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.
Human Anatomy & Physiology Reflex Physiology lab Objectives: To understand what reflexes are, the processes involved, and purpose of reflexes. Introduction: A reflex is an involuntary neural response to a specific sensory stimulus that threatens the survival or homeostatic state of an organism.n humans and other vertebrates, protective reflexes have been maintained and expanded in number. Examples are the gag reflex that occurs when objects touch the sides or the back of the throat, and the carotid sinus reflex that restores blood pressure to normal when baroreceptors detect an increase in blood pressure.
