See the answer I highlighted.

By the way, why you raised this question? What's the clinical importance in step 2 CK?


Four basic mechanisms are linked to the production of tremor. It is likely that combinations of these mechanisms produce tremor in different diseases. Mechanical oscillations of the limb can occur at a particular joint; this mechanism applies in cases of physiologic tremor. Reflex oscillation is elicited by afferent muscle spindle pathways and is responsible for stronger tremors by synchronization. This mechanism is a possible cause of tremor in hyperthyroidism or other toxic states. Central oscillators are groups of cells in the central nervous system present in the thalamus, basal ganglia, and inferior olive. These cells have the capacity to fire repetitively and produce tremor. Parkinsonian tremor might originate in the basal ganglia, and essential tremor might originate within the inferior olive and thalamus. Abnormal functioning of the cerebellum can produce tremor. Positron emission tomography studies have shown cerebellar activation in almost all forms of tremor.
