Nerve bundle. Coloured scanning electron micrograph (SEM) of a freeze-fractured section through a bundle of myelinated nerve fibres. Myelin sheaths (yellow) can be seen surrounding the axons (blue). Perineurium (connective tissue, pink) surrounds the nerve bundle while endoneurium divides the individual fibres.
Mold ,Aspergillus versicolor,. Conidia ,asexual spores, are produced on the conidiophores ,fruiting structures / sporangia,. Aspergillus versicolor is very common in damp places. This genus can also cause skin infections in burn victims and the fungal lung infection aspergillosis ,secondary infection to AIDS
Coloured scanning electron micrograph (SEM) of an Arachnoidiscus japonicus diatom. Diatoms are single-celled photosynthetic algae, of which there are about 100,000 species. They have mineralised cell walls (frustules) that contain silica and provide protection and support. The diatoms form an important part of the plankton at the base of the marine and freshwater food chains.
Seen here is the cells of the largest organ in the human body: the skin. This scanning electron micrograph shows the epidermis, which is the tough, outermost coating of the skin, formed by overlapping layers of dead skin cells that are continuously removed and replaced by the living cells underneath.

Iris pigment epithelium. Coloured scanning electron micrograph (SEM) of a section through the iris of an eye, showing the iris pigment epithelium (IPE). The IPE is a layer of cuboidal cells (pink) that lies behind the iris. Each cell contains numerous large melanosomes (blue), which contain the pigment melanin. The concentration of this melanin is one of the factors that determine the colour of a person's eye. Magnification: x3,300 when printed 10 centimetres wide.
