What is required for the mechanical setting of features during embalming?

The mechanical setting of features during embalming involves the use of instruments or sutures to properly position and secure facial features in a natural and aesthetically pleasing appearance. This technique ensures that the deceased looks peaceful and lifelike, which is crucial for viewing by family and friends.

Using instruments, such as embalming needles or forceps, allows the embalmer to adjust the position of the eyes, mouth, and other facial features. Sutures can be utilized to keep the mouth closed or to create the desired shape of the features. This process reflects an understanding of human anatomy and is part of the preparation that enhances the dignity of the deceased in their final presentation.

The other options, while relevant to the embalming process, do not pertain specifically to the mechanical setting of features. Injecting solutions primarily relates to the preservation and disinfection of the body rather than positioning features. Cooling techniques might involve the management of body temperature to slow decomposition but do not assist in feature positioning. Natural preservation typically refers to processes that occur without intervention or with minimal treatment, which again does not address the mechanical aspects of setting features.
