Document Summary
Anatomy & physiology of speech & swallowing ii. Modulation of the airstream using articulators (i. e. tongue, lips, jaw, and velum) Amplification of specific range of frequencies of sound using resonating cavities (i. e. pharynx, oral cavity, and nasal cavity) Temporal bone (lower side, just above mandible and ear canal) Sphenoid bone (right where the temple is, rest of bone is on the inside of the skull) Movable articulators (lips, tongue, mandible, pharynx, and velum (another name for soft palate)) Articulators permit filtering or shaping of sound generated at larynx. May 10th, 2016: place of articulation (consonants, vowels, manner of articulation (occlusion, frication, resonance (cavity shapes, velum up/down) Velum hangs into oropharynx (back of mouth) when relaxed. Velum capable of being elevated, lowered, and tensed. Consists of 4 major body parts: body (horizontal segment; location of teeth, ramus (vertical segment, angle ( curve of jaw , condyle (hinges jaw to skull; forms part of temporomandibular joint)
