pyramidal tract

A bundle of nerve fibers that carries motor signals from the cerebral cortex to the spinal cord to control voluntary muscle movement.
Noun
pl: pyramidal tracts

This term is a specialized anatomical designation used primarily in neurology and medical contexts. It refers to the primary descending motor pathway, characterized by the decussation (crossing over) of fibers in the medulla oblongata, which explains why one side of the brain controls the opposite side of the body.

Because it describes a specific biological structure, the term is used in a technical register. It is rarely used in general conversation and is typically found in clinical reports, textbooks, or academic discussions regarding motor neuron diseases or spinal cord injuries.
