PPT-Extracellular Matrix Animal tissue is not only composed of cells but also contains many

The macromolecules that constitute the extracellular matrix are mainly secreted locally by the cells In most of the connective tissues the macromolecules are secreted by fibroblast Fig 49 In some . KEEPING THE BODY TOGETHER. Functions of connective tissue:. Interconnection of tissues. Support and motion. Storage. Cushioning and insulation. Enclosing and separating. Transport. protection. Characteristics of connective tissue. 2.3.1, 2.3.2: Liver cell. 2.3.3: Electron micrograph of liver cell (rat). Glycogen. 2.3.4: Prokaryotic VS Eukaryotic cell. FEATURE. Prokaryotic cell.

The extracellular matrix. What is it?. The extracellular matrix fills the spaces between cells and binds cells and tissues together. Types:. Cell Migration and Adhesion. Team Members. Marta Bechtel.

Larry Johnson. OBJECTIVES. 1. PREVIEW CELLULAR ULTRASTRUCTURE. 2. PREVIEW CELLS, TISSUES, AND ORGANS. 3. OVERVIEW OF LIGHT AND ELECTRON MICROSCOPY. PREPARATION OF SPECIMENS - TYPES OF VISIONS. Tissues. Four primary types of tissues:. Epithelial: cover body structures in order to absorb, secrete, protect, of filter materials in between layers of tissues.. Connective: support body structures.. Form metabolic and structural connections between other tissues… nutrition and support. Forms a protective sheath around organs and helps insulate the body…cushion. Acts as a reserve for energy…storage. Connect body parts, widely distributed. Functions. Protect, Support, Bind. Characteristics. Varied blood supply. Contain an extracellular matrix. Extracellular Matrix. Produced by connective tissues. 4-. 2. Tissue Level of Organization. The classification of tissue types is based on the structure of cells; the composition of noncellular substance surrounding cells (extracellular matrix) and the functions of the cells.. What cells hang out in CT?. Connective Tissue. Holding it all together! . Connective tissue is found everywhere! . Main types:. 1. Connective tissue . proper – . We will focus on this one most of next week!. The Basis of Physiological Regulation. Our bodies are made up of incredibly complex and delicate materials, and we are constantly subjected to all kinds of disturbances, yet we keep going for a lifetime. It is clear that conditions and processes in the body must be closely controlled and regulated, i.e., kept at appropriate values.. 2. . The ECM of animal cells • Animals cells lack the structure and support that a cell wall provides • Have an ECM instead that provides some of the same support. 3. . Components of the ECM • Cells secrete . synthetase in astrocytes (see Figure 10.13), glutamine isformed from glutamate. Glutamine is then uptaken byneurons and transformed back in glutamate.2.2OLIGODENDROCYTES FORM THE MYELIN SHEATHS OF AXO Functions:. Support. The bones of the legs, pelvic girdle, and vertebral column support the weight of the erect body.. The mandible (jawbone) supports the teeth.. Other bones support various organs and tissues..
