Seeing the picture of the baby with two heads, is your first reaction a charade or fear? Most people are staring at the grotesque look of two heads while completely ignoring the deadly truth about the connection between the back bones. This rare conjunctural malformation is not a simple "replicating paste" and the way in which the spinal column is integrated with the thorax directly determines the boundaries of the operation. You think it's just an extra head? It's a mistake to actually let a surgeon sweat on the operating table, the anatomical knot hidden under a shared vein. If this critical structure is not understood, any attempt at separation is tantamount to a direct death sentence. Do you dare to look at the bloody medical game behind this picture?

You may not have noticed that the number of bones in babies is completely different from that of adults.——At birth, there were more than 270, nearly 70 more than the 206 for adults. The bones that look like "excessive" are not burdensome, but are connected to the cartilage that is hidden in the skull and the gill, and they will be cremated and boned in the years to come, and will eventually be shaped into adult skeletons that you know. But in this silent bone remodelling project, there is a risk window that is ignored by the vast majority of parents: Some of the seemingly normal "soft bones" are early signs of abnormal growth. Which are the areas where the skeletal delay requires vigilance and which are normal individual differences?

Do you think it's just a static setup? When the arms and legs can be removed and reorganised at will, the classic white skeleton becomes, in an instant, a "felter" that breaks the body's structural consciousness. Most people see a smaller proportion, but they ignore the joint logic that's hidden in Section B's design.——It gives you a good sense of muscle attachment without touching a real body. But what really doubles the efficiency of anatomy learning is not the size, but the order of disassembly that was ignored by 90 per cent of the population. Are you sure you really understand every joint of it?

You search the human bone model online, and the results come out in the same way as "precision" and "medical standards", but it turns out that either the joints are loose like toys, or they're far too far apart from teaching. 45 CM may seem to be the right size, but those who really know how to do it know that a small size model is the best test for the business, because any detail is magnified when the scale is scaled up. It's not a talk. It's just a selection of the core of the small skeletal model.——And why, in practice, certain electricians are not at all suitable for professional use.

In the face of this 85CM neurovascular skeletal model in front of you, do you think it's just an anatomy? The finely written design of that side is actually the easiest "cognitive trap" for medical entrants. Most people stare at the bone structure with hard backs and ignore the colored vascular neuropaths.——And this is exactly the invisible map of life and death in clinical surgery. When you can tell the logic behind this half-colour, you don't have to worry about the boring black and white picture, but if you don't understand the design, the expensive model is just a pile of resin. What kind of anatomical secret is implied by the color of this half?

You stare at the normal bone model on the wall, do you always find it hard to remember the dry muscles as if they were books? This 85CM-mounted model solves the pain in a very violent way.——It just splits the body: half shows muscle stop points, half bare bones and ligaments. Such a strong visual comparison is an instantaneous blow to the space logic that the plane map cannot convey. When you're still working on the hard copy book, those who know how to do it are already using this wallchart to get to know the toughest stereoidization. Is it a medical student's walker or is it just a scary decoration? After this set of details, you have your own answers.
