In a Penetrating Wound, ________ Divide to Produce Mobile Cells

Question

In a penetrating wound, ________ divide to produce mobile cells that repair the dermis.
A) granulation cells
B) dendritic cells
C) macrophages
D) fibroblasts
E) muscle cells

Accepted Answer

Fibroblasts are the cells responsible for repairing the dermis in a penetrating wound. They divide to produce mobile cells that migrate to the site of injury and produce collagen to form a scar. Granulation cells, dendritic cells, and macrophages are involved in other aspects of the immune response and do not directly contribute to dermal repair. Muscle cells are not found in the dermis.
