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.
Most reflex arcs involve only three neurons. The stimulus, such as a needle stick, stimulates the pain receptors of the skin, which initiate an impulse in a sensory neuron. This travels to the spinal cord where it passes, by means of a synapse, to a connecting neuron called the relay neuron situated in the spinal cord.
