Term
|
Definition

|
|
Term
|
Definition
| Located on the sides of the oropharynx |

|
|
Term
| Source-Filter Theory of Vowel Production |
|
Definition
| States that voicing source is generated by vocal folds and routed through vocal tract where it is shaped into a variety of vowel sounds by the shape and configuration of tongue, mandible, soft palate, and other articulators |

|
Term
|
Definition
| Where cleft lip can occur |
|
|
Term
|
Definition
| May involve soft tissue alone, or include cleft of maxilla up to incisive foramen; unilateral or bilateral; appears to result from failure of embryonic facial and labial tissue to fuse during development |
|
|
Term
|
Definition
| May involve both hard and soft palates; If something blocks movement of tongue (micrognathia), palatine processes will not move in time to make contact |
