Two types of motor neurons contained by the central nervous system - Answer 1. Upper motor neuron (UMN) -cerebrum 2. Lower motor neuron (LMN) -brainstem and spinal cord What is the pyramidal system? - Answer -The system responsible for controlling voluntary motor movements (fine controlled, skilled, rapid, etc) -Direct activation pathway, direct motor system -Has only one axonal synapse Two major motor pathways within the pyramidal system - Answer 1. Spinal motor pathway 2. Bulbar m...
