Q8. Observe the involuntary and voluntary movements that happens in your day-to-day life. Write 5 each.
INVOLUNTARY VOLUNTARY
Answers
Answer:
luntary movements: The final motor commands for movements are mediated by several descending motor pathways. These final pathways are modified, regulated by two main loops (basal ganglia loop and cerebellar loop).
Involuntary movements (medical term): The involuntary movements are produced by a non-intentional, pathological activation anywhere within the final common pathways or the above two loops. I would like to personally divide those into four major groups.
Tremor: Some oscillation mechanisms may produce tremor: one site oscillation or loop oscillation.
Myoclonus: Sudden, brief, shock-like involuntary movements arising from anywhere from the cortex to the muscle.
Chorea/ballism: Suddenly appearing, irregular, phasic movements which are usually mimicked by normal subjects.
Dystonia/athetosis: Sustained, long duration muscle contraction sometimes associated with torsion components.
