Final answer:
The corticospinal system is often referred to as the corticospinal tract. This tract connects the cerebral cortex to the spinal cord and is responsible for generating voluntary movements and controlling muscle contractions.
Step-by-step explanation:
The corticospinal system is often referred to as the corticospinal tract. This tract is a major descending pathway in the central nervous system that connects the cerebral cortex to the spinal cord. It is responsible for generating voluntary movements and controlling muscle contractions. The corticospinal tract is composed of two neurons, the upper motor neuron and the lower motor neuron, which work together to transmit signals from the brain to the muscles.
