Talk:Sulcus (morphology)

Sulcal variability

I have removed the following, since I don't think it is correct:

The patterns of sulci and gyri are the same in all individuals (baring malformation) and can thus be named and provide a consistent method of mapping and referring to various areas of the brain.

is a sulcus the same as a fissure

my understanding is that a sulcus is not a fissure. In humans there is the longitudinal fissure that separates both hemispheres and this is not a sulcus. The same goes for a sylvian fissure. zorkerz (talk) 18:15, 7 December 2008 (UTC)

Merger with Sulci (anatomy)

Agree. These are two articles for the same thing and the articles are close to if not identical. I have no preference on with name to use. JakobSteenberg (talk) 11:54, 24 April 2013 (UTC)

Merge from Fissure (anatomy)

The following discussion is closed. Please do not modify it. Subsequent comments should be made in a new section. A summary of the conclusions reached follows.

There is consensus not to merge Fissure (anatomy) into Sulcus (morphology). There is consensus that the topics are distinct, and that the reader would be served better with a separate development of each concept on its own page. Felix QW (talk) 21:00, 24 June 2022 (UTC)

I propose merging Fissure (anatomy) into Sulcus (morphology). These are different terms for the same thing. Further, I don't think the current Fissure article should be the primary topic of of Fissure (disambiguation), as most non-biologists would think of an Earth fissure when they hear the word "fissure". If these articles are in fact merged as I propose, then I suggest adding an entry for Sulcus (morphology) to the Fissure (disambiguation) page. In any case, the current contents of the Fissure article, which is about anatomy, should be merged into Sulcus (morphology). 18:43, 14 September 2021 (UTC) — Preceding unsigned comment added by Coastside (talk • contribs) Revised since Fissure is no longer primary topic Coastside (talk) 05:36, 21 September 2021 (UTC)

• Oppose and improve both. the terms are not actually analogues when used in botanical literature and often not when used in entomological literature. Currently both articles are very vertebrate/human-cetric and do not fully cover the topics enough to demonstrate they are not synonyms.--Kevmin § 21:19, 14 September 2021 (UTC)

@Kevmin: Regarding these not being synonyms, the lead sentence in the Fissure (anatomy) article says "It is also generally called a sulcus...". Would you say that's incorrect?16:51, 20 September 2021 (UTC) Revised Coastside (talk) 05:37, 21 September 2021 (UTC)

• Oppose. I think Kevmin makes a very good point about there being separate elements within these, and even in human anatomy I think it is easier to have the articles separate. If they had to be merged, I would propose to something like Fissues and sulci although that is not my preferred option. Tom (LT) (talk) 00:39, 16 September 2021 (UTC)
• Oppose in the narrow sense, per Kevmin - but I would definitely agree the biological focus is not necessarily the dominant one. A fissure is, as the DAB has it, "a deep, elongated groove or tear"; the material is variable, no? At the very least, an explicit link on to the various geological uses would be important. I am also going to revise the lede on the DAB to reduce (but not remove) the dominance of the anatomical definition; hope that's uncontroversial. DanHobley (talk) 15:42, 20 September 2021 (UTC)

Please also comment at Talk:Fissure (disambiguation)#Primary topic as to whether you think the anatomical use of fissure should be the primary topic. It's a separate discussion from whether Fissure and Sulcus (morphology) should be merged, although obviously these topics are related.Coastside (talk) 16:56, 20 September 2021 (UTC) Revised Coastside (talk) 05:36, 21 September 2021 (UTC)

Seems not much more input. I still don't see how Fissure (anatomy) and Sulcus (morphology) are different. The lead of the Sulcus (morphology) article defines sulcus as ... a furrow or fissure. It uses the word fissure to define sulcus, and it's clear this is 'fissure' in the sense of anatomy (not geology for example). And the Fissure (anatomy) article lead says "in anatomy... [a fissure] is also generally called a sulcus". How are these topics different? Coastside (talk) 17:37, 21 September 2021 (UTC) Also, I looked up morphology (biology), and it distinguishes between external and internal morphology. Internal morphology is defined as anatomy.Coastside (talk) 17:41, 21 September 2021 (UTC)

In botany Sulcus is used in terms of indents or areas between two features, such as the in the Acer pseudoplatanus and Acer campestre samaras in the images. The sulcus is the space between the samara wing base and the nutlet tip, with the depth and angle of the sulcus are specific defining features, especially in the fossil taxa.--Kevmin § 18:20, 21 September 2021 (UTC)

Oppose and would suggest a better move would be to change page name from Sulcus (morphology) to Sulcus (anatomy) as term is used a lot, separately from Sulcus (neuroanatomy). The disambiguation page could be used to cover other uses. In the botany uses sulcus as a groove would be enough?--Iztwoz (talk) 09:41, 1 November 2021 (UTC)
