1. TISSUES NOTES PART 1

3. Learning Objectives  Identify the four major tissue types and describe their functions.  Describe the relationship between form and function for each tissue type.  Describe the three types of muscle tissue and the structural features of each.  Discuss the basic structure and role of neural tissue.

4. NOTES - TISSUES The human body is organized in the following manner: ATOMS MOLECULES CELLS TISSUES ORGANS ORGAN SYSTEMS ORGANISM (human)

6. TISSUE (definition) similar cells with the same function 4 types of human tissue: Histology = study of tissues I. EPITHELIAL TISSUE II. CONNECTIVE TISSUE IV. NERVOUS TISSUE III. MUSCLE TISSUE Ed Copies Mrs. Notes

7. Epithelial  General Characteristics:  -Main glandular tissue (glands)  Cells reproduce rapidly  Cells tightly packed together  Attached to underlying connective tissue by noncellular nonliving basement membrane

8. I. EPITHELIAL TISSUE Function: cover or lining of organs

9. Function Continued  1. protection  2. Secretion  3.Absorption  4. Excretion  5. Sensory Perception

11. Simple Squamous  Location: heart and blood vessels, exchange surfaces of lungs  Function: reduces friction, controls vessel permeability

13. Simple Cuboidal  Function: limited protection, performs absorption and secretion  Location: glands, ducts, kidney tubules

15. Simple Columnar Epithelium long rectangles packed close together Function: to secrete chemicals & absorb nutrients Location: lining of digestive tract (stomach, intestines)

16. Stratified Squamous Epithelium Function: protection from injury cells on the bottom are round – they become flat near the top Location: skin

17. 3. Ciliated Epithelium (aka: psuedostratified) similar to columnar epithelium, but with CILIA Function: movement of mucus or egg by action of cilia, nasal cavity, trachea and bronchi Location: oviducts (fallopian tubes) * there are other types of epithelium as well

18. Tracheal epithelium (ciliated)

19. Transitional Epithelium  Location: urinary bladder  Function: permit expansion and recoil after stretching

22. TISSUES NOTES PART 2

23. Part 2: Connective Tissue  General Characteristics: -Most abundant tissue in your body, found throughout -Binds structures together -Provides support, protection, framework, fills space, stores fat, produces blood cells, fights infection, and helps repair tissue.

24. 4 common Types of Cells  1. mast cells (prevents blood clots) 2. macrophages (phagocytic ) Big Eater 3. fibroblasts (most abundant, produce fibers)  4. Fat Cells (adipose cells)

25. Loose Connective  Areolar: binds skin to underlying organs and organs to organs, space between muscles, throughout body

26. Loose Connective  ADIPOSE TISSUE - aka FAT, beneath skin, around kidneys and eyeballs, abdominal membranes. Function: Protective cushion, insulation to preserve body heat, stores energy, cells are called adipocytes

27. Dense Connective Tissues  dense tissue, closely packed, thick collagenous fibers and fine network of elastic fibers. Few cells, poor blood supply, thus slow healing.  Example?

29.  Tendon =  Ligament =

30. Fluid  Types  1. Blood  2.Lymph

31. Blood Break

32. Supporting  1. Bone  2. Cartilage

33. Function of Bone and Cartilage  Cartilage and bone support the rest of the body

34. Cartilage Types:  1. Hyaline: most common  2. Elastic: external ear, epiglottis  3. Fibrocartilage: vertebrae of spinal column, pubic bones of pelvis
