NEET PG DENTAL EXAM

Detailed explanation-1: -Fibrocytes, or fibroblasts and fat cells(adipocytes) are fixed cells, where as macrophages, monocytes, lymphocytes, plasma cells, eosinophils and mast cells are wandering cells.

Detailed explanation-2: -Fibroblasts, adipocytes (fat cells), macrophages, and mast cells are regarded as resident cells. Transient cells (or wandering cells)-leukocytes (white blood cells) that migrate from the bloodstream into connective tissue in response to a signal (e.g., inflammation or tissue damage).

Detailed explanation-3: -Neutrophils are highly motile phagocytic cells that constitute the first line of defense of the innate immune system. They were first discovered by Elie Metchnikoff when he inserted rose thorns into starfish larvae and found that wandering mesodermal cells accumulated at the puncture site.

Detailed explanation-4: -The cells can be separated into two groups, resident and transient. Resident cells, such as fibroblasts, myofibroblasts, adipocytes and certain immune cells are always present in connective tissue. Their main roles is to secrete, maintain, recycle, repair and protect the ECM and surrounding tissue structures.
