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

Question

Quizplus · Accepted Answer

The premotor cortex is responsible for planning and coordinating skilled movements, and damage to this area could result in a loss of ability to perform those activities even if there is no paralysis or weakness in specific muscles. The other options listed (rubrospinal tracts, spinal cord, and primary motor cortex) are also involved in motor control, but would not specifically cause a loss of skilled movements without accompanying muscle weakness or paralysis.
