Decomposition and complete muscle relaxation are which of the following?

Decomposition and complete muscle relaxation are which of the following?

• A. Signs of death
• B. Signs of life
• C. Livor mortis
• D. Rigor mortis

Answer: (A)

Decomposition and complete muscle relaxation are postmortem changes, meaning they occur after life has ended. Decomposition happens as tissues break down once circulation and metabolism stop. Right after death, muscles lose neural input and relax, so there’s a temporary state of relaxation before later changes like rigor mortis set in. Rigor mortis brings stiffness, not relaxation, so it wouldn’t describe the muscle state here. Signs of life would require current responses such as breathing, a pulse, or movement, which are absent when decomposition and relaxation occur. Livor mortis is another postmortem sign (blood settling and skin discoloration), but it doesn’t specifically address muscle state. So these changes point to signs of death.
