ignorence of the human body is the surgoens cardinal sin, sirs!

For a surgeon, it was absolutely imperative for him to be intimately aware of the physiognomy of the human body. Ignorance of the human body was the surgeon's cardinal sin because his work was related to it. To operate without as complete knowledge of the body as if the surgeon himself had made it was the prerequisite. If the surgeon did not possess such knowledge then according to Sadao's old American professor of anatomy, it would be tantamount to murder. A surgeon had to be familiar with every atom of the human body.
