What are different types of information that your body can detect from the outside world? 2. What organs does your body use to collect the information described in the last question?
Senses Gizmo, you will explore how different sense organs detect stimuli from the environment and send messages about that stimulus to the brain. On the NEURAL PATHWAYS tab, drag the apple slice into the white Stimulusbox. Drag the eye into the Sense organbox. Click Play(1. What do you observe? 2. How do you know that the eye senses the apple? ). 3. The neural pathwayrepresents the nervesthat connect the sense organ to the brain. What happens along the neural pathway when the eye sees the apple?
Light receptors at the back of the eye are activated by incoming light
