//////////////Someday we will understand the mechanisms involved, and it will still
seem amazing, just as irridescense still seems beautiful even though
we understand the optical phenomenum that produces it.
When people refer to the 5 senses, they are generally talking about
messages that bodily organs capable of recognizing external stimuli
send via the peripheral nervous system to central nervous system
consciousness. The retina has 2 types of neruons, rods and cones,
the one better at registering light intensity and the other color,
but the retina is a single organ; the tongue has 4 types which can
variously register sweet, sour, bitter, and salty; the skin has a
bunch which include those that register light pressure, deep
pressure, heat, cold, pain and so forth, which we lump together as
touch or tactile sense. In terms of the middle ear, so far as I know
there is only one type of neuron, and it registers both intensity and
frequency of vibrations, but I could be mistaken about that.
The inner ear registers internal body stimuli - the movement caused
by gravity of fluid across the cilia therein, as do the various
stretch receptors throughout the body, which all add up to
equilibrium and position sense. Hunger and thirst are also the
results of internal body stimuli, but I'm unclear as to where the
relevant neurons are located. I suspect that as in the case of
position sense, the involved neurons are widespread. Other
receptors, such as baroreceptors that monitor blood pressure in the
carotid artery, are responding to internal stimuli of which we are
not generally aware.
Our conscious sense reception of odors is so atrophied that for the
most part we pay little attention to it except insofar as it
contributes to our experience of taste. I don't know if there are
different types of neurons that specialize in recognizing different
types of chemicals that are blown our way, or just differing
receptors on those neurons. It is my understanding though that the
neurons that detect pheromones in the vollmar body are different, and
their axons travel to the brain separately from those in the nasal
mucosa, (which like skin, is a diffuse organ that serves several
functions). Perhaps one might rightly lump pheromone detection
together with the sense of smell. What intrigues me is that
uniquely, the vollmar body registers external stimuli, but does not
communicate what it has found to our consciousness. And it was not
discovered until near the end of the last century.
The word sense has several meanings, and when talking about a sense
of humor or beauty or awe, we are talking about one of its other
meanings. These are more to be considered as emotional responses to
interpretations of the environment made by the conscious brain, not
as messages sent to the brain via the peripheral nervous system by
organs that pick up stimuli from the environment.
