Lenz Law is a way to find the direction of induced current in a conducting loop. As per Faraday's Law of electromagnetic induction, a current is induced in a conducting loop by the changing magnetic flux. This induced current itself produces a magnetic field and hence a magnetic flux.
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.
As discussed earlier, a reflex involves at least 2 or 3 neurons. The typical components of a reflex are shown in Figure 13.12. The reflex shown in this figure is called a 3-neuron reflex because it requires three types of neurons: a sensory, an interneuron, and a motor neuron.heir function, like that of stretch reflexes, is the coordination of muscles and body movements. The deep tendon reflex involves sensory neurons, interneurons, and motor neurons. The response reverses the original stimulus therefore causing relaxation of the muscle stimulated.
