Smell receptor

Coloured transmission electron micrograph (TEM) of a section through the olfactory (smell) epithelium of the nose. At centre (orange) is an olfactory receptor cell body. At its top two long, modified non-motile cilia project into the liquid lining of the nasal cavity. The cilia are thought to be the sites of interaction between odiferous substances and the receptor cells. Surrounding the receptor cell are the supporting cells with surface microvilli (finger-like). Within the cells, mitochondria (purple) & endoplasmic reticulum (flattened sacs) are seen.

  1. Some good pareidolia here ... I can see a considerable number of faces and bodies of fictitious beasts.

    1. The big "face" looking toward the right was one of the reasons I posted the image. :>)

  2. That's a pretty nice bit expressionism. That'd look pretty good, framed and hung.

  3. That'd make a gorgeous quilt...

    1. It is a microscopic photograph of the cells in the nose that detect smells.
