Anatomy Kyle

  1. 1. Tissues <ul><li>A group of cells similar in structure and function </li></ul><ul><li>Work together to perform a common function </li></ul>Epithelial Connective Muscle Nervous
  2. 2. Epithelial Tissue <ul><li>Composed mostly of cells </li></ul><ul><li>Classified by number of layers and shape </li></ul><ul><li>Regenerative </li></ul>Simple Stratified Other Epithelial Tissue
  3. 3. Simple Epithelial <ul><li>A single layer of cells </li></ul><ul><li>Typically found where absorption and filtration occur </li></ul><ul><li>3 types </li></ul>Squamous Columnar Cuboidal Epithelial Tissue Simple Epithelial
  4. 4. Simple Squamous <ul><li>A single layer of flattened cells </li></ul><ul><li>Provide diffusion and filtration </li></ul><ul><li>Provide slick lining </li></ul>Simple Epithelial
  5. 5. Simple Cuboidal <ul><li>Shape is cube-like </li></ul><ul><li>Large, spherical central nuclei </li></ul><ul><li>Function in secretion and absorption </li></ul>Simple Epithelial
  6. 6. Simple Columnar <ul><li>Tall cells </li></ul><ul><li>Function in absorption and secretion </li></ul><ul><li>Ciliated and non-ciliated types </li></ul>Simple Epithelial
  7. 7. Stratified Epithelial <ul><li>Epithelial tissue with multiple layers of cells </li></ul>Squamous Columnar/Cuboidal Epithelial Tissue Stratified Epithelial
  8. 8. Stratified Squamous <ul><li>Forms a thick membrane </li></ul><ul><li>Protection for areas subject to abrasion </li></ul>Stratified Epithelial
  9. 9. Stratified Columnar/Cuboidal <ul><li>Rare/limited distribution </li></ul><ul><li>Highly specific functions </li></ul>Stratified Epithelial
  10. 10. Other Epithelial <ul><li>Transitional, Pseudostratified, Glandular </li></ul>Pseudostratifed Columnar Transitional Glandular Epithelial Tissue Other Epithelial
  11. 11. Transitional <ul><li>Several cell layers </li></ul><ul><li>Basal side is formed of cuboidal cells, surface cells are dome-shaped </li></ul><ul><li>stretches </li></ul>Other Epithelial
  12. 12. Pseudostratified Columnar <ul><li>Single layer of cells with nuclei at differing heights </li></ul><ul><li>Creates illusion of being stratified </li></ul><ul><li>Function in secretion and absorption </li></ul>Other Epithelial
  13. 13. Glandular <ul><li>One or more cells that work together to make and secrete an aqueous liquid </li></ul>Endocrine Exocrine Other Epithelial Glandular
  14. 14. Endocrine <ul><li>Ductless glands </li></ul><ul><li>Produces hormones </li></ul>Glandular
  15. 15. Exocrine <ul><li>Secrete fluids onto body surface </li></ul><ul><li>More numerous than endocrine </li></ul>Glandular
  16. 16. Connective Tissue <ul><li>Most abundant and widely distributed tissue found throughout body </li></ul><ul><li>Formed from fibers and cells </li></ul><ul><li>Four variations </li></ul>Connective Tissue Proper Cartilage Blood Bone
  17. 17. Connective Tissue Proper <ul><li>All mature connective tissues except bone, cartilage, and blood </li></ul><ul><li>Loose and Dense forms </li></ul>Loose Dense Connective Tissue Connective Tissue Proper
  18. 18. Loose <ul><li>Areolar, Adipose, and Reticular </li></ul>Areolar Adipose Reticular Connective Tissue Proper Loose
  19. 19. Areolar <ul><li>A gel-like matrix with all 3 fiber types, macrophages, mast cells, fibroblasts, and some white blood cells </li></ul><ul><li>Wraps and cushions most organs </li></ul><ul><li>Widely distributed </li></ul>Loose
  20. 20. Adipose <ul><li>Similar to areolar </li></ul><ul><li>Fatty </li></ul><ul><li>Reserves food stores (fat), insulates, supports and protects </li></ul><ul><li>Heavily vascularized </li></ul>Loose
  21. 21. Reticular <ul><li>Network of reticular fibers with reticular cells </li></ul><ul><li>Forms a soft internal skeleton (stroma) </li></ul>Loose Photo by Akay(Creative Commons)
  22. 22. Dense <ul><li>Regular and Irregular </li></ul>Connective Tissue Proper Regular Irregular Dense
  23. 23. Regular <ul><li>Consists of parallel collagen fibers with few elastic fibers and fibroblasts </li></ul><ul><li>Connects muscle to muscle, muscle to bone, and bone to bone </li></ul>Dense
  24. 24. Irregular <ul><li>Irregularly arranged collagen with some elastic fibers </li></ul><ul><li>Fibroblasts </li></ul><ul><li>Can withstand tension in multiple directions </li></ul>Dense
  25. 25. Cartilage <ul><li>Hyaline, Elastic, and Fibrocartilage </li></ul>Connective Tissue Hyaline Elastic Fibrocartilage Cartilage Cartilage
  26. 26. Hyaline <ul><li>An amorphous, firm matrix of collagen fibers </li></ul><ul><li>Supports, reinforces, cushion, resists compression </li></ul>Cartilage Photo by Creative Commons
  27. 27. Elastic <ul><li>Similar to hyaline but more flexible </li></ul><ul><li>Can maintain shape and structure under stress </li></ul>Cartilage
  28. 28. Fibrocartilage <ul><li>Similar to hyaline but less firm </li></ul><ul><li>Functions in providing tensile strength and absorption of compressive shocks </li></ul>Cartilage
  29. 29. Bone <ul><li>A hard calcified matrix of collagen fibers </li></ul><ul><li>Supports, protects, provides levers for muscular action </li></ul><ul><li>Stores calcium, minerals, and fat </li></ul><ul><li>Marrow in bone is site of hemotopoiesis </li></ul>Connective Tissue
  30. 30. Blood <ul><li>Consists of red and white blood cells in a fluid matrix (plasma) </li></ul><ul><li>Transports respiratory gasses, nutrients, wastes </li></ul>Connective Tissue
