## Definition

shaped like a pyramid, with a wide base and a pointed top. In medicine, it describes a specific part of the brain that helps control movement.

For teachers: 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.

## Examples

- 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.
