Receptors that provide animals with information from the external environment are located in the:
- ears
- skin
- tongue
- eyes
- nose
These receptors are known as sensory receptors as they perceive the changes that occur in the external environment and transmit the information to the nervous system.
The name of these receptors located in the respective organ is as follows :
1. Ear - auditory receptor
2. Skin - mechano (cutaneous) receptors
3. tongue - taste receptors
4. eyes - Photoreceptors
5. nose - olfactory receptors
An example of how it detects the changes in the external environment can be understood as follows :
The substances that have odor produce chemicals known as odorants which bind to the olfactory receptors located in the nose which then produces electric signals which are transmitted via the nerves to the olfactory bulb in the brain and the smell is detected.

This was a law proposed by V. E. Shelford in 1911.
