I noticed that if I take something pointy (like a pen, for example) and poke a random spot on the inside (the palm side) of my hand, I can tell if it’s hitting the center. The center of the palm seems to have different feeling. In fact, I have the ability to tell how far the center is from the spot that I’m poking. So I can easily move the pen to the spot that is the center. Does anyone know what I’m talking about?
Are you high, man? 
No. But good idea!
Well, the skin in the center of your palm is more taut that the skin around it and has less fat and muscle tissue underneath it; plus nerves tell you the location of pressure inputs in pretty much the whole skin surface of your body with danr good accuracy… so no, I´ve got no idea of what you´re up too with this. 
I’m sorry for posting this weird thread and then deserting it for the weekend. But this is just something I noticed a while back. The exact point of the center of my palm just feels differently than the rest. I don’t know how else to explain it. It occurs on both palms, plus the soles of my feet, the center of my inner wrists and other areas.
If I take something sharp, like the tip of a pen, and then poke a random spot on my palm, I can tell when it’s the exact center. There’s a tiny, tiny point that represents the exact center (possibly of nerve endings?). If no one knows what the hell I’m talking about, please disregard. Maybe I’m just special*.
*I understand that “special” can have variuos connotations.
That’s the section reserved for hair growing, should you decide to…
I have the same exact thing you are describing. I’ve known it since I was a child. I have never found anyone else with this. I can pinpoint the exact location of the center of my palms and under my feet. Since I am a Christian I always thought it had to do with Christ’s wounds.
How do you know what the “center” of your palm is? It is not symmetrical like a circle – have you measured it and used whatever complex mathematics is needed to determine the true center?
And what do you mean by saying that if you poke your palm off-center you can tell “how far” off-center you poked? Do you mean you somehow just knew that your pen poked 1.3 inches away, and discovered that when you measured it that the feeling of 1.3 inches was borne out by the measurement?
This is a zombie, but since the OP is still around, I’ll leave it open.
Unlikely, since crucified people are nailed through the wrists, not through the hands.
ETA: or, were, I should say. I hope nobody’s out there crucifying people nowadays.
How is this any different from knowing where you are being touched on any other part of your body’s surface?
Your skin is covered by touch receptors. The ones on places like your fingertips are smaller and more densely packed (high sensitivity). The ones on the backs of your hands are have larger and sparser receptors areas. The palm is somewhere in the middle (but closer to your fingertips).
One common test for testing sensitivity: grab two pens, or a compass (the drawing kind), or calipers or something. Put both points close together on your skin, and without looking, slowing separate the points until you can feel two things poking you. This distance will likely be much larger on less sensitive areas, e.g. it takes you longer to notice it’s two points and not one. You could try this on center vs. more distal palm parts. I don’t know why the center would be more sensitive but it’s worth I try. I kind of feel it; it’s much more ticklish towards the center. It’s also more of a “pit” in the middle of the palm.
Here is a web site with an artist’s rendition of a human body distorted by the number of touch sensors. Isn’t he a charmer?
I can’t find anything specific on this, but I do know that the center of the palm is an erogenous zone, along with the inside of the wrist, back of the knees and a few other places. This may be less to do with the number of nerves as with the lower likelihood of these areas being touched accidentally. Thus, it would be a function of acclimatization rather than nerve ending density.
BTW, googling “palm nerve ending map” comes up with a strange mix of pages…
Most entertaining thing I have read this week. KUDOS.
Yes yes yes YES! I know exactly what you’re talking about.
jacknifed juggernaut, I think you’re still around. Read this very similar thread I started in which a couple of people get it but everyone else tells me I’m weird.
I had a lump in one palm that was not in the other.
Since it was different, I decided it was not something important like bone or muscle and started to worry about it. But decided I didn’t want an x-ray, at least not yet, so I started scraping and poking it with a needle. Thought it might be a blister of some sort.
Turned out it was a heavy callous around a rose thorn I had thought I’d removed but missed the tip.
Sorry I’m late back to this party. Glad I’m not alone. 
I know exactly what Jackknifed Juggernaut and jjimm are talking about (thus proving it has nothing to do with having multiple 'J’s [or 'j’s, as the case may be] in one’s user name.)
I’ve never really thought much about it because I just figured that *everybody *felt the same way…
