PPT-STRUCTURE AND FUNCTION OF BONE, JOINTS AND CONNECTIVE TISSUE

CLASSIFICATION OF JOINTS Human joints provide the structures by which bones join with one another and may be classified according to the histologic features of the union and the range of joint motion There are three classes of joint design. Page 81 - 85. Functions. Protection. Support. Binding together other body tissues. Characteristics. Most connective tissues are vascularized (have good blood supply). Ligaments and tendons are exceptions. 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. 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). CONNECTIVE TISSUE. Connective tissue is one of the basic tissues which gives structural and metabolic support to the organ and other tissue of the body.. It connects other tissues.. . 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. Dr Iram Tassaduq. ‘Connective tissue’ is the term traditionally applied to a basic type of tissue of mesodermal origin which provides structural and metabolic support for other tissues and organs throughout the body, also known as “Supporting tissue”.. Connect body parts, widely distributed. Functions. Protect, Support, Bind. Characteristics. Varied blood supply. Contain an extracellular matrix. Extracellular Matrix. Produced by connective tissues. 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. MMHS Anatomy. Location and Description. Location. :. Found throughout the body but never exposed to the . external. environment.. Description. :. Made up of . specialized. cells.. Contains extracellular . (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.. -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.
