adj. resembling a pyramid in shape; specifically, relating to the pyramidal tract in the brainstem. Often used in anatomical contexts to describe structures with a triangular or conical profile.
The doctor examined the pyramidal tract in the patient's brain.
The pyramidal cells in the cerebral cortex are responsible for sending signals to the spinal cord to control voluntary muscle movement.
Damage to the pyramidal system often results in a loss of fine motor control, as the signals that normally travel from the brain to the muscles are interrupted or delayed.
From Medieval Latin pȳramidālis.
