Document Summary
What are motor speech disorders: difficulties related to problems of movement resulting from neurological disorder or injury, neurological impairments affecting speech production. Execution of movement patterns: children and adults are affected. Structures of the brain important for motor speech function: complex network of structures and pathways, frontal lobes house the primary motor cortex. Descending pathways originate from primary motor cortex. Modulate the activity of the primary motor cortex damage: Will either result in reduced and/or slowed movements or in abnormal, involuntary movements: the cerebellum and its connections coordinate the control of fine motor activities. Maintain muscles tone participate in motor learning the motor speech production process: movement plan/program: retrieved from memory, plan: set to motor control areas, transmitted: With precise timing along the nerves to muscles and structures of the speech mechanism resulting in sequences of acoustic signals that are recognized as speech sounds: nerve impulses:
