|
Role of articulation and resonance in speech |
-modifying vocal sounds -changing the the shape of a sound wave, which takes place in the resonatory cavity -generating sounds themselves |
|
|
Vocal tract consists of these three cavities |
-all are located above the vocal folds -oral cavity, nasal cavity, and pharyngeal cavity |
|
|
Articulation definition |
Process of joining two elements together to shape speech sounds |
|
|
Articulators for speech are.... |
-System of mobile and immobile articulators brought into contact for the purpose of shaping sounds for speech |
|
|
Because of its location, sounds always travel through the..... |
Pharyngeal cavity |
|
|
Moveable articulators |
-tongue -mandible -lips -soft palate (velum) -pharyngeal walls -larynx |
|
|
Fixed articulators |
-upper incisors -alveolar ridge -hard palate |
|
|
Main purpose of facial skeleton |
Speech, airflow, and facial expressions |
|
|
Main function of cranial skeleton |
Houses and protects the brain |
|
|
Mandible |
-Unpaired, movable -posterior portion= condylar process -anterior portion= Coronoid process -Mandibular notch at top, Ramus as body, angle anteriorly and body near frontal part |
|
|
Mental spine of mandible |
-has 2 ridges -starting point for geniohyoid muscle -place for blood vessels and nerves to travel through |
|
|
Mandible’s role in speech |
-associated with tongue and lower lip positioning -innervated by cranial nerve 5 |
|
|
Maxillae |
-left and right sides are sutured (articulated) together -paired -mid face (cheek area), connects with frontal bone, nasal bone, and zygomatic bone |
|
|
Maxillae |
-left and right sides are sutured (articulated) together -paired -mid face (cheek area), connects with frontal bone, nasal bone, and zygomatic bone |
|
|
Significance of palatine process |
-considered part of the maxilla bone -makes up 2/3 to 3/4 of the hard palate |
|
|
Parts of the nasal septum |
-vomer -septal cartilage -perpendicular plate of ethmoid PAIRED NASAL BONES ARE NOT PART OF THIS |
|
|
Nasal bones |
Make up the bridge of the nose lateral to the frontal process of the maxillary bone |
|
|
Vomer |
-Articulates with the palatine process and palatine bone and maxilla -Midlines are considered to be the intermaxillary suture and the interpalatine suture |
|
|
Vomer |
-Articulates with the palatine process and palatine bone and maxilla -Midlines are considered to be the intermaxillary suture and the interpalatine suture |
|
|
Inferior nasal conchae (inner turbinate bones) |
-scrolls of bone medially from palatine and maxillary bone -only independent bone of the ethmoid -humidifies air |
|
|
Zygomatic bones |
-Zygomatic arch -orbital process -maxillary process -temporal process |
|
|
2 components of zygomatic arch |
Temporal process of zygomatic bone and the zygomatic process of temporal bone |
|
|
Ethmoid bone contains: |
-Crista galli -perpendicular plate -middle and superior nasal conchae -cribiform plate |
|
|
Sphenoid bone |
-shaped like a butterfly -has greater and lesser wing, corpus, lateral plate, medial plate, and hamulus -important for swallowing |
|
|
Parietal bone |
-paired -large, square shaped -has connections to frontal, occipital, and temporal bones |
