Corticobulbar tract
Corticobulbar Tract
The Corticobulbar Tract (pronunciation: kor-ti-ko-bul-bar trakt) is a component of the Central Nervous System that connects the Cerebral Cortex to the Brainstem. This tract is significant in the control of voluntary movements, particularly those of the face, head, and neck.
Etymology
The term "Corticobulbar" is derived from two words: "Cortico" which refers to the cerebral cortex, and "bulbar" which is related to the brainstem or medulla oblongata, often referred to as the bulb.
Function
The Corticobulbar Tract is responsible for carrying motor fibers from the cerebral cortex to the brainstem. These fibers are crucial for voluntary movements, especially those involving the muscles of the face, head, and neck. The tract also plays a role in the control of eye movements, swallowing, and speech.
