Document Summary
Ling 1p93 chapter 12 notes: motor speech disorders. Motor speech disorder: an impairment of speech production caused by defects of the neuromuscular system, the motor control system, or both. Respiratory system: pulmonary mechanism is a major structure which regulates the inhalation-exhalation cycle for passive breathing and for producing speech. Phonatory system: regulates the production of voice and the prosodic, intonational, aspects of speech. Resonatory system: regulates the resonation or vibration of the airflow as it moves from the pharynx into the oral or nasal cavities. Articulatory system: regulates the control of the articulators within the oral cavity to manipulate the outgoing airflow in different ways, usually at very high speeds. Intrinsic muscles: originate within the tongue and regulate fine tuned movements. Extrinsic muscles: originate outside the tongue and control coarser movements. Speech motor control: individuals control over the muscular coordination involved with producing speech.
