Which of the following substances is not typically used in the preparation of an autopsied body?

A wetting agent is not typically used in the preparation of an autopsied body. In the context of forensic science and pathology, the primary goal during the preparation of an autopsy is to preserve the body and its tissues for examination and analysis.

Formaldehyde, a commonly used preservative, helps to fix tissues and prevent decay, making it ideal for preserving biological samples. Alcohol can function as a disinfectant and preservative, helping to sanitize the area as well as preserve tissue samples. Glutaraldehyde is another preservative similar to formaldehyde but is often used for specific applications in biological and anatomical preparations because of its effectiveness in cross-linking proteins.

In contrast, a wetting agent is typically used for other purposes such as reducing surface tension in fluids, facilitating the spread of liquids, or improving cleaning efficacy in various applications. It does not play a significant role in bodily preservation in the context of an autopsy, which is why it is the correct focus here.
