WebDec 10, 2024 · How do neurofibrils differ from nerve fibers? ANSWER : Neurofibrils are cytoskeletal intermediate filaments maintaining cell shape, but they do not conduct impulses. Which is the main receptive portion of the neuron? ANSWER : the dendrite Many neurons have many short, branching extensions called dendrites. WebThese neurons are pseudounipolar and contain an axon-like process that bifurcates with one branch extending toward the periphery and the other branch heading toward the grey matter of the spinal cord. Fibers heading toward the periphery leave the ganglion through the spinal nerve, where they run together with motor fibers.
