Cuando las fibras corticonucleares pasan por la protuberancia basilar, sus ramos  adoptan una dirección dorsal hacia la calota para terminar en el área de los núcleos motores de los nervios trigéminos y facial
Las que se dirigen a los núcleos  motores del trigémino  finalizan en las interneuronas adyacentes a ellos.El sistema corticonuclear  envía casi el mismo número  de fibras  hacia los núcleos del lado derecho e izquierdo. Algo semejante sucede con los núcleos izquierdo y derecho del nervio facial.
Mientras que los músculos de la expresión facial de la mitad superior de la cara están controlados de forma equilibrada  por ambos hemisferios, los músculos de la mitad inferior de la cara se encuentran bajo la influencia  primordial  del hemisferio contralateral.
Por consiguiente , una lesión de las fibras corticonucleares rostral al núcleo motor del nervio fácial provoca un descenso de los músculos de la comisura de la boca y de la porción inferior de la cara en el lado opuesto de la lesión. Este defecto se denomina parálisis facial central.
Por el contrario ,una lesión de la raíz del nervio facial originará una parálisis flácida  de los músculos faciales de las porciones superior e inferior de la cara en el lado ipsilateral.Este trastorno se denomina parálisis facial de Bell.
