Loose (3) A. Collagen Fibers A. Reticular Fibers A. Elastic Fibers B. Dense Irregular Connective Tissue Connective Tissue C. Dense Regular Connective Tissue Tissue • Connective Tissue Proper (cont.) – Tendon: regular connective tissue; attach muscle to bone – Ligaments: regular connective tissue; connects bones and cartilage's 2) Cartilage: – rigid consistency, flexibility, slight elasticity – form resistant to pressure (unlike CTP) – composed of matrix (cytoplasm) – 3 types: Hyaline, Elastic, Fibrous Cartilage Fibrous Hyaline Elastic
