the article seems to be not general enough. E.g. as far as I know in zebrafish the myotome wont loose its metamerical arrangement (see e.g. Kimmel et al, Stages of embryonic development, 1995), but in mammals it will, as the article says.)

I am considering developing this page further as part of an educational assignment in Fall of 2013. If someone else is also working on this, please send me a message and let me know soon, so we don’t duplicate initial efforts in page development. Quigend (talk) 22:29, 6 October 2013 (UTC)[reply]

Go for it! I'll stay out of the way (or give what help I can). HCA (talk) 00:34, 7 October 2013 (UTC)[reply]

This page could use some serious organizing and tightening up of the definition of myotome. Additionally, I think it would be beneficial for the page to clearly lay out how the myotome arises from the dermomyotome and information about the formation of myotomal fibers. It would also be interesting to include information on the role and regulation of myosin expression during myotome formation. Sections should be made for myotome formation in mammals (for which there is information on mice and humans) and non-mammals (for which there is information on zebrafish).

Myotome Map?

I'm trying to remember some muscle innervations, and am reminded that it was difficult (I'm not sure I ever succeeded) to find a visual representation of the myotome muscle innervations. Is there some technical reason that this is not feasible? Google isn't helping me, I just keep getting dermatome maps (I think that Google's search engine has dermatome and myotome as synonyms). Dermatomes do not correspond to muscle innervations. For example, the biceps brachii is innervated by c5 and c6, but the dermatome that sits on top of the bicep is t1, which is a pretty huge difference. If a myotome map is feasible, I think that it would be a great addition to this page. I don't have the skills for it, but if anyone else does... SCooley138 (talk) 19:53, 20 October 2013 (UTC)[reply]

I've taken a moment to think about it, and I realized that this would be very challenging. There are a lot of deep muscles, and that would be difficult to represent visually in a way that can easily be understood. I think it's probably possible, but pretty difficult. Still, there are some pretty ambitious and talented contributers on wikipedia. SCooley138 (talk) 20:10, 20 October 2013 (UTC)[reply]

Move reverted

This is a long-established and substantial article, "Myotome". A recent stub, barely more than a dictionary definition, was created at Myotome (anatomy), and an editor decided there was no "primary topic" for the term "Myotome", and moved this to Myotome (embryology). They did not fix any of the incoming links. I have reverted that move, and added a hatnote to refer readers to the new stub. If someone believes that there is no primary topic for "Myotome", they should do a formal WP:RM to move this page to a disambiguated title, and then create a disambiguation page at the base name and, most importantly, fix all the incoming links to the existing page so that they still point to that page and not the disambiguation page.

Another editor, a member of the Anatomy Wikiproject, then decided that the new stub was on the existing topic and merged and redirected. I'm leaving it to the anatomy/embryology experts to decide what to do now - but please make sure that all necessary links / redirects / hatnotes / dab page are made so that readers can all find what they are looking for.

Thanks PamD. I was going to post here but then I forgot about it, sorry! I saw the move/revert and noticed the duplication, and have merged and restructured the articles. I have rerated the pages and fixed the hatnote, please let me know if there's anything else I can do. --LT910001 (talk) 09:25, 20 April 2014 (UTC)[reply]

Mix of content

This article refers to two separate topics - one relating to anatomy and the other to embryology. Iztwoz (talk) 08:23, 20 April 2014 (UTC)[reply]

Agree the article is quite confusing at present. I'll add it to the 'to improve' list and get to it shortly =P. --LT910001 (talk) 09:26, 20 April 2014 (UTC)[reply]

Now that it's being done (sorry, I wasn't paying attention, my bad), I'm wondering if it's right to split them? I mean, yes, one refers to the embryonic tissue while the other refers to existing muscle groups, but at the same time, the grouping of muscles into myotomes is due to the embryological segmentation. It's a little non-inuitive in humans because so much is either modified or in limbs, but in something like a salamander or fish, each embyrological myotome forms a segment of adult axial musculature linked to a vertebra and a spinal nerve in a very straightforward way. Honestly, IMHO, the best image for this page would be a fish fillet - each of the bands of muscle are myotomes, separated by collagenous myosepta, originating from the embryonic myotomes.
