Why does scar tissue differ structurally from normal skin following a deep laceration, specifically regarding collagen arrangement?

A)Keratinocyte proliferation halts permanently
B)Sebum production increases dramatically
C)Collagen fibers align haphazardly
D)Melanin synthesis becomes highly regulated

💡 Explanation

Scar tissue forms due to rapid collagen deposition during wound repair; however, fibroblasts lay down collagen haphazardly, rather than in an organized lattice like normal skin, because of the speed of repair. Therefore, scar tissue has less tensile strength than normal skin, rather than controlled melanin production or keratinocyte malfunction.
