Definition of Aponeurosis

I'm no expert but shouldn't the definition above include the fact that an aponeuroses can exists as a broad, flat tendon that may serve as either the origin or insertion of a flat muscle? The current definition seems to indicate aponeuroses only separates muscles from each other. —Preceding unsigned comment added by Bluepattern (talk • contribs) 19:06, 12 October 2007 (UTC)

The covering of a muscle is usually called the epimysium. Aponeurosis is more related to tendon, as its name suggests. Scientifically, the aponeurosis seems to be considered as a continuation of the tendons. Often over the surface of the muscle, but in some instances, such as the anterior aponeurosis of the soleus muscle, it lies roughly in the middle of the muscle (www.ncbi.nlm.nih.gov/pubmed/16453292). These arrangements are because many muscles are composed of a 'pinnate' arrangement of muscle fibers. (pinnate - pinna - feather-like) Muscle fibers are arranged at an angle to the long axis of the muscle and attach directly to aponeuroses. Thus aponeuroses are considered to be force-transmitting structures rather than simply a tissue covering the muscle. Not sure if it should be included here, but the pinnate arrangements confers interesting mechanical properties on the muscle, some of which are poorly understood. One is that the tendon/aponeurosis move a greater distance along the muscle axis than the muscle fibers shorten, thus amplifying the muscle fiber length change (www.pnas.org/cgi/content/full/105/5/1745). Willing to attempt edits if these comments seem appropriate. This is my first attempt here, so help/encouragement would be appreciated. QuietJohn (talk) 20:46, 8 May 2008 (UTC) QuietJohn

Palmar Aponeurosis

Is this relevant? "...are referred to in the Patrick O'Brian Aubrey–Maturin series of books." I don't think this section should be here if that is going to be the only content. Mbarden 16:01, 24 May 2007 (UTC)

I agree. SteveD 23 September 2008 —Preceding unsigned comment added by 220.245.248.148 (talk) 22:04, 22 September 2008 (UTC)

palmar

I would suggest that 'palmar region' be replaced with 'palm', or 'the palm of the hand'. The goal here is to explain, not to obscure. I clicked on the palmar link, and it took me five minutes of digging to find out that palmar was just the palm of the hand. — Preceding unsigned comment added by 74.38.234.96 (talk) 17:16, 5 August 2011 (UTC)

You mean like the place in the page where it explicitly states "The palmar aponeuroses occur on the palms of the hands."? Mokele (talk) 02:37, 6 August 2011 (UTC)

Word etymology

It appears to be an implication, based on Wiktionary and numerous other sources, that aponeurosis is named as such because "neuro" means "sinew" means "tendon". Contrarily, I haven't found a single other term in English where 'neuro' isn't used to refer to nerves. Further contrarily, an anecdotal source in fact claims the word "neuro" in aponeurosis refers to nerves; specifically, that the original meaning of the word was the aponeurosis of the skull, which anatomically is located "away from" "nerves" (in relation to the skull), and that other aponeuroses were named after this first one (source: an anatomy textbook author).

I (shallowly) suggest taking an official stance not to add an entire new, confusing, contradictory, poorly sourced meaning of the word 'neuro' to the English language through this term, through post-applying a suggestive, non-committal, non-historical etymology that actually makes sense, employing speculative sourcing. I have yet to find other sources to confirm the history of the word (else this would be no issue). Having it listed on Wikipedia would be very helpful. Gewath (talk) 12:14, 31 January 2021 (UTC)
