Document Summary
Anatomy: the study of structures of the body and the relationship of these structures to one another. Physiology: how structures work together to result in function. Complements anatomy by describing how and what anatomical structures do. Breathing delivers fresh air to the lungs, exchanging oxygen for carbon dioxide. Rib cage: bony structure that supports and protects the passageways and lungs. Phonation: is the production of sound via vibration of the vocal fold in the larynx. Attach to thyroid cartilage (front) and arytenoids (back) Arytenoids help move vocal folds from closed to open. The vocal folds vibrate as a result of air flow from the lungs. The amplification and modification of sound by vocal tract cavities. Gives voice its unique sound: pharynx, oral cavity, nasal cavity. Vocal tract: acoustic tube that shapes sound energy produced by respiratory and laryngeal systems into speech sounds. Articulation: the shaping and production of speech sounds as a result of movement of the articulators.
