Phrase: corticospinal tract | Statement: [primary motor cortex, projectsTo, corticospinal tract]

Target entity: corticospinal tract
Context triple: [primary motor cortex, projectsTo, corticospinal tract]

• A. arcuate fasciculus
  The arcuate fasciculus is a major white matter tract in the brain that links language comprehension and production regions, playing a key role in speech and language processing.
• B. primary motor cortex
  The primary motor cortex is a brain region in the frontal lobe responsible for the voluntary control and precise execution of skeletal muscle movements.
• C. supplementary motor area
  The supplementary motor area is a region of the medial frontal cortex involved in planning, coordinating, and initiating complex voluntary movements, especially those requiring sequences or bilateral coordination.
• D. CNS
  CNS is the IATA airport code for Cairns Airport, the main international and domestic gateway to the Cairns region in Queensland, Australia.
• E. premotor cortex
  The premotor cortex is a region of the frontal lobe involved in planning and preparing voluntary movements, integrating sensory information to guide motor actions.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Entity: corticospinal tract
Triple: [primary motor cortex, projectsTo, corticospinal tract]

The corticospinal tract is a major descending motor pathway that carries voluntary movement commands from the cerebral cortex to motor neurons in the spinal cord.
