Pain and Pleasure…

There are bodily cells for pain (Nocireceptors), but there are no such bodily cells for pleasure.
Sure we have endorphins and other neurotransmitters, but how is it that we feel pleasure?
Is it that we generally feel pleasure in receiving information from other types of receptors (i.e. the receptors for Touch, Pressure, Vibration, Warmth, Cold, Proprioception, Smell, Taste, Vision, Hearing and Equilibrium).
Could it be that a sense of aesthesia is related to them, or is it just a Neurotransmitter, like an Endorphin, activating pleasure in the site of such bodily cells?

(To note, is that, we also have neurotransmitters for pain.)

I don't really know much about hedonics but I suppose it depends on how you look at pleasure and pain.
I mean I suppose if you think in terms of evolution and the fight or flight response, pain and fear are necessary to recognise dangerous situatiions and deal with them so I can understand why pain receptors as it were would need to be hard wired in. Pleasure on the other hand is more something to do with motivational drives.

Why does this make you angry??? lol

ya I would agree with Sorceress, pain is associated to the body making the mind aware of problems, like the fire is hot or that fall broke my ankle and the corresponding reaction of move your hand from the fire or don't try to walk on that ankle. So the brain needs to know the location of these problems for it to respond to the stimulous.
