Okay, we can attach photos to posts via thumbnails but the upload quota is very small, so what is the main purpose of the thumbnail upload facility (being so small) and how do I delete what I have already uploaded so I can use it again?

I like being able to upload something I have on my computer quickly rather than having to upload it to photobucket first, but since I have used all of my 100K quota, is there a way to delete the old uploads and put in new ones??

Enquiring minds want to know.....

I was sorely disappointed when I found out this was about those digilectronic thumbnails. I've always wondered why my fingers have little helmets.

Lunula (anatomy)


From Wikipedia, the free encyclopedia

Jump to: navigation, search
Lunula Basic nail anatomy The lunula is the white crescent-shaped area of this finger. Latin lunula Code TH H3.12.00.3.02006
The lunula, or lunulae (pl.) (little moon in Latin), is the crescent-shaped whitish area of the bed of a fingernail or toenail. The lunula is the visible part of the nail matrix (i.e. the root of the nail).
In humans, it appears by week 14 of gestation, and has a primary structural role in defining the free edge of the distal nail plate (the part of the nail that grows outward).
[edit] Appearance

It is located at the end of the nail (that is closest to the skin of the finger), but it still lies under the nail. It is not actually white but only appears so when it is seen through the nail. Outlining the nail matrix, the lunula is a very delicate part of the nail structure. If one damages the lunula, the nail will permanently be deformed. Even when the totality of the nail is removed, the lunula remains in place and is similar in appearance to another smaller fingernail embedded in the nail bed.

It is half-moon-shaped, and has unique histologic features. Examinations concluded that the lunula was an area of loose dermis with lesser developed collagen bundles. ^[1]

The lunula is most noticeable on the thumb, however, not everyone's lunula is visible. In some cases, the eponychium may partially or completely cover the lunula.
