Upper motor neurons and lower motor neurons act to carry nerve impulses from the brain out to the muscles in the body. Upper motor neurons supply input to the lower motor neurons. They do this by either synapsing directly to lower motor neurons‚ or by synapsing with a local circuit neuron‚ which then synapses with a lower motor neuron. The upper motor neurons originate in the motor region of the cerebral cortex or brainstem. The neurons from the cerebral cortex are important for planning‚ initiating

Ward-Leonard Motor Generation System Introduction: A control system generally controls‚ regulates‚ and updates its output continuously based on present inputs‚ nature of the system‚ and the past outputs. In other words‚ there is a feedback mechanism that is inherent in the system‚ and is called a closed loop control system. For example‚ adding an emitter resistance to a common emitter amplifier‚ results in a negative feedback mechanism in the amplifier system – if the output current increases
