•  Receptors detect changes in the environment

Sensitivity describes the ability of an organism to detect external and internal changes and respond accordingly

  • Receptors detect these changes as stimuli, and generate nerve impulses which are relayed to the brain and effector organs
  • There are different types of receptors that each recognise a different type of stimulus (temperature, light, etc.)
