The tongue licks the wound is a reminder that when the hypoglossal nerve (CNXII) is damaged, the tongue deviates to the same side of a lesion to the cranial nerve. (eg, if the tongue deviates to the right, the right side of CNXII is damaged)
LMN Lesion of the hypoglossal nerve producing tongue deviation to the side of the lesion
hypoglossal nerve lesion is TONGUE TOWARDS!! - but the upper motor fibers in the corticobulbar tract are different, if these have a lesion, the tongue goes away!
