Document Summary

Motor speech disorders: difficulty in coordinating your messages: motor coordination can be difficult: act of brain telling speech system parts what to do. Motor speech disorder: speech production deficit resulting from a problem in speech motor control, deficit in speech, not language, other oral movements (eating, facial emotion) can co-occur. Systems involving speech: central and peripheral nervous system, knock out = motor speech disorder, central: brain, brain stem, spinal cord, peripheral: cranial nerves, spinal nerves, respiratory system, phonatory system, articulatory system, resonatory system. Speech motor control: muscles must coordinate, breathing, voicing, appropriate (cid:862)shu(cid:374)ti(cid:374)g(cid:863) of sou(cid:374)d, coordination of the articulators.
