Study Guide for Week 3 1 1 Epithelial Tissues covers surfaces lines cavities ducts and forms glands 2 Connective Tissue supports and protects other tissues 3 Muscle Tissue causes movement amp heat 4 Nervous Tissue receives and generates nerve impulses 2 l To provide support strength elasticity and incompressibility l To provide environment for in ltration of immune cells D Important in defense in ammatory responses and tissue repair D Fibroblasts Adipocytes Mast Cells Plasma Cells and Macrophages Fibroblasts White blood cells Eosinophils amp Neutrophils Eosinophils are WBCs that migrate to sites of parasitic infection and allergic responses Neutrophils are WBCs that migrate to sites of infection that destroy microbes by phagocytosis ProteaoglycansGlycosaminoglycans Fibrillar Protein Fibers collagen elastin and reticular bers Glycoproteins bronectin and laminin Fibronectin adhesion protein that connects cells to ground substance Collagen fibers strong and resist pulling forces tension allowing exibility of tissue can be found in connective tissue such as bone cartilage tendons and ligaments Contain collagen protein Type 1 Collagen Reticular fibers provide support and strength in the walls of blood vessels and form a network around the cells in some tissues can be found in adipose tissue smooth muscle tissue connective tissueorgans amp basement m contain collagen protein Type 3 CoHagen Elastic fibers branch and join together to form a brous network within a tissue can be found in skin bladder blood vessel walls and lung tissue contain elastin and brillin protein GAGs Glyco sugar aminoglycan amino sugar ie repeating disaccharide of two sugars highly negative charged due to presence of sulfate groups disaccharide chains are unbranched and variable in length gellike consistency which allow to resist compressive forces These sugar chains are freq attached to core proteins to form proteoglycans Proteoglycans forms large aggregates with hyaluronic acid as backbone Negative charge makes them hydrophilic A watery environment facilitates movement of WBCs to reach infection and help penetrate of an oocyte by sperm cell during fertilization Allow rapid diffusion of watersoluble molecules through ecm watery environment where nutrients amp immune cells can migrate Resist compressive forces with gellike properties 1 Embryonic derived from an embryonic layer called mesenchyme 2 Mature Connective Tissue a Loose areolar CT adipose tissue reticular CT b Dense dense regular tendon CT dense irregular CT capsules of organs elastic CT wall of artery lung c Specialized CT cartilage bone blood 0 Cartilage Bone Blood Hyaline cartilage found on many joint surfaces articular surface of bones ribs nose larynx trachea Type 2 Collagen Elastic Cartilage yellow cartilage found in the ear external ear epiglottis and larynx Elastin Fibrocartilage found in intervertebral discs and meniscijoint capsules ligaments Type 1 Collagen Type 2 Collagen Articular cartilage belongs to hyaline cartilage articular cartilage found at end of long bones synovial joint Meniscal cartilage can be found at joint spaces Fibrocartilage is the strongest Elastic cartilage can be more easily exed Hyaline cartilage is best at resisting compressive forces 15 Look at the worksheet 16 Compact bone weight bearing bone that lays down a dense mineralized matrix Spongy bone also called trabecular or cancellous bone bone marrow runs through spongy bone 17 Platelets WBCs leukocytes RBCs erythrocytes Phagocytes are WBCs that engulf and absorb bacteria the neutrophils and eosinophils Platelets aid in clotting 18 Cardiac Muscle Tissue Branched Striated bers Involuntary Control Centrally Located Nuclei Founded in Heart Wall Pumps blood to all parts of the body Skeletal Muscle Tissue Long Striated Peripheral Nuclei Voluntary Control Usually attached to bones via tendons important in motion posture heat production and protection Smooth Muscle Tissue Spindle shaped nonstriated with centrally located nuclei involuntary control Walls of internal organs such as blood vessels GI tract airways to lungs Gall bladder urinary bladder uterus motion eg constriction of blood vessels movement of food through GI contraction of bladder uterus 19 1 Neurons nerve cells that convert stimuli into electrical signals called action potentials 2 Neuroglia cells that provide structural support to the neurons 20 When scar tissue is formed rather healthy tissue 21 Atrophy a decrease in size of cells with subsequent decrease in size of tissue Biopsy removal of a sample of living tissue for microscopic examination Hypertrophy increase in size of a tissue Tissue rejection immune rejection of a tissue Embryology H N lt LO 0 Fl D 2 1 Cleavage 2 Formation of morula 3 Formation of blastocyst The blastocyst implants into wall of uterus usually in the uterine tube 4 When pregnancy occurs outside the uterus Dangerous bc it may cause rupture of uterine tube Acute pain occurs after 1 or 2 missed periods 5 During the second week of development trophoblast produces human chorionic gonadotropin hCG 6 Ectoderm Mesoderm and Endoderm STEM CELLS 1 Bc they can develop into any cells 2 They become specialized 3 Pluripotent Stem Cells 4 Know that each tissue contains multipotent stem cells that retain the ability to divide in adult life The capacity for division varies according to the type of Ussue 5 You should know the mesenchymal stem cell lineage now We will study the hematopoietic cell lineage later in the course Mesenchvmal Stem Cells 1 Fibroblasts l Tendonligament 2 Osteoblasts from Osteogenesis Cells D Osteocytes D Bone 3 Chondroblasts D Chondrocytes D Cartilage 4 Myoblasts D Muscle cells 5 Adipocytes
