Stomach lining, SEM C016 / 9068
Stomach lining. Coloured scanning electron micrograph (SEM) of the lining of the stomach, known as the mucosa. The stomach is a muscular sac involved in storage and digestion of food

Smell receptor, TEM
Smell receptor. Transmission electron micrograph (TEM) of a section through the olfactory epithelium that lines the nasal cavity, showing an olfactory cell (smell receptor)

Trachea lining, SEM C015 / 9610
Trachea lining. Coloured scanning electron micrograph (SEM) of the lining of the trachea (wind pipe). The trachea links the larynx to the lungs

Tongue, light micrograph C015 / 7105
Tongue. Light micrograph of a section through healthy tongue tissue. The surface of the tongue (across top) consists of stratified squamous epithelium (dark purple) with a rough keratinised surface

Trachea lining, SEM C015 / 9609

Anatomy in the 18th C
a skull, teeth, the interior of a knee (below left) some marrow and a mucous gland from the humerus (below right) Date: Circa 1760

Snail foot. Foot of a garden snail (Helix aspersa) crawling over glass, seen from below. Snails have a single foot. Movement is created by successive contractions of the muscles inside the foot

Small intestine villus, SEM
Small intestine villus. Coloured scanning electron micrograph (SEM) of a freeze fracture section through a villus from the mucosal lining of the small intestine

Nose mucosa, light micrograph
Nose mucosa. Light micrograph of a section through the nasal mucosa (the tissue that lines the airways of the nose), in the region lying over the nasal concha

Salivary gland, light micrograph
Salivary gland. Coloured light micrograph of a section through a sublingual salivary gland, which is situated directly under the tongue

Runny nose. Artwork of a section through the ear, nose and throat of a patient with excessive mucus production due to a cold or hay fever (allergic rhinitis)

Nasal polyp, light micrograph
Nasal polyp. Light micrograph of a section through a nasal polyp, a benign growth that arises from a mucous membrane. Magnification: x150 when printed at 10 centimetres wide

Trachea mucous membrane, SEM
Trachea mucous membrane. Coloured scanning electron micrograph (SEM) of a fractured mucous membrane of the trachea (wind pipe), showing the epithelium and underlying connective tissue

Frog skin glands, light micrograph
Frog skin glands. Light micrograph of a section through the skin of a frog, showing secretory glands (round, upper centre) just below the surface (across top)

Nasal mucosa, artwork
Nasal mucosa, cross-section. Artwork of a sequence (left to right) showing mucus production in response to infection and inflammation

Asthma and mucus overproduction, artwork
Asthma and mucus overproduction. Artwork showing how the bodys immune response causes the inflammation seen in asthma. The chest of a human figure is at top right

Small intestine lining, light micrograph
Small intestine lining. Light micrograph of a section through the finger-like projections (villi) of the duodenum, the uppermost part of the small intestine

Snake ciliated lung cells and mucus, SEM
Snake ciliated lung cells and mucus. Coloured scanning electron micrograph (SEM) of ciliated cells (green) and mucus (pink) in the lung of a snake
