  1. Animal Tissues

  2. I. Generalizations • A. Definition • B. Four general categories of animal tissue • 1. epithelial • 2. muscle • 3. nerve • 4. connective

  3. II. Epithelial tissueA. General Traits or characteristics • 1. found on a body surface either internal or external • 2. tightly packed cells • 3. free border or free surface • 4. rest on a basement membrane • 5. nonvascular

  4. B. Naming or classifying epithelial tissue • First Name a. Simple b. Stratified c. Pseudostratified • Second name a. Cuboidal b. Squamous c. Columnar

  5. C. Examples of naming • 1. simple cuboidal • 2. stratified squamous • 3. pseudostratified • 4. stratified cuboidal

  6. D. Specific examples • 1. stratified squamous • a. Location • b. function

  7. Examples continued • 2. transitional • a. Location • b. Function

  8. Examples continued • 3. simple cuboidal • a. Location • b. function

  9. III. Muscle tissue • A. General traits • 1. excitable tissue • 2. can shorten

  10. B. Types of muscle tissue • 1. skeletal muscle • a. multinucleate • b. voluntary • c. striated

  11. 2. Smooth muscle • a. Involuntary • b. Visceral • c. structure

  12. 3. Cardiac muscle-mixture of two • a. One nucleus/cell • b. Autorythmic • c. Striated • d. Intercalated disc

  13. IV. Nervous tissue • A. General Traits • 1. Irritable • 2. Conductive

  14. B. Two cell types • 1. neurons • a. Cell body • b. Axon • c. Dendrite 2. Glia cells (caretakers)

  15. V. Connective Tissues • A. Common traits • 1. possess fibers • 2. widely scattered cells • 3. ground tissue (matrix) • 4. analogy

  16. B. Areolar Connective Tissue-loose irregular

  17. C. Tendon-dense regular

  18. D. Ligament

  19. E. Bone

  20. F. Blood

  21. G. Adipose tissue

  22. VI. Membranes • A. Cutaneous • B. Mucous • 1. contain glands • 2. open to outside • Serous 1. occur in paired sheets 2. don’t open to outside 3. no glandular tissue
