Motor system: organisation and disorders This note deals with how motor responses are controlled by the nervous system The motor system: UMNs and LMNs Motor system: This consist of neurones & pathways whose integrated activity allows normal movements to occur. There are 5 main areas of CNS involved in motor control and they all participate in sequence of events that occurs when voluntary movement is desired: o Pyramidal system, origins in the cortex o Basal ganglia o Cerebellum o Brainstem o Lower motor neurones (spinal cord & brainstem) Upper motor neurones (UMNs) Muscle reflexes & reflex arcs form basic plan by which movement can occur Central pattern generators in spinal cord co-ordinate basic programmed rhythmic movements These plans modified by UMNs originating in cerebral cortex & brainstem UMNs project to spinal cord via descending tracts where they exert influence on spinal LMNs in reflex arcs Tracts are split into two groups o

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.
