Explain the type of reflexes.

Explanation

There are two types of reflexes. They are-
(i) Unconditional reflex is an inborn reflex for an unconditioned stimulus. It does not need any past experience, knowledge or training to occur, eg: Blinking of an eye when a dust particle about.to fall into it, sneezing and coughing due to foreign particle entering the nose or larynx.
(ii)Conditioned reflex is a respone to a stimulus that has been acquired by learning. This does not naturally exists in animals. Only an experience makes it a part of the behaviour. eg: Excitement of salivary gland on seeing and smelling a food. The conditioned reflex was first demonstrated by the Russian physiologist Pavlov in his classical conditioning experiment in a dog. The cerebral cortex controls the conditioned reflex.
