Corticobulbar tract

The corticobulbar tract is a pathway in the brain that carries signals from the cerebral cortex to the brainstem. It plays a crucial role in controlling facial and neck muscles, facilitating actions like chewing, swallowing, and making facial expressions. This tract sends commands to cranial nerves, which directly innervate the muscles in the head and neck. Damage to the corticobulbar tract can lead to difficulties with these functions, highlighting its importance in everyday tasks involving facial movement and coordination.
