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.
A reflex is a quick involuntary action. There are five steps to a reflex: the stimulus occurs, the sensory neurons sense the stimulus, it sends a message to your spinal cord (â¦ it doesn't reach the brain right then), the spinal cord sends a message to your motor neurons, and the reflex occurs.he signal goes up the sensory nerve to the spinal cord and then down a motor nerve to produce the motion. All of the processing of the signal is done in the spinal cord. An autonomic reflex involves different centers in the brain and does not always trigger motion.
