body Cells in an extracellular matrix Has collagen and ground substance 2 Collagen is the main structural protein that is found in the extracellular spaces in connective tissues and it is also the most abundant protein found in the body 3 What is a fibroblast A fibroblast is the most common cell that makes collagen 4 Match the term with the definition Interstitial C relating to spaces within a tissue or organ but not body cavities Stroma E the framework of an organ or gland Usually made of connective tissue Parenchyma A cells or tissue of an organ that fulfill its functional role Adventitia B outermost connective tissue covering of an organ or vessel Serosa F epithelial lining of a body cavity secretes lubricating fluid Lumen D the cavity of an organ 5 Name the types of Connective Tissue Proper Loose Areolar Adipose Reticular 6 Name the types of Connective Tissue Proper Dense Regular Irregular Elastic 7 What is the difference between fixed cells and wandering cells Fixed Cells cells that develop and remain within connective tissues Examples are Fibroblasts Fixed macrophages Adipocytes Mesenchymal Cells Melanocytes Wandering Cells cells that are found in connective tissue but DO NOT stay in the same location Examples are Free Macrophages Mast cells Lymphocytes Microcytes BY 115 Human Anatomy SI Faith Leonard fkaylene uab edu 256 841 2663 8 Label the picture 9 Name the following tissues function Adipose Tissue important in padding insulation and energy storage Reticular Tissue provides supporting framework for non muscular visceral organs 10 Name the location of each type of tissue Dense Regular CT between skeletal muscles and tendons aponeuroses between bones ligaments covering skeletal muscles deep fasciae Dense Irregular CT capsules of visceral organs dermis layer of the skin periosteum and perichondrium nerve and muscle sheaths Elastic CT between vertebrae of the spinal column ligaments supporting the penis underlying transitional epithelia in walls of blood vessels BY 115 Human Anatomy SI Faith Leonard fkaylene uab edu 256 841 2663 11 Name the function of each type of tissue Dense Regular CT provides firm attachment conducts pull of muscles reduces friction between muscles stabilizes position of bone Dense Irregular CT provides strength to resist force helps prevent overexpansion of organs ex urinary bladder Elastic CT stabilize positions of vertebrae and penis cushions allows expansion and recoil of organs 12 How is connective tissue different from epithelial tissue Connective Tissue made up of the cell and a huge amount of intercellular matrix support and anchors other tissue and organs helps in muscles and bone formation also helps in working of blood and lymph the arrangement of cells are in a scattered form in the matrix cells are enclosed by blood capillaries lie below the basement membrane can be found in bones nerves ligaments tendons blood bound by blood capillaries elastin or collagen fibers Epithelial Tissue made up of the cell and a small amount of intercellular matrix mainly form a covering of the organs internally as well externally helps in transcellular or intercellular transportation in selective absorption and in the protection of cells the arrangement of cells is either single or multilayer are not enclosed by blood capillaries lie above the basement membrane bound by special proteins desmosomes and hemidesmosomes can be found in lungs kidneys skin mucous membranes BY 115 Human Anatomy SI Faith Leonard fkaylene uab edu 256 841 2663 Multiple Choice Questions 1 Functions of connective tissue include A establishing a structural framework for the body B transporting fluid and dissolved materials from one body region to another C protecting delicate organs D supporting surrounding and interconnecting other tissue types E All of the answers are correct 2 Which of the following cells can be found in connective tissue A mesenchymal cells B All of the answers are correct C eosinophils D mast cells 3 What is the most abundant type of tissue A Nervous B Muscular C Epithelium D Connective E None of these 4 What is the most abundant protein in mammals A Collagen B Hemoglobin C Keratin D None of the above 5 Loose connective tissue proper contains A fixed and wandering cells B a tight framework C parallel packed fibers D a solid ground substance BY 115 Human Anatomy SI Faith Leonard fkaylene uab edu 256 841 2663 6 Most energy storage in the body is accomplished by which of the following cells A macrophages B melanocytes C adipocytes D fibroblasts E lymphocytes 7 Small mobile connective tissue cells that release chemicals after injury or infection which stimulate the inflammatory response are known as A lymphocytes B adipocytes C microphages D free macrophages E mast cells 8 Extracellular fibers and comprise the matrix that surrounds the cells of a connective tissue A melanocytes B ground substance C fibroblasts D mesenchymal cells E neutrophils and eosinophils 9 Liposuction is a surgical procedure for reducing subcutaneous tissue A adipose B areolar connective C reticular D fibrous cartilage E dense regular connective BY 115 Human Anatomy SI Faith Leonard fkaylene uab edu 256 841 2663 10 The relatively few residing in connective tissues engulf damaged or dead cells or invading pathogens and release chemicals that attract many more cells to activate the immune system A mast cells B mesenchymal cells C fibrocytes D fixed macrophages E monocytes 11 When a local injury or infection damages or destroys connective tissues the respond by dividing to produce daughter cells that differentiate into fibroblasts or other connective tissue cells A resting macrophages B fibrocytes C mucoid connective tissue D mesenchymal cells 12 tissue provides a supporting framework of the liver spleen bone marrow and lymph nodes A Dense irregular B Areolar C Adipose D Elastic E Reticular 13 Membranes are formed by the combination of which tissues A epithelial and connective B epithelial and muscle C connective and muscle D muscle and neural E connective and neural BY 115 Human Anatomy SI Faith Leonard fkaylene uab edu 256 841
