Tissues: The Living Fabric

– Found between ribs and the sternum, trachea and articular surfaces of most joints• Elastic cartilage– Contains lots of elastic fibers– Found in the outer ear, epiglottis and larynx• Fibrocartilage– Densely packed with collagen– Very tough– Found between the vertebrae (intervertebral discs) and between the pubic bones (pubicsymphysis)– Covering and Lining Membranes• Membranes are formed by epithelial and connective tissues– Cutaneous membranes• Skin– Mucous membranes (mucosae)• GIT, respiratory, reproductive, urinary tracts– Serous membranes• Pleura, peritoneum and pericardium– Synovial membranes• Joints• Tissue Repair– Note that synovial membranes are NOT epithelial membranes and aresolely made up of connective tissue• Tissue injury results in body damage and increased susceptibility to pathogenic invasion• Tissue injury stimulates two major body responses– Inflammatory response– Immune response• Tissue Response• Inflammatory response
