Partial-thickness wounds heal primarily by which process?

Explanation:
Partial-thickness wounds heal mainly by regeneration because the injury affects the epidermis (and possibly the superficial dermis) while the deeper regenerative structures are still present. Basal keratinocytes at the wound edges, along with cells from hair follicles and sweat glands, proliferate and migrate to reseal the surface, restoring the epidermal barrier with tissue that closely resembles the original. This re-epithelialization leads to minimal scarring. Neovascularization supports healing by bringing blood supply but is not the primary process in these wounds. Calcification is not a typical part of wound healing.
