The pyramidal tract, specifically the corticospinal tract which is part of the pyramidal system, is primarily responsible for the control of fine, discrete movements of the extremities. This pathway originates in the motor cortex and travels down the spinal cord to synapse directly onto motor neurons or interneurons in the spinal cord, allowing for precise voluntary movement control.
