Document Summary
4 types: connective tissue proper, cartilage, bone, blood. Main type, found in all ct, flexible but strong fibers. 4. elastic fibers stretch but return to original length when pressure released reticular strong, wire- like fibers that don"t stretch form framework of cells to hold shape of ct + gives cells attachment site. Cells fibroblasts or fibrocytes - make fibers in gags. Fibrocytes - found in already produced ct are amitotic (don"t divide, maintain matrix) cartilage - called chondrocytes bone- called osteocytes. Most widely distributed tissue around body functions: Has collagen fibers, some elastic fibers, few reticular fibers fluid matrix has a lot of hyaluronic acid. Brown fat - breakdown fat and give off energy as heat. Reticular ct reticular fibers form mesh for cells to attach seen in lymphnodes and spleen. The spleen processes tissue fluid or blood. Dense regular collagen fibers are parallel to each other forms ligaments and tendons. Very low blood supply - healing is long term.
