What type of tissue is primarily formed during the early stages of wound healing?

Granulation tissue is primarily formed during the early stages of wound healing. This type of tissue is essential in the healing process as it plays a critical role in filling the wound defect and providing a matrix for the migration of cells involved in healing. Granulation tissue consists of new connective tissue and tiny blood vessels that form on the surface of a wound, which is vital for supplying nutrients and oxygen that support healing.

The formation of granulation tissue marks a transition from the inflammatory phase of healing to the proliferative phase. It is characterized by the presence of fibroblasts, which produce collagen and extracellular matrix components, and new capillaries, which facilitate the transport of nutrients essential for repair.

Other types of tissues mentioned, such as muscle tissue, nerve tissue, and scar tissue, play different roles in the overall healing process. Muscle tissue is not directly involved in the early stages of wound healing, as its repair involves different mechanisms. Nerve tissue regeneration is a more complex process and usually occurs later, while scar tissue is the end product of healing that forms in the later stages after granulation tissue has served its purpose.
