Kirlian image of a fingertip

Kirlian photograph of the "corona discharge" from a person's fingertip. Kirlian photography is also known as electrophotography, & high voltage or radiation field photography. It obtains a photographic image due to interactions between the subject & an applied electric field. No external light source is used; light emitted as photons from the electrical interaction produces the image on film. A controversial medical application of the technique involves correlating the physical & mental well-being of a subject with image variation arising from differences in sweat rate & sweat composition on the skin surface


Adult hand X-ray Featured 17 Feb 2004 Print

Adult hand X-ray

Adult hand bones. Coloured X-ray of the healthy hand of an adult, showing the bone arrangement. An outline of the flesh is seen. Bones of the hand consist of eight small carpals in the wrist (centre left), which articulate with the two long forearm bones (far left). Five metacarpal bones (at centre) make up the palm of the hand. Each finger has three phalanges, except the thumb which has two such bones. This skeleton enables the human hand to be used with great flexibility, helped especially by the joint between the wrist and the opposable thumb. This well-adapted hand allowed our ancestors to use tools, facilitating human evolution
