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.

Colored scanning electron micrograph (SEM) of squamous cell carcinoma (cancer) cells from a human mouth. The many blebs (lumps) and microvilli (small projections) on the cells' surfaces are typical of cancer cells.

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.

Ruptured capillary. Coloured scanning electron micrograph (SEM) of a red blood cell squeezing out of a torn capillary. A capillary is the smallest type of blood vessel, often only just large enough for red blood cells to pass through. Red blood cells (erythrocytes) are biconcave, disc-shaped cells that transport oxygen from the lungs to body cells. Credit: STEVE GSCHMEISSNER/SCIENCE PHOTO LIBRARY

Bone marrow, coloured scanning electron micrograph (SEM). This freeze-fracture has revealed the cavity (lumen) of a large venous sinus (pink), which contains mature blood cells (red), and developing white blood cells (blue). Either side of the sinus are the haemopoetic foci of the marrow (green). Magnification: x3000 when printed at 10 centimetres across | Steve Gschmeissner

Using a Scanning Electron Microscope, retired scientific photographer Steve Gschmeissner, 61, from Bedford, is able to magnify insects by up to a million times. The results show incredibly detailed images of creepy crawlies in 3D  A coloured scanning electron micrograph of the head of a human flea (Pulex irritans)

Peyer's patches (green), coloured scanning electron micrograph (SEM). These regions of lymphoid tissue are found in the human intestine, usually in the ileum, the final section of the small intestine.

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

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.

Brain tumour. Coloured scanning electron micrograph (SEM) of a glioma, a type of tumour that arises from glial cells of the central nervous system. The most common site for gliomas is the brain. They can be either low or high-grade, with the latter having the worse prognosis. Magnification: x8000 when printed at 10 centimetres wide.    Credit: STEVE GSCHMEISSNER
