Connective Tissue |
Most abundant and widely distributed in the body. |
|
|
Connective Tissue Function |
-Bind, supports and strengthens other tissue. -Protects organs, separates structure, stores energy in fat tissue. -Main source of immune response |
|
|
Connective Tissue Features |
-Composed of cells separated by Extracellular Matrix that consists of ground substances and fibers. -Has rich blood and nerve supply. |
|
|
Connective Tissue Characteristics |
-Derived from Mesenchyme. |
|
|
Immature Connective Tissue Cells |
-they end in -blast and retain the capacity for cell division and maintenance of the matrix is their role. -Fibroblasts, Chondroblasts, and Osteoblasts. |
|
|
Fibroblasts |
-Found in loose cartilage and dense C.T. -Most numerous and secrete fibers as they migrate and ground substance. |
|
|
Chondroblasts |
Found in cartilage |
|
|
Osteoblasts |
Found in Bone |
|
|
Marcrophages |
-From monocyte white blood cells. -Engulf and detroy bacteria (phagocytosis). -2 types- Fixed in the lung and spleen and wandering macrophages move to sites of infection or inflammation. |
|
|
Plasma Cells |
-From white blood cells. -Secrete anibodies -Found in the G.I. tract and respiratory tracts |
|
|
Mast Cells |
-Found in blood cells of connective tissue. -Produce histamines which dilates small blood vessels for infection or inflammation. |
|
|
Adiopocytes |
-Fat (adipose) cells -Store triglycerides -Found deep in skin and around organs like heart and kidney. |
|
|
White Blood Cells |
-Not present in a large amounts in connective tisse. -May be present from blood in reponse to injury |
|
|
Mature Connective Tissue Cells |
Have a reduced capacity for cell division and end in -cyte |
