Document Summary

*in the lab, all dense connective tissue will be irregular, except for tendon which is dense regular connective tissue. Components fibres are either collagen, reticular fibres or elastin cells present are either: connective tissue: fibroblast/fibrocyte responsible for making the, adipose cells fat cells, as seen in the hypodermis, macrophages, immunological cells. Ground substance is made of glycoproteins and proteoglycans. Made of collagen type i fibres and fibrocytes. In lab slides, fibres look wavy and all in same direction. *no slide for this: elastic in your ear lobes, hyaline most common type (ex. seen in trachea, articular at the tip of long bones cartilage is avascular (this limits its size) Perichondrium: dense irregular, covers all cartilage, except articular cartilage, two layers: connective tissue (type i collagen) fibrous layer, outer layer, made of fibrocytes and collagen type i. Chondrogenic layer inner layer: made of chondroblasts (flat, elongated cells) Ecm: produced by chondroblasts, collagen type ii, appositional from the perichondrium types of growth.
