Why is rigor mortis harmful to the embalming process?

• A. It promotes bacterial growth
• B. It creates an extrinsic vascular blockage
• C. It prevents fluid distribution
• D. It accelerates decomposition

Answer: (B)

Rigor mortis occurs after death when the muscles stiffen due to biochemical changes in the body. The main reason rigor mortis is harmful to the embalming process is that it creates an extrinsic vascular blockage. When the muscles become stiff, it can constrict blood vessels, making it more challenging for embalming fluids to flow throughout the body. This constriction can limit the distribution of the embalming chemicals, which are essential for preserving the tissues and preventing decomposition.

The significance of proper fluid distribution cannot be overstated; it is crucial for effectively embalming all areas of the body to ensure uniform preservation and prevention of any potential issues post-embalming. Successful embalming relies on the ability to inject fluids that will reach all tissues, and rigor mortis hinders this process. Therefore, understanding the impact of rigor mortis on vascular blockage is essential for mortuary science practitioners.
