xiphoid cartilage and xiphisternum #50

Closed cmungall closed 9 years ago

cmungall commented 13 years ago

many resources treat these as synonymous, but MA has two terms:

MA:0001334 ! xiphisternum [part_of: "sternum"] MA:0001884 ! xiphoid cartilage [SYNONYM: "xiphoid process" (related)] [subclass: "cartilage"]

should these be merged? If not, what is the difference. Is it cartiliginous vs ossified? If so I suggest adding an is_a parent to bone for 1334 and a part_of to sternum of 1884

for comparison:

FMA:7488 ! Xiphoid process

(an organ process: neutral w.r.t bone or cartilage)

FMA:32574 ! cartilage of xiphoid process

FMA:32577 ! bone tissue of xiphoid process

Sorry for the delayed response. This issue just came up with regards to another project. I believe that the terms should be merged.

MA:0001334 and MA:0001884 have been merged and renamed: "xiphoid process". Synonyms include: "xiphisternum" and "xiphoid cartilage". Upon examination of the scientific literature for the mouse, these appear to be the most widely used terms and appear to be used synonymously. Other synonyms have been cited by various resources, however it is unclear whether they have been used for the mouse.

Examination of the literature has so far produced no indication for ossification of the mouse xiphoid process. However, I certainly cannot exclude the possibility. So, the question is whether "xiphoid cartilage" should be a synonym of "xyphoid process", or is used to indicate specifically either (1) only those cases in which the xyphoid process is not ossified, or (2) only those parts of the xyphoid process that are not ossified. The FMA differentiates between cartilage and bone with regards to the xiphoid process, but it appears that xiphoid-related cartilage is not considered to be part of the xiphoid process itself. It remains unclear whether this distinction is appropriate for the mouse.
