Debunking the Myth of Zombies

The video debunks the myth of zombies by explaining the stages of death, including pallor, algor, livor, and rigor mortis. It details how muscle contraction relies on calcium and ATP, which are unavailable after death, leading to rigor mortis. Autolysis eventually ends rigor mortis, but decomposition prevents any movement. The brain's need for oxygen and ATP further invalidates the possibility of zombie movement, as it shuts down quickly after death.

What is pallor mortis and how does it affect the appearance of the skin after death?

Explain the process of algor mortis and the factors that influence it.

How do environmental factors influence the decomposition process of a body?

Describe livor mortis and how it is affected by the position of the body after death.

What is rigor mortis and what physiological changes lead to its onset?

What role does calcium play in muscle contraction and how does it change after death?

How does the absence of ATP affect muscle contraction after death?

Discuss the process of autolysis and its impact on the body after death.

Why is the brain considered sensitive to oxygen deprivation, and what happens to it after death?

In what ways do the characteristics of a zombie contradict the biological processes discussed?
