Study Notes
Connective Tissue
- Connective tissue is derived from mesoderm.
- The function of connective tissue is to provide support, structure, and connectivity to the body.
Extracellular Matrix
- The extracellular matrix is made of ground substance, fibers, and cells.
- The ground substance is composed of proteoglycan molecules, hyaluronic acid, and chondroitin sulfate.
- Fibers in the extracellular matrix include collagen, elastin, and fibrillin.
Connective Tissue Cells
- Cells derived from mesenchyme include fibroblasts, adipocytes, chondrocytes, osteocytes, and odontoblasts.
- Cell types with names that end in -cyte include fibrocyte, adipocyte, chondrocyte, osteocyte, and odontoblast.
- Principal active cells of connective tissue include fibroblasts, macrophages, and mast cells.
- Fibroblasts are modified to form myofibroblasts, which can contract and secrete collagen.
- Pluripotent cells in the bone marrow include macrophages, plasma cells, mast cells, neutrophils, and eosinophils.
Connective Tissue Types
- Connective tissue with a gel-like consistency includes areolar tissue and mesenchyme.
- Connective tissue with a good nerve and blood supply, except in cartilage and tendons, includes loose and dense connective tissue.
- Adipose tissue stores triglycerides and is found beneath the skin and around internal organs.
- The main function of adipose tissue is to store energy.
Collagen
- Collagen type I forms fibers in the skin, bones, tendons, and ligaments.
- Collagen type IV forms networks in the basal lamina.
- Collagen type VII is associated with fibrils and anchors the basement membrane to the epidermis.
- The function of collagen is to provide strength, structure, and support to the extracellular matrix.
Other Components
- Elastin and fibrillin provide elasticity to the extracellular matrix.
- Proteoglycan molecules capture water, provide lubrication, and maintain tissue shape.
- Hyaluronic acid captures water, turning the ground substance into a jelly-like texture, and brings cells together.
- Chondroitin sulfate provides support and adhesiveness to cartilage, bone, skin, and blood vessels.
