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.
1-7. REFLEX ARC An impulse follows a conduction pathway from its origin in the dendrites or neuron cell body in one part of the body to the impulse's end somewhere else in the body.One pathway is called a reflex arc and is a functional unit of the nervous system.The basic parts of a reflex arc are a receptor, a sensory neuron, a center, a motor neuron, and an effector. a. Function of Components of a Reflex Arc.Functions are: (1) Receptor. The receptor activates a nerve impulse in a sensory neuron in response to a change in the body's internal or external environment.(2) Sensory neuron. This neuron conducts the impulse from the receptor to its axonal end in the central nervous system.he receptor activates a nerve impulse in a sensory neuron in response to a change in the body's internal or external environment. (2) Sensory neuron. This neuron conducts the impulse from the receptor to its axonal end in the central nervous system.
