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.

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.

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.

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.

Fertilization. Colored scanning electron micrograph (SEM) of a sperm (blue) attempting to penetrate a human egg (orange).
