can fill with air and sustain life. Afterthought = vocalization
What is primary function of larynx
400
thyroaretnoid
What is vocal ligament (body)
400
Open and close motion represents one cycle Measured in Hertz (number of vibrations per second)
What is A cycle of vibration:
400
Two sets of muscle fibers: one paired one unpaired Oblique interarytenoids Transverse interarytenoids
What is Interarytenoids
500
more common thing to treat in voice therapy. raise head of bed, exercise, diet
What is GERD
500
ability to close off airway (capture air) to build up pressure to lift items Capture air within the thorax (stabilizes) For support in lifting, pushing, pulling, etc.
What is Abdominal fixation
500
1/3 size and more narrow at birth Narrower structures and areas: Epiglottis Subglottis Glottis oral and laryngeal cavities sit closely to make for safer swallowing
What is child larynx
500
Base frequency of vibration (mass and tension) F0 depends on individual
What is Fundamental frequency (F0):
500
overlap and bring arytenoids together
What is oblique and transverse interarytenoid
