GENERAL HISTOLOGY

Detailed explanation-1: -Second-degree burns involve the epidermis and part of the lower layer of skin, the dermis. The burn site looks red, blistered, and may be swollen and painful.

Detailed explanation-2: -A third-degree burn is extremely serious; the entire thickness of the skin is destroyed, along with deeper structures such as muscles. Because the nerve endings are destroyed in such burns, the wound is surprisingly painless in the areas of worst involvement.

Detailed explanation-3: -First-degree burns affect only the outer layer of the skin. They cause pain, redness, and swelling. Second-degree burns affect both the outer and underlying layer of skin. They cause pain, redness, swelling, and blistering. Third-degree burns affect the deep layers of skin. 31-May-2022
