Why does a medical doctor often tests the knee for reflexes? What is it really testing for ? Surely not that single area for a single purpose (reflex). What am I missing?
In: Biology
When you hit the knee, it triggers nerves that do not travel up to your brain (that’s why your knee kicks without you thinking to do it).
This gives a measure of the conductivity of your nerves without involving your brain.
The reflex arch goes knee sensory neuron > spine > knee motor neuron.
