Life Cycle of a frog 3 of 5 (Tadpole development) (UEB Uncontracted)
This is a multi-page image of the four stages of tadpole development, set on two pages. There are locator dots shown, which will be at the top left of each page when the images are the right way up. Each illustration has a scale showing its approximate size. Page 1: This page shows two illustrations of a tadpole with its head to the right of the page and its tail to the left. It is shown from the side so only one eye can be found. At the top of the page the tadpole is at an early stage of development. It still has gills to get its oxygen from the water, one of which can be found just to the left of its eye. At the bottom of the page the tadpole has grown and lost its gills. It has now developed so that it can breathe air through its mouth. Page 2: This page shows two more stages of development of the frog tadpole with its head to the right and tail to the left. At the top of the page the tadpole is viewed from the side with only one eye visible. One of its recently formed back legs can be found along the bottom edge of its body and the little bud of one of the emerging front legs can be found to the left of its mouth. At the bottom of the page the tadpole is seen from above. At the right of the image both of the tadpoles eyes are on view. To the left of this its front legs can be found and further left its back legs and tail. It is beginning to change from its 'fishy' shape to one that is more froglike.
Life Cycle of a frog 5 of 5 (Adult frog) (UEB Contracted)
This page is filled with the image of an adult frog stretched out to its full length. It is seen from above with its head at the top and back legs at the bottom. There is a locator dot shown, which will be at the top left of the page when the image is the right way up. To the left is a scale showing the approximate size of its body. In the top centre of the page is the frog's upper lip with two eyes slightly down from this. The frog's front legs, extending out to hand-like feet, can be found to either side. The frog's rounded body is in the centre of the page with two lines in the middle indicating the boney structure of its back. The lower half of the image shows the frog's two well-muscled rear legs extending down from its body and ending in three-toed feet at the bottom of the page.

Section through a molar tooth (Large Print)
This is an image of a molar tooth. There is a locator dot shown, which will be at the top left when the image is thenbsp;correct way up. The image is surrounded by an image border. The top of the tooth is at the top of the page and the root and jawbone at the bottom of the page. The components are labelled. The enamel, the grinding surface, is the upper layer. Down from this is the dentine layer which is slightly softer and surrounds the inner core which is the soft pulp containing the nerve and blood vessels. Going down to the bottom of the page are the two roots of the tooth which hold it firmly in place in the jawbone. The nerves and blood vessels come from the ends of the roots and go off to the left.

This is an image of an incisor tooth. There is a locator dot shown, which will be at the top left when the image is the right way up. The image is surrounded by an image border.The top of the tooth is at the top of the page and the root and jawbone at the bottom of the page. The components are labelled. The enamel, the cutting surface, is the upper layer. Down from this is the dentine layer which is slightly softer. The inner core is the soft pulp which contains the nerves and blood vessels. Going down to the bottom of the page is the root of the tooth which holds it firmly in place in the jawbone. The nerves and blood vessels come from the end of the root and join the main vessels in the jaw shown in cross section as a dot.
