CONNECTIVE TISSUE. I. t is a type of tissue that connect and support other body tissues, also called supporting tissue.. CLASSIFOCATION:. Classified on the basis of following four criteria. Relative proportion of various fibers. Connective Tissue Cells. Connective tissue proper . cells are usually divided into two groups based on their ability to move within the connective tissue. .. FIXED CELLS:. . Fibrocytes. (or fibroblasts) . Most . common. Well . supplied with blood. . . (tendons and ligaments) . Made . up of . many types of cells and . extracellular matrix. . Extracellular matrix. Produced by the connective tissue . cells. College. Objectives. What is connective tissue. Types of connective tissues. Functions of connective tissues. Relation of structure and function. Tissues . Four fundamental tissues are recognized:. Epithelial tissue. Connective Tissue - Recall. Epithelial Tissue (yesterday’s material). Basement Membrane. Connective Tissue. Three common types of cells found in connective tissue matrix:. 1. . Mast cells . – prevent blood clots. General Characteristics. Does have blood vessels- . variations in blood supply (ligaments and tendons don’t heal as fast because they are poorly vascularized). Cartilage is avascular –no blood supply- heals very slowly.

Connective tissues function to . bind structures, provide support and protect, serve as frameworks, fill spaces, store fat, produce blood cells, protect against infections, and help repair tissue damage..

Mesenchyme. as their common tissue of origin (. mesenchyme. derived from mesoderm). Zahiri. Formation of Type I collagen. Within . the cell. During translation, two types of peptide chains are formed on ribosomes along the . RER. (. the alpha-1 and alpha-2 . chains). These . peptide chains (known as . (cartilage and bone. ). Specialized Connective Tissue . * Include : Skeletal connective tissue (cartilage and bone).. skeletal connective tissue. :. Cartilage:. is a flexible connective tissue that keeps . Connective Tissue Lecture Objectives. List the functions of connective tissue. . Describe the structure, function, and appearance of collagen (types I, II, and III) and elastic fibers.. Explain what ground substance is and what it looks like..
