Final answer:
An embalming instrument for injecting chemicals into the body is known as an embalming injection device or hypodermic embalming needle, which introduced embalming chemicals such as formaldehyde to preserve the body.
Step-by-step explanation:
An embalming instrument used to hypodermically inject areas of the body with embalming chemicals is commonly known as an embalming injection device or a hypodermic embalming needle. These precision instruments allow embalmers to introduce formaldehyde-based fluids, or other embalming chemicals, directly into specific areas to achieve disinfection and preservation, which is essential in the process of embalming.
This is similar to other types of injections, such as the anesthetics administered for surgical procedures, yet the substances and intended outcomes differ greatly. While anesthetics like propofol or benzodiazepines are used to induce a reversible unconscious state for surgery, embalming chemicals like formaldehyde are utilized to permanently preserve tissue by halting biological processes and preventing decay.
