Meissner's corpuscles are usually contrasted with Pacinian corpuscles for touch sensitivity (and possibly others, which might also be mentioned). In addition, Meissner's are sensitive to stroking sensations as well as fluttering, as is mentioned here:

The article pacinian corpuscles says "They function as mechanoreceptors, detecting gross pressure changes and vibrations.". I haven't looked for any other reference for the "gross pressure" part, so I'll leave it until I find one. — Ashley Y 00:58, 2005 Jan 18 (UTC)
In my opinion a comparison between the Meissner's corpuscles and Pacinian corpuscles is a good addition to the article. I do not understand why Wikipedia's two pro-circumcision activists, Robert and Jake, want to delete the information about Pacinian corpuscles. -- DanBlackham 05:33, 18 Jan 2005 (UTC)
I don't see what the big deal is about leaving in the comparison to Pacinian corpuscles. They are both common mechanoreceptors. Should a new article called "Comparison of mechanoreceptors" be created to make it "on-topic"? By the way, to whoever removed the "gross pressure", Pacinian corpuscles are found in the pancreas. It would obviously take more than slight pressure to activate the nerve in the corpuscle... -- jag123 14:43, 18 Jan 2005 (UTC)
I really couldn't care less about circumcision. For those of you who want the comparison removed, have you ever looked at any histology or biology textbooks? Are you aware how many times those two encapsulated nerve endings are mentionned together, side by side or one after another? I strongly oppose any kind of mention of circumcision in this article. If mentionning two common and often "paired" pressure corpuscles is off-topic (which I think it isn't), then mentionning anything about circumcision is beyond ludicrous. Not every article on Wikipedia needs to be a huge debate. Has it really become this pathetic? It seems one can't even adequetaly describe a simple structure without having to worry about POV. You want to be pro/anti-circumcision? Good for you but take it elsewhere. -- jag123 03:53, 20 Jan 2005 (UTC)
I think you're missing the point, Robert. They're both pressure receptors. One is at the boundary of the epidermis and detects light touch, stroking and whatnot, while the other is more deeply embedded and detects deep pressure. The fact that the two mechanoreceptors complement one another is the reason why they're often mentioned together in biology texts, and a good reason to mention the Pacinian corpuscle in an article about Meissner's corpuscle. -- Tony Sidaway| Talk 05:55, 20 Jan 2005 (UTC)
Didn't read it all, just wanted to say both are rapidly adapting mechanoreceptors and are the end-organs of class A α,β fibres (almost identical in that sense). Both are carried to the cerebral cortex over the dorsal-column medial lemniscal system, without giving off lateral branches at their corresponding spinal segments. All these are common for both and especially the property of not giving off lateral branches upon entering through the dorsal roots is unique. This property is utilized by clinical neurologists to examine lesions in the dorsal column, an additional twist of the flutter-vibration (the name flutter has been proposed by Mountcastle in this article: Talbot et al but it never really made it into other articles). You could MERGE THE TWO TOPICS and not a single neurologist would notice (a neuroscientist would murder though), that's how identical the two are (and how blunt the clinical neurologists are).--Meral Rc. 05:38, 31 May 2011 (UTC)
I've inserted some external references that give the excellent anatomical reasons for linking these two nerve cells together, and written a paragraph highlighting the reason why academic texts up to undergraduate level often introduce them together. Robert is quite right; the Pacinian corpuscle article should also link to Meissner's corpuscle. I suggest that a "See also" link would be sufficient there as the link is quite adequately dealt with here; alternatively we could add the Meissner's and Pacinian corpuscle to a new article about this class of nerve cell. It should be possible to find a way of linking the two that correctly reflects the extremely close anatomical similarities and satisfies everybody. -- Tony Sidaway| Talk 15:38, 22 Jan 2005 (UTC)
If Robert's intent was to remove what he perceived as anti-circumcision bias from this article on anatomy, he knew he'd lost the minute I showed up and started editing. All we're doing here is deciding the terms on which the anatomical link between two different types of encapsulated pressure sensor is discussed in this and related articles. My feeling at present, subject of course to further discussion, is that I will go with any recommendations you have to make, and I feel that together we have the persuasive power to make them stick. -- Tony Sidaway| Talk 22:35, 22 Jan 2005 (UTC)
I went ahead and did a rewrite. I removed the stroking and fluttering mention because I think it's redundant (they deal with touch, regardless if it's stroking, fluttering, etc). I've also explained a bit more how the phasic part works in the receptor. I (purposely) didn't mention Ruffini endings or Merkel's disc because they are slowly adapting and my example (a poke) would not necessarily activate either. In addition, I think that because it's clearly mentionned that they stop firing after a while, no one should assume that Meissner's corpuscle are responsible for feelings of constant pressure, so explaining Ruffini or Merkel's might seem superfluous. On the other hand, I felt it important to point out that pain is not generated from MCs. By the way, what's the deal with corpusculum tactus? Is there a reason why it's in latin? -- jag123 04:00, 25 Jan 2005 (UTC)
Looks good to me. -- Tony Sidaway| Talk 08:09, 25 Jan 2005 (UTC)
This a touch receptor. It detects touch, whether it's stroking, caressing, tapping, rubbing, petting, etc regardless if it's light, soft, strong or whatever. It also detects vibrations, which includes fluttering (depending how you define it). Is there any special reasons why these need to be added? -- jag123 02:37, 31 Jan 2005 (UTC)
For the record, I have asked Ashley Y on her talk page to explain why it is important to mention stroking. Her reply was that she was happy with Jakew's edit. Since no reasons have been presented, I will be removing those edits. -- jag123 03:56, 1 Feb 2005 (UTC)
How about this wording? "It detects touch, including stroking, tapping and rubbing." Petting and caressing are redundant. --

Why is this so important? What's the difference between stroking and rubbing? Seriously though, is this going to boil down to whether or not Oxford/Webster's considers them synonyms or not, or even worse, everyone's interpretation of those definitions? If that's what it's going to be about, I'll go with whatever word Jakew or Robert recommend, so long as it essentially means the same thing or is a synonym. Maybe that will even things out. </sarcasm> -- jag123 10:23, 1 Feb 2005 (UTC)
Please don't be sarcastic, I'm trying to be helpful. You inserted a graphic example of the kind of stimulus that Pacinian corpuscles react to (a poke) at the same time that you removed all graphic examples of the kind of stimulus that Meissner's corpuscle reacts to. The words I'm suggesting are the words that you yourself gave on this talk page. I'm fine with any reasonable synonyms as long as the reader has a clear picture of the kind of motion that causes Meissner's corpuscles to fire in my lips when I move my finger across them. You ask "why is this so important?" Well I'm beginning to wonder the same thing. Why do you keep removing helpful graphic descriptions of the kind of stimulus the Meissner's corpuscle responds to? -- Tony Sidaway| Talk 10:32, 1 Feb 2005 (UTC)
I apologize for the sarcasm. The purpose of the poke example is to clearly explain that although MC do get activated, the greater "jist" of the sensation is from PCs. If it weren't for PCs, you couldn't tell the difference between something that is resting on your skin, or jabbing into it. (I ignore FNEs to keep things simple.) On a slightly different note, this is the reason I object to the specifying of "light" touch. Unless there's a study out there that shows that MCs do nothing at all if the touch passes a certain threshold, then it's just not true. In my opinion, it's crystal clear that when I read touch, it's any and all kinds of touch. I don't see why someone would assume that a particular mode/way/method/whatever of contact does not count. In light of my recent experience with Ashley Y, it became obvious to me that her adding "stroking" serves only (at the very least) to piss off (maybe overly sensitive ?) activists. I do not believe that she is adding stroking for informational purposes. This, along with my previous reasons, is why I want to keep it out. However, if you can find someone else besides the five of us (only because we all know each other's position regarding adding/leaving it out) who sees value in adding stroking (or ideally another appropriate synonym), then I will go with whatever they say. At the same time, perhaps that/those person(s) could comment on whether or not mentionning Pacinian is of any value to them. Apart from you, I don't really know anyone well enough to ask them for their opinion, but I think you might be in a better position. If you can't/don't want to find anyone, then for the sake of putting this to bed, I'll agree to anything but the word "stroking" because for whatever reason (sexual connotation? used often with "penis" in a sentence?), it's causing unnecessary disruptions. -- jag123 11:41, 1 Feb 2005 (UTC)
Thanks. Your explanation of the modality (that it'll still react to a jab) makes sense to me. I didn't appreciate that before. -- Tony Sidaway| Talk 11:48, 1 Feb 2005 (UTC)
I agree FNE detect pressure but Pacinian corpuscles are more suited for deep pressure, simply because of their location in the dermis. Any objections to moving "deep pressure" beside Pacinian? -- jag123 02:50, 31 Jan 2005 (UTC)
I've temporarily removed the claim that Meissner's corpuscles are found in nipples, since it is contradicted by the following. I haven't read the other sources; if they claim otherwise then we ought to note the differing sources.
"AREOLA AND NIPPLE Martynoff18 found Golgi-Mazzoni, Vater-Pacini and genital corpuscles in the areola and nipple. Belonoschkin19 observed what he termed a "Krause end-bulb in the areola and nipple. Cathcart and colleagues20 did not confirm these findings. They found no Meissner corpuscles and few organized endings of any nature." -- Winkelmann, 1959 (emph added).
