In any case, here's a usage/grammar guide: </p> <dl><dd>"Mucus" is a non-countable noun.</dd> <dd>"Mucous" is an adjective (apparently meaning something close to "mucus-secreting").</dd> <dd>"Mucosa" is a singular noun (apparently referring to a mucus-secreting membrane); "mucosae" is its plural.</dd></dl> <p> I haven't made the effort (even to the extent of reading further in the article) to learn all the reasons why the word is countable, and if i were using it, i would be wary about whether e.g. one person has a single nasal membrane or e.g. two nasal mucosae --one in each nostril-- or (in a not necessarily ridiculous flight of fancy) an odd number of nasal mucosae (perhaps e.g. a left <a href="/wiki/Distal" class="mw-redirect" title="Distal">distal</a> and a right distal mucosa (one inside each nostril), plus a single <a href="/wiki/Medial_(anatomy)" class="mw-redirect" title="Medial (anatomy)">medial (anatomy)</a> mucosa that wraps (behind and above the nostrils) around that beloved chunk of cartilage (<a href="/wiki/Nasal_septum" title="Nasal septum">nasal septum</a>?) that separates the two nostrils. (Surely two unrelated people have distinct mucosae, but if a mucosa gets cut in half, is it then just one (split) mucosa or --perhaps only until surgically repaired-- two separate nasal mucosae?) I'm not sure dicts clarify that, but even if they do, that kind of problem is specialized enuf that it may be more effectively covered in WP than in Wikt or any other dict.<br/> I think i <i>will</i> add a bit of (arguably lexicographic and thus dubiously encyclopedic) text, stating that mucosae is the plural -- since i am not alone in never having studied Latin -- thus immunizing others against the confusion i experienced. I trust my colleagues to deliberate whether my enthusiasm has again run away with me.<br/>--<a href="/wiki/User:Jerzy" title="User:Jerzy">Jerzy</a>•<a href="/wiki/User_talk:Jerzy" title="User talk:Jerzy">t</a> <a href="https://en.wikipedia.org/wiki/Talk:Mucous_membrane#c-Jerzy-2017-04-29T05:35:00.000Z-Grammatical_number" class="ext-discussiontools-init-timestamplink">05:35, 29 April 2017 (UTC)</a><span class="ext-discussiontools-init-replylink-buttons" data-mw-thread-id="c-Jerzy-2017-04-29T05:35:00.000Z-Grammatical_number"><span class="ext-discussiontools-init-replylink-bracket">[</span><a class="ext-discussiontools-init-replylink-reply" role="button" tabindex="0" href="">reply</a><span class="ext-discussiontools-init-replylink-bracket">]</span></span><span data-mw-comment-end="c-Jerzy-2017-04-29T05:35:00.000Z-Grammatical_number"></span><br/> </p>    </div><noscript><img src="https://login.wikimedia.org/wiki/Special:CentralAutoLogin/start?type=1x1" alt="" width="1" height="1" style="border: none; position: absolute;"></noscript> <div class="printfooter" data-nosnippet="">Retrieved from "<a dir="ltr" href="https://en.wikipedia.org/w/index.php?title=Talk:Mucous_membrane&oldid=1195642511">https://en.wikipedia.org/w/index.php?title=Talk:Mucous_membrane&oldid=1195642511</a>"</div></div> <div id="catlinks" class="catlinks" data-mw="interface"><div id="mw-normal-catlinks" class="mw-normal-catlinks"><a href="/wiki/Help:Category" title="Help:Category">Categories</a>: <ul><li><a href="/wiki/Category:Start-Class_Anatomy_articles" title="Category:Start-Class Anatomy articles">Start-Class Anatomy articles</a></li><li><a href="/wiki/Category:Top-importance_Anatomy_articles" title="Category:Top-importance Anatomy articles">Top-importance Anatomy articles</a></li><li><a href="/wiki/Category:Anatomy_articles_about_microanatomy" title="Category:Anatomy articles about microanatomy">Anatomy articles about microanatomy</a></li><li><a href="/wiki/Category:WikiProject_Anatomy_articles" title="Category:WikiProject Anatomy articles">WikiProject Anatomy articles</a></li><li><a href="/wiki/Category:Start-Class_Molecular_Biology_articles" title="Category:Start-Class Molecular Biology articles">Start-Class Molecular Biology articles</a></li><li><a href="/wiki/Category:Unknown-importance_Molecular_Biology_articles" title="Category:Unknown-importance Molecular Biology articles">Unknown-importance Molecular Biology articles</a></li><li><a href="/wiki/Category:Start-Class_MCB_articles" title="Category:Start-Class MCB articles">Start-Class MCB articles</a></li><li><a href="/wiki/Category:Mid-importance_MCB_articles" title="Category:Mid-importance MCB articles">Mid-importance MCB articles</a></li><li><a href="/wiki/Category:WikiProject_Molecular_and_Cellular_Biology_articles" title="Category:WikiProject Molecular and Cellular Biology articles">WikiProject Molecular and Cellular Biology articles</a></li><li><a href="/wiki/Category:All_WikiProject_Molecular_Biology_pages" title="Category:All WikiProject Molecular Biology pages">All WikiProject Molecular Biology pages</a></li></ul></div><div id="mw-hidden-catlinks" class="mw-hidden-catlinks mw-hidden-cats-hidden">Hidden category: <ul><li><a href="/wiki/Category:Pages_with_broken_anchors" title="Category:Pages with broken anchors">Pages with broken anchors</a></li></ul></div></div> </div> </main> </div> <div class="mw-footer-container"> <footer id="footer" class="mw-footer" > <ul id="footer-info"> <li id="footer-info-lastmod"> This page was last edited on 14 January 2024, at 18:25<span class="anonymous-show"> (UTC)</span>.</li> <li id="footer-info-copyright">Text is available under the <a href="/wiki/Wikipedia:Text_of_the_Creative_Commons_Attribution-ShareAlike_4.0_International_License" title="Wikipedia:Text of the Creative Commons Attribution-ShareAlike 4.0 International License">Creative Commons Attribution-ShareAlike 4.0 License</a>; additional terms may apply.
