Micro Monsters: scanning electron microscope images of insects, spiders and creepy crawlies  Coloured scanning electron micrograph (SEM) of a maggot head    "I've tested the book out on my son Ned and it hasn't given him any bad dreams, in fact he loves it. In particular Ned likes like the nasty worms."    A maggot head

Leaf surface. Coloured scanning electron micrograph (SEM) of the varied underside of a leaf from a rice plant (Oryza sp.). Leaves have a wide variety of specialised surface structures, such as trichomes (not seen), stomata (pores) and oil glands. Magnification: x830 when printed 10 centimetres wide.

Nerve cells. Coloured scanning electron micrograph (SEM) of nerve cells, known as neurones. Nerve cells occur in the brain, spinal cord, and in ganglia. Each nerve cell has a large cell body (brown) with several long processes extending from it. The processes usually consist of one thicker axon and several thinner branched dendrites. The dendrites collect information in the form of nerve impulses from other nerve cells and pass it to the cell body.

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.

Blood clot. Coloured scanning electron micrograph (SEM) of a blood clot from the inner wall of the left ventricle of a human heart. Red blood cells (erythrocytes) are trapped within a fibrin protein mesh (cream). The fibrin mesh is formed in response to chemicals secreted by platelets (pink), fragments of white blood cells. Clots are formed in response to cardiovascular disease or injuries to blood vessels. Connective tissue (orange) is also seen.

Cochlea from Inner Ear. Color-enhanced SEM of the inside of a guinea pig inner ear showing the hearing organ, or cochlea. Running along the spiral structure are rows of sensory cells which respond to different frequencies of sound. The whole organ is just a few millimeters long.
