hi it's good to see you again I'm John Cowan and I the director of the Mini Medical School will start this week with anatomy and physiology and continue those areas next week to let's start now by talking about an ad methods Anatomy is the fundamental basic science medicine so people have been studying it for a long time here's a picture for anatomical Atlas said to be based on actual dissection of the body's it was made in China in the Song Dynasty well over a thousand years ago here's the front page and a muscle dissection from a 16th century Atlas for medical studies by the Brussels or an anatomist Vesalius it's one of the most books ever made  this famous painting by the Dutch Master Rembrandt shows us that Anatomy was not just for doctors but of great interest to fashionable in the 17th century it's possible that the tableside dissection guide they have handy on the right with visalia's but we need modern technique modern times in the early 1990s a male cadaver was preserved and then cut into about 1,700 slices in the anatomy department at Medical School in Colorado each slice was photographed at high resolution and the data were digitized and archived at the US National Library of Medicine which funded project from that data set a computer can recreate the body for examination in ways never before possible we'll take a trip through the body from top to bottom imagine that he's lying on his back with his feet towards you will move from top to bottom and what is called transfers or horizontal action the right hand side of the image that you see is the body's left side will stop occasionally to point out features the brain with white and gray matter the eyes and object nerves air in the nasal cavity and sinuses which shows up is blue note the trachea or windpipe the esophagus and one of the vertebrae of the backbone the lungs the heart strong muscles this is the left ventricle the ribs the backbone vertebral column protecting the spinal cord which connects the brain and the body  as we go down notice the flashing of vertebral bones and the bright discs between them which add flexibility and padding  through the diaphragm the liver the stomach we're still at the level of the upper arm because there is only one bone here  now the kidneys and small intestine the blue is air in the large intestine or bowel the muscles of the thigh in front the quadriceps and behind the hamstrings the broad surface of the knee joints cartilage and the protective knee cap now we'll take a quick trip going through the play from front to back remember it wasn't cut this way but was reconstructed in the computer this way from the original data set  and now a trip from side to side similarly computed medical students have access computerized tableside dissection guide based on the visible human while they learn their anatomy in the First Medical School course fortunately you learn a lot of anatomy from books and websites and as you learn more in this course you can always come back to this video and work your way through the body again
