Explain the type of reflexes.

Explanation

There are two types of reflexes. They are
1. Unconditional reflex is an inborn reflex for an unconditioned stimulus. It does not need any past experience, knowledge or training to occur, Ex: blinking of an eye when a dust particle is about to fall into it, sneezing and coughing due to foreign particle entering the nose or larynx.
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. Example: 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.
