Introduction:

The olfactory receptors are located in the nose of vertebrates. Olfactory bulbs are part of brain where olfactory nerves form synapses with interneurons and send signals to cerebral cortex of brain in the form of action potential. The chemical present in environment act as cues that trigger the generation of action potential in the olfactory receptors. It has been observed that the olfactory bulb is larger in case of diurnal birds.
