Lung cancer cell division.  Coloured scanning electron micrograph (SEM) of a lung cancer cell during cell division (cytokinesis). The two daughter cells remain temporarily joined by a cytoplasmic bridge (centre). Cancer cells divide rapidly in a chaotic, uncontrolled manner. They may clump to form tumours, which invade and destroy surrounding tissues.

Shark Skin: Scales from the skin of a shark. These sharply pointed placoid scales are also known as dermal teeth or denticles. They give the sharks skin the feel of sandpaper. The tip of each scale is made of dentine overlayed with dental enamel. The lower part of each scale is made of bone. The scales disrupt turbulence over the skin, considerably reducing the drag on the shark as it swims. This design has recently been investigated by engineers for use on the surfaces of aircraft and…

Axones nerviosos - A cross section of a bundle of nerve fibers.  Axons (orange) are wrapped in myelin (purple); an extension of the membrane of glial cells.  Myelin has high lipid content, and acts to insulate the axons, causing them to transmit nerve impulses much faster.
