Loss of ability to perform skilled motor activities such as piano playing,with no paralysis or weakness in specific muscles,might suggest damage to the _ .
A)spinal cord
B)primary motor cortex
C)premotor cortex
D)rubrospinal tracts

Question

Quizplus · Accepted Answer

The premotor cortex is responsible for the planning and execution of skilled motor activities, such as playing the piano. Damage to the premotor cortex could result in a loss of ability to perform these activities without paralysis or weakness in specific muscles. The spinal cord and rubrospinal tracts are more involved in the transmission of signals between the brain and muscles, and damage to the primary motor cortex would likely result in weakness or paralysis in specific muscles rather than a loss of skilled motor activity.
