Point 15 Intro Pathway Deficit Note Overview Problems Contents Anatomy

You should remember that the inferior salivatory lies medial to NUCLEUS AMBIGUUS in the medulla. A lesion involving this nucleus will result in the loss of salivation from the ipsilateral parotid gland. In contrast, the superior salivatory and lacrimal nuclei lie medial to MOTOR VII. For our PROBLEM SOLVING, any lesion that includes motor VII, AND THE REGION IMMEDIATELY MEDIAL TO IT will result in motor VII problems PLUS a lack of saliva secretion from the ipsilateral submandibular and sublingual glands, and the loss of tearing from the ipsilateral lacrimal gland.
