What is Quiet Breathing?
When the pressure inside and outside of the lungs is the same.
External Intercostals
Group of muscles that raise the ribs UP and OUT to increase the diameter of the TC.
Internal Intercostals
Pull DOWN ribs to decrease the TC.
Pull the ribs DOWN and APART to decrease the diameter of the TC.
-Thick dome-shaped muscle.
-Chief muscle of inhalation.
-Just below the lungs, separates the abdomen from the TC.
-Provides openings for the esophagus and aorta to pass through.
Starting point of lower airway, just below the larynx
Tube like structure in neck that includes various muscles along with vocal folds, cartilages, and membranes
Muscles of Larynx
Extrinsic and Intrinsic
Extrinsic Muscles
-One attachment to structures outside the larynx and one inside.
-Provides supportive framework for larynx.
Intrinsic Muscles
-Both attachment confined within the larynx.
-Play a leading role in phonation
Bernoulli Effect
When gases or liquids move through a constructed passage, velocity increases and pressure decreases
Process by which the voiced breath stream (which is produced by VFs) is modified to enhance and dampen certain frequency components
1. Pharyngeal Cavity
2. Oral Cavity
3. Nasal Cavity
Pharyngeal Cavity
-Part of upper airway
-located superiorly and posteriorly to larynx
-base of tongue
-attached to pharynx.
Oral Cavity
-Resonating structure for all sounds except for /m,n, ng/
-Velum should be elevated in order to make contact with posterior pharyngeal wall. Separating the nasal cavity from pharynx and oral cavity
Nasal Cavity
Man->more nasalized quality
Fully nasalized sounds are /m,n,ng/
-Velum is lowered in order to produce nasal sounds
Molding of the air stream into recognizable speech sounds by several structures (articulators) in the mouth.
Moveable Articulators
1. Tongue
2. Lip
3. Velum/Soft Palate
4. Jaw/Mandible
Tongue (MVP)
What are the parts of the tongue?
1. Tip
2. Blade
3. Dorsum
4. Root
thinnest part, rests behind front teethe
next, after the tip
- below alveolar ridge
largest part, makes contact with both hard and soft palate
very back lower portion of tongue attached to pharynx
-Made primarily of the obicularis oris
-/p,b,m/-play an important role in bilabials and labiodentals /f,v/
Velum/Soft Palate
Begins at end of hard palate and extends towards the pharynx
Velar Muscles
-Levator veli palatini
-Tensor veli palatini
Levator veli palatini
Elevates Velum
Tensor veli palatini
Stretches/Tenses Velum
Elevates Velum and elevates the dorsum tongue
Lowers velum, moves pharyngeal walls inward
Muscles in the uvula
-Facilitator of articulation and resonance
-Forms the floor of the mouth and houses the lower teethe.
-Increases or decreases the size of the oral cavity
Immovable Articulators
1. Teethe
2. Hard Palate
3. Aveolar Ridge
-Directly involved in articulation of /f,v, th (voice and voiceless)/.
-Help produce the friction quality in many fricative sounds.
-Lower incisors, as breath stream passes over the incisors edges.
Hard Palate
Boney structure separating the oral cavity from the nasal cavity, it forms the floor of the nose and the roof of the mouth.
Aveolar Ridge
Part right behind upper teethe.
Place of lingual contact for several front sounds including /t,d,s,z,n,l/.
