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) rubrospinal tracts
B) spinal cord
C) primary motor cortex
D) premotor cortex

Question

Quizplus · Accepted Answer

The premotor cortex is responsible for planning and coordinating skilled movements, such as playing the piano. Damage to this area would result in the loss of ability to perform such activities without paralysis or weakness in specific muscles. The rubrospinal tracts are involved in controlling fine and skilled movements, but damage to them would result in weakness or paralysis of specific muscles. Damage to the spinal cord may result in various motor impairments depending on the location and severity of the damage. The primary motor cortex is involved in initiating and controlling voluntary movements, but damage to it would not necessarily result in the loss of ability to perform skilled motor activities.
