PDF-Connective Tissue Diseases

Edward D Buckingham MD Faculty Advisor Byron J Bailey MD The University of Texas Medical Branch Department of Otolaryngology Grand Rounds Presentation February 2000 Introduction xF06E col. Connective Tissue. 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. 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. The dense layer of the basal lamina of all epithelial tissue is created by connective tissue. . Connective tissue connects the epithelium to the rest of the body.. Three Basic Components. Specialized cells. Connective Tissue. Found everywhere in the body. Most abundant and widely distributed of the primary tissues. Major functions. :. Binding and support (bone and cartilage). Protection (bone and cartilage). Seema. . Zargar. Most diverse and abundant tissue. Main classes. Connective tissue proper. Cartilage. Bone tissue. Blood. Characteristics. Mesenchyme. as their common tissue of origin (. mesenchyme. 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) . 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. A. Connective Tissue General Characteristics. 1. . Connective tissues:. a. Bind. . b. Support. . c.

Found throughout the body but never exposed to the . external. environment.. Description. :. Made up of . specialized. cells.. Contains extracellular . A. General . Characteristics. 1. 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.. Zargar. Most diverse and abundant tissue. Main classes. Connective tissue proper. Cartilage. Bone tissue. Blood. Characteristics. Mesenchyme. as their common tissue of origin (. mesenchyme. derived from mesoderm). - 1 Four primary tissues of body — • Epithelial tissue • Connective tissue • Muscle tissue • Nervous tissue • connective tissue is one of most abundent and widely distributed tissue of 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 . -our second tissue type-. Text readings: chapter. 5. Connective Tissue. Lecture Outline. Function and Common Characteristics of all Connective Tissues. Connective Tissue Proper : its cells, fibers, and ground substance.
