What kind of sensory receptor detects changes in temperature?
What kind of sensory receptor detects changes in light/light intensity?
What is the Pacinian Corpuscle?

Using the Pacinian Corpuscle as an example, how does a nerve impulse start?
Why do we react to some stimuli but not to others?
What really is a nerve?
What are Myelin Sheaths?
What is the difference between dendrites and dendrons?
