The document discusses the four main types of tissues in the body - epithelial, connective, muscle and nervous tissue. It provides details on the classification, structure and functions of each type of tissue. Epithelial tissues cover and line body surfaces. Connective tissues connect, support and bind other tissues. Muscle tissues contract to cause movement. Nervous tissues transmit electrical signals to coordinate body functions.

1. Groups of cells are similar in structure and function Classified by layers and shape Four types Epithelial Connective Muscle Nervous Tissues

2. Cellularity Special contacts Polarity Supported by connective tissue Avascular Regenerative Three types Simple epithelial Stratified epithelial Transitional

3. Transitional Epithelial Tissue  Cell layers  Stretchable

4. Simple Epithelial Tissue Single layer Three types Simple squamos Simple columnar Simple cuboidal

5. Simple Squamous Epithelial Single layer of flattened cells Disc shaped central nuclei Diffusion, Filtration Slick

6. Simple Columnar Epithelial Tissue Single layer Tall cells Oval nuclei Cilia

7. Simple Cuboidal Single Layer Cube like cells

8. Stratified Epithelial Tissue Several layers Three types Squamous Columnar Cuboidal

9. Stratified Squamous Epithelial Tissue Several layers Protective

10. Stratified Columnar Epithelial Tissue Limited distribution in body

11. Stratified Cuboidal Epithelial Rare Usually two layers thick Home / Stratified Squamos / Stratified Columnar / Stratified Epithelial Tissues / Epithelial Tissues

12. Connective Tissue Widely distributed in body Binds and Supports Protects and insulates Transports Mesenchyme Varying degrees of vascularity Cell types Fibroblasts Chondroblasts Osteoblasts Hemapoietic stem cells Four types Connective Tissue Proper Connective tissue Blood Connective Tissue Bone Connective Tissue Cartilage Home / Connective Tissue Proper / Blood / Bone / Cartilage

13. Connective Tissue Proper Fibroblasts Two Types Loose Dense Home / Loose / Dense / Blood / Bone / Cartilage / Connective Tissues

14. Loose Connective Tissue Proper Well vascularized Widely distributed throughout the body Wraps and cushions organs Two types Adipose Reticular Home / Adipose / Reticular / Loose Connective Tissue / Connective Tissue Proper / Connective Tissue

15. Adipose (fat) Loose Connective Tissue Proper A lot of ground substance High nutrient storing ability Adipocytes Nucleus on one side Richly vascularized Insulates Absorbs shock Stores energy Home / Reticular / Loose Connective Tissue / Connective Tissue proper / Connective Tissue

16. Reticular Loose Connective Tissue Proper Loose ground substance Reticular fibers Soft internal skeleton Home / Dense Regular Connective Tissue / Dense Irregular Loose Connective Tissue / Connective Tissue Proper / Connective Tissue

17. Dense Regular Connective Tissue Proper A lot of fibers Little ground space Parallel fibers Fibroblasts Muscle to Muscle, Muscle to bone, Bone to Bone Home / Dense Irregular Connective Tissue / Connective Tissue proper / Connective Tissue

18. Dense Irregular Connective Tissue Proper Irregular arangements of fibers Fibroblasts Expands in many directions Home / Dense Regular Connective Tissue Proper / Connective Tissue Proper / Connective Tissue

19. Cartilage Connective Tissue Chondrocytes Extracellular fibers Ground substance Three types Home / Hyaline Cartilage / Elastic Cartilage / Fibrocartilage / Connective Tissue

20. Hyaline Cartilage Connective Tissue Most abundant Supports Reinforces Cushions Resists Compression Home / Elastic Cartilage / Fibrocartilage / Cartilage / Connective Tissue

21. Elastic Cartilage Connective Tissue Many elastic fibers Maintains shape and structure Allows flexibility Home / Hyaline Cartilage / Fibrocartilage / Cartilage / Connective tissue
