Lateral/Sagittal plane?
At the bottom of this article, one image's description claims that the mediastinum is not visible in a lateral view. However, it would be visible in a mid-sagittal plane. Is there a diagram we could use to illustrate this? Myoglobin (talk) 13:53, 6 April 2018 (UTC)

delineated or undelineated
The first sentence of this article is currently,
 * "The mediastinum is the central compartment of the thoracic cavity surrounded by loose connective tissue, as an undelineated region that contains a group of structures within the thorax."

In the online Cambridge dictionary, "delineate" is defined to mean, "to describe or mark the edge of something"; in the Oxford Learners Dictionaries, as, "to describe, draw or explain something in detail"; Merriam-Webster, as, "to describe, portray, or set forth with accuracy or in detail" or, "to indicate or represent by drawn or painted lines", or, "to mark the outline of"; Collins, "If you delineate something such as an idea or situation, you describe it or define it, often in a lot of detail."

I do not understand therefore in what sense the word "undelineated" is being used here. The whole article is a setting forth with accuracy and detail of what the mediastinum is and the first sentence of the next section, Structure,
 * "The mediastinum lies within the thorax and is enclosed on the right and left by pleurae. It is surrounded by the chest wall in front, the lungs to the sides and the spine at the back. It extends from the sternum in front to the vertebral column behind, and contains all the organs of the thorax except the lungs."

provides a precise delineation in the other sense of defining the precise boundaries of the region.

Does undelineated have some special meaning in medical context or ought this word to be dropped from the lead? Hedles (talk) 07:54, 26 April 2020 (UTC)
