Stimulus and Response
by Anonymous · ⭐ 1 · 🍴 0
In Signal Path, you have to set the order to sensory neuron → association neuron → motor neuron yourself before a signal can travel all the way to a response — get the order wrong and it stops partway. You'll also see that a reflex skips the brain, bouncing straight back from the spinal cord, which is why it's faster. In Nerve vs. Hormone, compare how a nerve signal is fast but reaches only one place, while a hormone is slow but spreads through the blood to many places at once — growth hormone, insulin, glucagon, and thyroxine all work this way. In Blood Sugar, raise and lower blood sugar by eating, exercising, and letting time pass, then switch off insulin or glucagon and watch blood sugar get stuck away from its normal level of 100. Keeping the body steady turns out to be teamwork between nerves and hormones.
About this app
Stimulus and Response is an interactive middle-school biology app about how the nervous and hormonal systems coordinate body responses. In the Signal Path tab, arrange sensory, association, and motor neurons in the correct order, compare a brain pathway with a faster spinal reflex, and observe where an incorrectly ordered signal stops. The Nerve vs. Hormone and Blood Sugar tabs demonstrate fast, targeted nerve signaling, slower blood-borne hormone signaling, and insulin- and glucagon-based blood sugar regulation.
Use cases
- Middle-school students studying neurons and reflexes
- Teachers demonstrating stimulus-to-response pathways
- Learners comparing nervous and endocrine signaling
- Students exploring insulin and glucagon in blood sugar control
Features
- Interactive neuron-order activity using sensory, association, and motor neurons
- Comparison of brain pathways and direct spinal reflex pathways
- Nerve-versus-hormone comparison for speed and distribution
- Examples featuring growth hormone, insulin, glucagon, and thyroxine
- Blood sugar controls for eating, exercise, and letting time pass
- Toggle insulin and glucagon to observe blood sugar returning—or failing to return—to normal
