Question

After Joe has a stroke, his doctor asks joe to touch his right pointer finger to his chain-but joe is unable to move his right hand. However, when the doctor stimulates Joe's pointer finger with a painful stimulus, Joe's muscles quickly move this and away from the stimulus. The doctor concludes that?

A) the stroke caused damage to Joe’s frontal eye field which interfered with his effort to touch his chin
B) The stroke caused damage to Joe’s right primary motor cortex
C) The stroke caused damage to choose right premotor cortex
D) based on the doctors observations, and none of the listed answers are correct conclusions

Answer 1

D) based on the doctors observations, and none of the listed answers are correct conclusions

Step-by-step explanation:

B) The stroke caused damage to Joe’s right primary motor cortex❌

It's doesn't has to do with the primary motor cortex. The primary motor cortex of the brain majorly control the voluntary skeletal muscle processes through contralateral innervation.

C) The stroke caused damage to choose right premotor cortex❌

It's doesn't has to do with the primary motor cortex. The premotor cortex of the brain controls which voluntary skeletal muscle groups will be favored and promoted and the mode of usage before the stimulation of the primary motor cortex.

However, none of these answers are correct.✔

The options are well proved incorrect when the central nervous system control of voluntary skeletal muscle contractions is compared against the reflex arc activation.
