1. Tissues Chapter 2 *You will need your notebook*

2. Tissues Groups of closely associated cells that are similar in structure and perform a common function Chapter 2: Cells and Tissues

3. Histology Histology = study of tissue

4. 1.epithelial 1.epithelial tissue–protection 2.connective 2.connective tissue–supports 3.muscle 3.muscle tissue–movement 4.nervous 4.nervous tissue–control Types of Tissues

5. squamous – flat cuboidal – square columnar – tall Epithelial Cell Shapes

6. simple – one layer stratified – more than one layer other – transitional stretchable Epithelial Cell Arrangement

9. Epithelial Glands = secrete substances

10. True or False? 1. Connective tissue provides support. 2. Transitional epithelial stretches. 3. Cuboidal cells are flat. 4. Stratified means more than one layer. 5. Epithelial glands secrete substances. Review True True False True True

11. functions – strengthens the body and organs – protects internal organs – maintains the shape of organs – provides rigid framework for muscles to pull fibers – collagen – reticular – elastic Connective Tissue

12. connective tissue proper connective tissue proper – wide variety of locations and functions – plays a role in immune defenses cartilage cartilage – provides support and flexibility – minimizes friction bone tissue bone tissue (osseous tissue) – provides framework, protects organs, supports body blood blood – provides transportation, regulation, and protection – carries oxygen and nutrients, and carbon dioxide Classes of Connective Tissue

13. connective tissue proper – loose – dense cartilage bone blood Types of Connective Tissue

15. loose connective tissue – areolar–under epithelium – reticular–spleen – adipose–fat Loose Connective Tissue

16. dense connective tissue – regular dense– tendons – irregular dense– dermis – dense elastic–large artery walls Dense Connective Tissue

17. chondroblasts hyaline – ends of long bones elastic – external ear fibrocartilage – intervertebral discs Cartilage

18. osseous tissue – protects organs – supports the body Bone

19. Skeletal – Attached to bones Cardiac – Found in heart smooth – Walls of hollow organs Types of Muscle Tissue

21. Glial cells (neuroglial) – nonconducting cells that support, insulate, and protect neurons. Neurons- generate and conduct nerve impulses. Nerve Tissue

22. Match the following with 1–4 below: skeletal, cartilage, nervous tissue, elastic cartilage. 1. muscle tissue type 2. external ear 3. fiber 4. glial cells Review and Assessment Skeletal Elastic cartilage Cartilage Nervous tissue
