Facial motor nucleus

By contrast, a lower motor neuron lesion to the facial motor nucleus results in paralysis of facial muscles on the same side of the injury. If a cause, such as trauma or infection, cannot be identified (this situation is called idiopathic palsy) this condition is known as Bell's palsy. Otherwise it is described by its cause.

Is this statement correct "is bell palsy a lower motor neuron lesion"?
yes
