Where are the cell bodies for the UMN of the corticonuclear system?
Precentral gyrus – laterally in association with the face area of the humunculus
relative position of the motor nuclei for CN III
Superior Colliculus
relative position of the motor nuclei for CN IV
Inferior Colliculus
relative position of the motor nuclei for CN V
Upper pons
relative position of the motor nuclei for CN VI
Lower pons
relative position of the motor nuclei for CN VII
Lower pons
relative position of the motor nuclei for CN IX & X
Open medulla
relative position of the motor nuclei for CN XI & XII
Closed medulla
identify which are UMN cranial nerves innervated contralaterally
VII [(facial--Lower part of face (buccinator etc)]

XI [spinal accessory--traps is contralateral, SCM is ipsilateral)
identify which are UMN cranial nerves innervated bilateraly
III-oculomotor
IV-trochlear
V-trigeminal
VI-abducens
VII-facial (upper part-obicularis oculi)
IX-glossopharyngeal
X-Vagus
XII - hypoglossal
Describe clinical symptoms likely for individuals with lesions in Midbrain, in the right side, at the level of the superior colliculus.
III –Right sided (ipsilateral ptosis) inferior lateral look, dialated pupil, lack of accomidation, double vision
Describe clinical symptoms likely for individuals with lesions in Upper pons, on the left side.
IV – right sided (contralateral) extortion and difficulty looking medially and down, double vision
Describe clinical symptoms likely for individuals with lesions in Lower pons, on the right side.
VI – Right sided (ipsilateral) adduction of eye and double vision
Describe clinical symptoms likely for individuals with lesions in Open medulla, on the left side.
IX & X – Vagus LMN. Hoarseness due to loss of ipsilateral motor nerves to larynx. Difficulty in swallowing. Note, because of loss of levator veli palitini M., uvula will bend towards unaffected side.
Describe clinical symptoms likely for individuals with lesions in Closed medulla (just at the juncture of the open medulla), on the right side.
XII - Deviation
of tongue to affected (Right) side
Location and function of Edinger-Westphal nucleus
III – superior colliculus

Parasympathetics to the eye
Location and function of Superior salivatory nucleus
VII – Pontomedullary junction

parasympathetic supply to the submandibular ganglion
Location and function of Inferior salivatory nucleus
IX – Open Medulla

Parasympathetic to parotid gland
Location and function of Dorsal motor nucleus of the vagus
X – Open Medulla

responsible for all vagal preganglionic parasympathetic axons, from the neck region all the way to the midgut
