In this video, Jonathan from the Institute of Human Anatomy uses real cadaver dissections to go layer-by-layer through the body, showing you the horrific reality of how deep damage can actually go all the way to muscle and bone. We’ll break down the classification systems (1st through 4th degree) and explain why a "painless" burn is often the most dangerous sign of all.
Watch as we step through the anatomy of the leg to reveal the "anatomical hotness" of the epidermis, dermis, hypodermis, and the deep fascia that protects your muscles.

❓ Common Questions
Why is the skin red in a first-degree burn if the top layer has no blood?
The redness comes from vasodilation in the dermis layer underneath responding to the damage.
Are third-degree burns less painful than second-degree?
Counterintuitively, yes—in the center—because the nerve endings that send pain signals are completely destroyed.
What is an eschar?
It is a thick, dry, leathery layer of dead tissue that forms in severe third-degree burns.
Can you skin graft a fourth-degree burn?
Often no, because grafts cannot replace destroyed fascia, muscle, or ligaments.
What makes electrical burns unique?
The current can travel deep into the body, affecting internal organs and the heart’s rhythm.
