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.
In the corneal reflex, the ophthalmic nerve acts as the afferent limb â detecting the stimuli. The facial nerve is the efferent limb, causing contraction of the orbicularis oculi muscle. If the corneal reflex is absent, it is a sign of damage to the trigeminal/ophthalmic nerve, or the facial nerve.
