Understanding Animal Tissues: Epithelial, Muscle, Nerve, and Connective Tissues
Explore the four general categories of animal tissue - epithelial, muscle, nerve, and connective tissues. Learn about the traits, classification, examples, and functions of each type of tissue. From the tightly packed cells of epithelial tissue to the excitable nature of muscle tissue, delve into the fascinating world of animal tissues.

I. Generalizations A. Definition B. Four general categories of animal tissue 1. epithelial 2. muscle 3. nerve 4. connective
II. Epithelial tissue A. 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
B. Naming or classifying epithelial tissue 1. First Name a. Simple b. Stratified c. Pseudostratified 2. Second name a. Cuboidal b. Squamous c. Columnar
C. Examples of naming 1. simple cuboidal 2. stratified squamous 3. pseudostratified 4. stratified cuboidal
D. Specific examples 1. stratified squamous a. Location b. function
Examples continued 2. transitional a. Location b. Function

V. Connective Tissues A. Common traits 1. possess fibers 2. widely scattered cells 3. ground tissue (matrix) 4. analogy
VI. Membranes A. Cutaneous B. Mucous 1. contain glands 2. open to outside C. Serous 1. occur in paired sheets 2. don t open to outside 3. no glandular tissue
