LM of four-cell embryo
Four-cell embryo. Light micrograph of the blasto- meres of a four-cell human embryo, two days after fertilisation. The blastomeres are the rounded cells

Hair root, SEM
Hair root. Coloured scanning electron micrograph (SEM) of the root (red) and part of the shaft (yellow) of a human hair. The base of the hair is known as the hair bulb and is the site of hair growth

Coloured SEM of a fertilized human egg (zygote)

Sperm fertilising egg

LM of blastomeres of a two-cell embryo
Two-cell embryo. Light micrograph of the blasto- meres of a 2-cell human embryo, two days after fertilisation. The blastomeres are the rounded cells formed by the first division of the fertilized

Human sperm

Mitotic cell division, TEM
Mitotic cell division. Coloured transmission electron micrograph (TEM) of a cell during the metaphase stage of mitosis (cell division)

Periodontal ligament fibres, SEM
Periodontal ligament fibres. Coloured scanning electron micrograph (SEM) of periodontal ligament fibres (red). These fibres, a specialised type of connective tissue

Ovarian tissue, SEM
Ovarian tissue. Coloured scanning electron micrograph (SEM) of a section through the medulla of an ovary showing blood vessels (pink)

Kidney tubule, TEM
Kidney tubule. Coloured transmission electron micrograph (TEM) of a section through a proximal convoluted tubule in the kidney

Duodenal microvilli
Microvilli in duodenum. Coloured transmission electron micrograph (TEM) of a section through the human duodenum, showing microvilli on the surface epithelium (lining)

Coloured TEM of microvilli of intestinal cell

Liver capillary, SEM
Liver capillary. Coloured scanning electron micro- graph (SEM) of a freeze-fractured section through liver tissue showing a hepatic capillary, or sinusoid

Corpus luteum, SEM
Corpus luteum. Coloured scanning electron micrograph (SEM) of a corpus luteum, or yellow body (brown), in an ovary. The corpus luteum is formed after ovulation

Coloured SEM of glomeruli in the human kidney

Pancreas cell, TEM
Pancreas cell. Coloured transmission electron micrograph (TEM) of an acinar (exocrine) pancreatic cell. Acinar cells secrete the inactive precursors (zymogens)

Kidney glomerulus
Glomerulus. Coloured scanning electron micrograph (SEM) of a healthy kidney glomerulus. The glomerulus is a tight ball of capillaries where blood passing through the kidneys is filtered

Coloured SEM of a sectioned villus from the ileum

Kidney podocyte cells, SEM
Kidney podocyte cells. Coloured scanning electron micrograph (SEM) of podocyte cells on the surface of a kidney glomerulus. Podocytes possess branching, foot-like processes (red/brown)

Trachea lining, TEM
Trachea lining. Coloured transmission electron micrograph (TEM) of a transverse section through the lining of the trachea (windpipe). The trachea links the larynx to the lungs

False colour SEM of entrance to gastric gland
False-colour scanning electron micrograph (SEM) of the mucous membrane lining the stomach, showing the entrance to a gastric gland

Stomach wall, SEM
Stomach wall. Coloured scanning electron micrograph (SEM) of a section through a freeze- fractured fold in the stomach wall

Ear canal, SEM
Ear canal. Coloured scanning electron micrograph (SEM) of hairs growing in an ear canal. The ear canal runs between the outer ear and the eardrum

Kidney tubules, SEM
Kidney tubules. Coloured scanning electron micrograph (SEM) of proximal convoluted tubules (dark brown) in the kidney. The proximal convoluted tubules function to reabsorb water

Immunofluorescent LM of normal breast cells

Inner ear balance sensing, SEM
Inner ear balance sensing. Coloured scanning electron micrograph (SEM) of bundles of cilia (hair cells, yellow) and otoliths (round, red) in the human inner ear

False-colour SEM of gastric glands of stomach
Gastric gland: false-colour scanning electron micrograph (SEM) of the mucous membrane lining the stomach, showing the shadowy entrances to a number of gastric glands

Rod cells. Coloured scanning electron micrograph (SEM) of rod cells (green) in the retina of the eye. Rod cells are light-sensitive cells which respond to dim light

Purkinje nerve cells

Coloured SEM of femoral spongy bone

Bone, SEM
Spongy bone. Coloured scanning electron micrograph (SEM) of freeze-fractured spongy bone tissue. It shows the matrix of collagen and calcium crystals that form the structure of bone tissue

Smooth muscle, SEM
Smooth muscle. Coloured scanning electron micrograph of smooth muscle from the trachea (windpipe). Smooth muscle is not under voluntary control, unlike skeletal (striated) muscle

Spongy bone, SEM
Spongy bone. Coloured scanning electron micrograph (SEM) of human spongy (cancellous) bone from the shaft of a long bone. Found inside bones, below a dense shell of hard compact bone

Coloured SEM of section through human spleen
Human spleen. Coloured Scanning Electron Micro- graph (SEM) of a section through the human spleen. Here, the fine network of reticular fibres known as trabeculae is seen
