Sense Organs (WJEC GCSE Science (Double Award)): Revision Note

Sense Organs

• Sense organs are groups of receptor cells which respond to specific stimuli such as light, sound, touch, temperature and chemicals (e.g. smell and taste)

  • Receptor cells are groups of specialised cells

  • They detect a change in the environment and stimulate electrical impulses in response

• Sense organs relay the information from receptor cells as electrical impulses along neurones to the central nervous system
