Receptor :

It is a cell or group of cells specialised to detect a particular stimulus and to initiate the transmission of impulses via the sensory nerves.

The receptors pass information to the brain through a type of nerve cells called sensory neurones.

• Phono receptor (Ears) : For sound
• Gustatory receptor (Tongue) : For taste
• Olfactory receptor (Nose) : For smell
• Thigmo receptor (Skin) : For touch
