Which are the sensory organs for smell and taste? Give brief information.

(N/A) The sensory organs detect all types of changes in the environment and send appropriate signals to the $CNS$,where all the inputs are processed and analysed. Signals are then sent to different parts/centres of the brain. This is how you can sense changes in the environment.
We can smell through the nose and detect taste through the tongue.
- The nose contains mucous-covered sensory receptors that receive stimuli of smell; these are called olfactory receptors.
They are made up of olfactory epithelium,which consists of three types of cells:
$(a)$ Bipolar olfactory nerve cells
$(b)$ Columnar epithelial cells
$(c)$ Mucous glands
Olfactory receptors are linked with the olfactory bulb,which is an extension of the limbic system.
- The olfactory bulb is situated at the anterior lobe of the cerebral hemisphere,beneath the ethmoid bone.
- The nose and tongue both recognize soluble chemicals. In gustation (taste) and smell,chemical sensations are functionally similar and interrelated.
- The tongue identifies tastes via taste buds,which possess taste receptors.
Each food or drink's taste is connected with various inputs in the brain,which gives the sensation of complex tastes.
