I have tried to tidy up this page, removing inconsistencies and repetitions. Still needs more. I suggest that the Receptive field section at the end should be moved to the somatosensory section of the
Receptive Field article.

The article claims 'merkel cells also have two point discrimination.' Surely all mechanoreceptors have this, just with differing limen magnitudes? — Preceding

Are Merkel cells encapsulated?
The opening sentence of the Electrophysiology section says that Merkel cells are not encapsulated. I have seen conflicting information online about whether Merkel cells are encapsulated or not:
As of this writing (March 11, 2024), the
OpenStax open Biology textbook, 2e even disagrees with itself, with the text saying they are, "Merkel’s ... are slow-adapting, encapsulated nerve endings", but the Figure 36.5 caption saying they are not, "Merkel’s disks, which are unencapsulated". (I made an OpenStax
errata submission pointing out the discrepancy.)
I do not have the expertise to decide if the current Wikipedia content is incorrect. I just wanted to point out the possibility.
New editor, feedback welcome, but note that I am a layperson without access to the primary sources, which is why I used NIH and ScienceDirect links. Thank you.
