There are four main types of tissues in the human body: epithelial, connective, muscle, and nervous tissue. Epithelial tissues cover and line body surfaces, and can be simple or stratified. Connective tissues are found throughout the body and include bone, cartilage, blood, adipose, and fibrous tissues that connect and support other tissues. Muscle tissues include skeletal, smooth and cardiac muscle. Nervous tissues are made up of neurons and neuroglia and are responsible for processing and transmitting information.

1. Tissues Groups of cells that have similar functions and structures Epithelial Muscle Connective Nervous Align cells to cover and protect them Epithelial Connective Muscle Nervous Credits

2. Epithelial Classified by the number of layers Classified by shape Glandular Simple Stratified Home

3. Glandular Endocrine glands Exocrine glands Most common types of epithelia Epithelial Home

4. Simple Consist of one layer of cells Covering epithelia Lining epithelia Pseudostratified Squamous Cuboidal Columnar epithelia home

5. Pseudostratified Actually a simple columnar epithelium Gives the false appearance of being stratified Is often ciliated Simple Epithelial Home

6. Squamous A classification of epithelium Depends on shape Simple Epithelial Home

7. Cuboidal A classification of epithelium Depends on shape Simple Epithelial Home

8. Columnar A classification of epithelium Depends on shape Can be nonciliated Can be ciliated Simple Epithelial Home

9. Stratified Consists of two or more layers of epithelial cells Covering epithelia Lining epithelia Transitional Squamous Cuboidal/Columnar Epithelial Home

10. Transitional Stratified squamous epithelium Has rounded cells Has the ability for cells to slide over one another to stretch an organ Stratified Epithelial Home

11. Squamous Classified based on shape Non-keratinized Keratinized Stratified Epithelial Home

12. Cuboidal/Columnar Classification of epithelium depending on shape Not common in the body Stratified Epithelial Home

13. Connective Tissues Found in all parts of the body Most abundant and widely distributed of tissues Most have a large amount of blood vessels Composed of many types of cells Made up of noncellular and nonliving material called a matrix Proper Cartilage Bone Blood Home

14. Cartilage Cartilage protects bones Cartilage helps form bones Found in the knees, ears, and nose Hyaline Elastic Fibrocartilage Connective Home

15. Hyaline Has chondrocytes in lacunae Found in: Embryonic skeleton The end of long bones Nose Trachea larynx Cartilage Connective Home

16. Elastic Cartilage Connective Home Maintains shape Maintains structure Allows flexibility

17. Fibrocartilage Cartilage Connective Home Provides tensile strength Absorbs compression shock

18. Bone Proper Dense Connective Home Stores calcium Stores minerals Stores fat Marrow inside of bones is the site of hematopoiesis

19. Proper Loose Areolar Adipose Reticular Bone Connective Home Embryonic Includes: Areolar Adipose Reticular Dense fibrous connective tissues

20. Loose Bone Connective Home Areolar Adipose Reticular Fat storage

21. Areolar Bone Connective Home Considered the prototype of the connective tissues All other connective tissues are based off of the structure of the areolar connective tissues

22. Adipose Bone Connective Home Fat tissues Insulates the body Stores food for the body

23. Reticular Bone Connective Home Loose ground substance Forms a soft internal skeleton Resembles fibroblasts Supports many free blood cells in lymph nodes, the spleen, and bone marrow

24. Dense Regular Irregular Elastic Bone Connective Home Often referred to as dense fibrous connective tissues Fibroblasts Includes: Regular fibers Irregular fibers Elastic fibers

25. Regular Bone Connective Home Fibroblasts Found in tendons Ligaments Aponeuroses

26. Irregular Bone Connective Home Fibroblasts Found in dermis Sub mucosa of the digestive tract Fibrous organ capsules

27. Elastic Bone Connective Home Combine strength with elasticity Dense fibrous tissues Occurs in regular and irregular connective tissues

28. Blood Connective Home Closed circulatory system in humans Open circulatory system in other animals

29. Muscle Voluntary Involuntary Home Produces most types of body movements Three main types of subcategories of muscle tissues are: Cardiac Skeletal smooth

30. Voluntary Skeletal Muscle Home Movements of the body Consciously controlled Striated

31. Skeletal Muscle Home Flesh of the body Attached to the skeleton

32. Involuntary Smooth Cardiac Muscle Home Unconsciously controlled movements of the body Happens without humans being aware

33. Smooth Muscle Home Mainly found in the walls of hollow organs Normally two layers that run perpendicular to each other

34. Cardiac Muscle Home Found only in the heart Has intercalated discs

35. Nervous Neurons Home Neuroglia Neurons Most associated with nervous system functioning

36. Neurons Sensitive Highly specialized Receives and sends stimuli to the brain and the whole body Nervous Home
