Walking movement has an automatic motor function performed by three main control systems in brain stem. Voluntary movement is baused by the pathway from the cerebral cortex (motor area) to the spinal cord (anterior gray horn) inputting the motor neuron cell body which is the final common path to the muscle. The motor area is governed by the cerebelum and basal ganglia. Its output is controlled by feed back systems from the sensory area. Acetylcholine (neuro-muscular junction), Ca^<2+>(endoplasmic retriculum) and ATP (hydrolysis by ATPase) play an important role as chemical mediaters for muscle contraction. The dysfunction of each in any level of the motor control system causes motor disorder such as motor neuron disease, myasthenia gravis (acethylcholine receptor), progressive muscular dystrophy and Parkinson's disease (dopamine neuron in basal ganglia).}, pages = {173--184}, title = {Movement skill and its disorder}, volume = {10}, year = {2001}, yomi = {ヤマモト, タカノブ and ヤマモト, タカノブ} }
