Redox 8 Oxidation Number Method (Oxidation State Method) another method when you do not divide into half reactions Charge and mass both must be balanced 1. Determine oxidation number of atoms to see which ones are changing 2. Put in coefficients so no net change in oxidation number 3.
Previous Chapter: Next Chapter: The corneal reflex is usually tested after the pupils, but the cranial nerves involved are out of order. The afferent arc is mediated by the nasociliary branch of the ophthalmic branch (Vi) of the trigeminal or 5th cranial nerve, and the efferent arc is the seventh (facial) nerve.
Quick Answer. The corneal reflex is an involuntary closing of the eyelids when the cornea is touched by a foreign object. The function of this reflex is to protect the eye from damage. Absence of a corneal reflex may indicate damage to the fifth and seventh cranial nerves, which mediate the reflex.
