I was recently asked the following question:
Compare the following pairs of receptors in the same sensory system. Include in your discussion:
- The distribution in the sensory epithelium;
- What kind of stimulus is effective in activating them;
- Their physiological response properties, function and central connections.
- Rods and cones
- Pacinian corpuscles and free nerve endings
In particular, I was not sure what the sensory epithelium is. Is it getting at the fact that Pacinian corpsucles are subcutaneous, while free nerve endings are cutaneous and that cones are centralized at the fovea?
Alos, I am not sure what their "physiological response properties" refers to. Since they are receptors, would their responses just be the output (i.e. peripheral/foveal vision and vibration/pain sense)?
