A&P Unit 3 – Histology Cover Sheet A tissue is a group of cells with similar specialized structures which carry out specific functions. Tissues that perform different functions have very different structures. Use these statements to guide your learning and studying in this unit: 1. Define all vocabulary words. (BLM 1) 2. Describe the germ tissue layers, their location, and what tissues they produce in eucoelomate animals (humans). (BLM 2) 3. Distinguish between the apical surface, basal surface and basement membrane for a tissue. (BLM 2) 4. Describe the general locations, functions and characteristics of epithelial tissues. (BLM 1, 2) 5. Classify and name epithelial tissues according to shape and number of layers. (BLM 4) 6. Draw various examples of classes of epithelial tissues. (BLM 3) 7. Describe the location, function and unique characteristics of various epithelial tissues. Relate structure to function for each. (BLM 1-4) (Simple Squamous, Simple cuboidal, Simple Columnar, Stratified Squamous - Nonkeratinized, Keratinized, Pseudostratified columnar, Stratified transitional, Glandular) 8. Explain what it means for a tissue to be “keratinized”. Why are some epithelial tissues keratinized and some not? State location where a keratinized tissue would be appropriate and one where it would not. (BLM 2, 3) 9. Explain what it means for a tissue to be avascular. What sorts of tissues are avascular? Determine the potential challenges this presents for the cells that make up that tissue. (BLM 1-4) 10. Epithelial tissues often have active germ layers. Explain the purpose of a germ layer. Why do epithelial tissues benefit from their germ layers? (BLM 1-4) 11. Explain the difference between simple and stratified epithelial tissues. List two locations in the body where each is found. Suggest why each type of tissue makes sense for each location. (BLM 1-5) 12. Describe the general locations, functions and characteristics of connective tissues. (BLM 1, 2) 13. Explain why connective tissues take a long time to heal when damaged. (BLM 2) 14. Explain the function of a fibroblast cell. (BLM 2) 15. Compare and contrast loose and dense connective tissue. State one function/location for each, and explain why this type of tissue is appropriate for that location. (BLM 1-4) 16. Compare and contrast regular and irregular connective tissues in terms of fiber arrangement, tissue strength and function. State one function/location for each, and explain why this type of tissue is appropriate for that location (BLM 1-3) 17. Create a T chart to compare and contrast Hyaline cartilage, Elastic cartilage and Fibrocartilage. (BLM 4) 18. Explain why blood is considered a connective tissue. (BLM 4) 19. Contrast osteoblasts and osteoclasts. (BLM 2,3) 20. Describe the location, function and unique characteristics of various connective tissues. Relate structure to function for each. (BLM 1-4) (Loose irregular, Loose reticular, Adipose, Dense regular, Dense irregular, Hyaline cartilage, Elastic cartilage, Fibrocartilage, Bone, Blood) 21. Create a 3-way T chart to compare and contrast skeletal, smooth and cardiac muscle. Include locations, functions, structures and special characteristics. (BLM 1, 2) 22. Describe the general locations, functions and characteristics of nervous tissues.
