Alfa motorneuron
WebMotorneuron geeft signaal om te relaxeren. Wat houdt recurrente inhibitie in? Agonisten (spieren met dezelfde functie) & synergisten ( groepen spieren die samenwerken) worden geïnhibeerd. Dit gebeurt door de recurrente collaterale tak van het alfa-motorneuron naar de inhiberende interneuronen (=renshaw cells). eerder voor fijne motoriek Upper motor neurons originate in the motor cortex located in the precentral gyrus. The cells that make up the primary motor cortex are Betz cells, which are giant pyramidal cells. The axons of these cells descend from the cortex to form the corticospinal tract. Corticomotorneurons project from the primary cortex directly onto motor neurons in the ventral horn of the spinal cord. Their axons synapse on the spinal motor neurons of multiple muscles as well as on spinal interneurons. …
