Question

Damage to the Supplementary Motor Area can impair a patient’s capacity
for volitional movement.
a) How would you elicit evidence of such impairment?
b) Describe the conditions that typically do NOT impair voluntary movements in
the same patient?

Answer 1

The supplementary motor area in the form of the primary cerebral cortex that is contributed to the control of movement. This is located on the midline surface of the hemisphere in front of the primary motor cortex. This occupied the posterior part of the superior frontal gyrus which is responsible to plan the complex of any organism. This is situated medially and involved in the planning of complex movement.
a.Damage to the supplementary motor area which leads to cause impairment of patient capacity for the volitional movement as the kind of supplementary motor area damage. This kind of damage will lead to cause stroke or loss of motor control. In different cases, the hand movement is observed in response to stimuli that are observed in the chronic stage. Due to this, the cognitive process leads to the initiation of the revolutionary movement and this may lead to cause stroke.
b.The conditions which are not responsible for impaired voluntary movement in the patient are due to the jerky movement and suppression of voluntary movement. Nerve damage generally arises due to a certain kind of disease which affect the alpha motor neurons and upper motor neuron.
