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.
Superficial Reflexes. 1  Corneal reflex (blink reflex). 2  Involuntary blinking in response to corneal stimulation. 3  Afferent: nasociliary branch of ophthalmic branch (V1) of trigeminal nerve (5th nerve). 4  Efferent: facial nerve (7th nerve). 5  Abdominal reflex. 6  Contraction of superficial abdominal muscles when stroking abdomen lightly.
