Description
Radiograph of the head and neck of a giraffe (Giraffa camelopardalis). This radiograph is part of Professor Ian Taylor's work on angiosomes - three dimensional anatomical units of tissue fed by a source artery. In the early 1990s, a giraffe at Melbourne Zoo had to be euthanized because of a spinal injury and was offered to the Anatomy Department. To produce this radiograph, the body of the giraffe was injected via the carotid artery with a radiographic mixture consisting of lead oxide, gelatine and water. The mixture was allowed to set overnight, the skin was removed superficial to the deep fascia, spread like a carpet, and x-rayed separately from the deep musculoskeletal tissues. The dark brown patches on the giraffe’s skin were encircled with copper wire and the skin was radiographed again. On this radiograph, the dark skin patch margins are marked in orange texta, the nerve supply in green. The numerous small, black rectangles are clips on the vessels at the level they enter the subcutaneous tissue layer.
