Talk:Sagittal plane

Midsagittal should be merged into the page as a minor point - it's a sagittal plane that cuts through the nose. There's not enough info for the two to be separate. WLU 20:28, 19 July 2007 (UTC)

Differences

The following paragraph should not be in this page, as it refers to the midsagittal plane only. Which should be merged.

Differences between the two halves, assymmetries, are found primarily in the heart and other internal organs, but subtle differences can also be seen in the two halves of the human face. Try holding a pocket mirror with its edge against the center of your own photo, showing one side reflected to make a whole face.

It's also proscriptive with the mirror bit. WLU 20:31, 19 July 2007 (UTC)

An image of an arrow piercing a body and passing from front (anterior) to back (posterior) on a parabolic trajectory would demonstrate the derivation of the term.

It would actually take two arrows to define it in this way, although one could define the coronal plane as being normal to the one arrow, if it struck just right. --70.131.60.45 (talk) 00:11, 6 November 2008 (UTC)

Restricted context

The term sagittal is a geomeric term rather than a medical term. Thus a more general Wikipedia article is needed. —Preceding unsigned comment added by 150.227.15.253 (talk) 12:31, 26 July 2010 (UTC)

Abduction and adduction are defined WRT the sagittal plane - not the coronal plane, as written here. —Preceding unsigned comment added by 129.55.200.20 (talk) 18:49, 4 March 2011 (UTC)

is it head or body?

If I turn my head, then the definition is not fully clear to me. Is it from the front to the back of my head or my body? Just from the initial definition I'd say ”body”, but then the “Terminology” section mentions the “sagittal suture”, which would hint for “head”. -- 77.117.3.192 (talk) 09:36, 5 March 2012 (UTC)

"Relative" is unclear

The article says that Extension and flexion are the movements of limbs relative to the sagittal plane and Abduction and adduction are terms for movements of limbs relative to the coronal plane but what does "relative" mean? Along, parallel and perpendicular to are all relationships that a movement can have with a plane. Which relative is it? — Preceding unsigned comment added by 92.25.1.159 (talk) 00:11, 12 September 2013 (UTC)

That does seem awkward and the opposite of what I would think is logical. If a movement is flexion or extension, the body part moves away from (perpendicular to) the coronal plane while in abduction or adduction, movement is away from (perpendicular to) the sagittal plane. As currently written, Citation needed! Thank you, Wordreader (talk) 03:05, 26 September 2014 (UTC)

Perhaps the author meant to say that flexion/extension is along (parallel to) the sagittal plane and abduction/adduction is along (parallel to) the coronal plane? Thanks, Wordreader (talk) 03:11, 26 September 2014 (UTC)

Changed "relative to" to "within". From Classic Human Anatomy by Valerie L. Winslow, page 32: "The movements that occur within the sagittal plane are angular movements, primarily flexion and extension. Flexion (bending) usually takes place in the anterior direction, forward from the anatomical position. The exception is the flexion of the knee, in which the lower leg moves only in the posterior direction, backwards from the anatomical position." FLeℵgyel (ta|k) 19:29, 27 October 2015 (UTC)

See also - Distal plane? As I understand it, proximal (closer to the head) and distal (farther from the head) are relative directions or contexts, not cutting planes. Examples: "The feet are distal to the hands." -or- "The neck is proximal to the waist." Thank you, Wordreader (talk) 03:18, 26 September 2014 (UTC)

incomprehensible illustration

It took a long time before i discovered the much too thin brace and realized the reason why there's no black plane in the illustration... --Espoo (talk) 16:47, 4 June 2023 (UTC)
