BIOB33H3 Lecture Notes - Lecture 4: Elastic Cartilage, Elastic Fiber, Subcutaneous Tissue
Document Summary
Most diverse, abundant, widely distributed and microscopically variable. Examples: bone, cartilage, blood, connective tissue proper ligament, tendon, fibrous tissue, loose connective tissue, dense connective tissue, fat. Physical protection bones of cranium, sternum, vertebral column, thoracic cavity, fat surrounding organs. Transporting fluid and dissolved materials blood carries nutrients, gases, hormones, wastes and blood cells between different regions of the body. Connecting other tissues ligaments bind bone to bone; tendons bind muscle to bone; dense irregular tissue (fascia) binds skin to underlying muscle and bone. Storing energy fat is major energy reserve in the body, bones are a large reservoir for calcium and phosphorus. Matrix is the collective term for the extracellular component of any connective tissue that is made of protein fibers and the ground substance. Ecm is secreted from cells of connective tissue by proteins in fibrous tissues called fibroblasts. Terminology - ______cyte a generic cell type (eg. osteocyte in bone, adipocyte in fat)
