Chapters 3 & 4: Tissues & Integumentary system
Four basic tissue types epithelial connective muscular nervous
Epithelial tissue characteristics
Epithelial tissue characteristics
Glandular epithelia glands composed of one or more cells
Exocrine glands goblet cell
Endocrine glands
How to classify epithelial tissues # of cell layers simple stratified
How to classify epithelial tissues shape of cell shape of nucleus generally reflects cell shape
How to classify epithelial tissues put # of cell layers & shape together to identify type study p. 81 of your text
Epithelial cell attachments basement membrane
Connective tissue characteristics most abundant tissue in body
Connective tissue composed of. . . extracellular matrix and cells
Ground substance
Protein fibers Collagen fibers Elastic fibers Reticular fibers
Cells of connective tissue fibroblasts
Types of connective tissues Fibrous connective tissue loose dense elastic reticular Special connective tissue cartilage bone tissue blood adipose classification based on composition of matrix and types of cells structure & function! see p. 83, Table 4.1

Nervous tissue: made of 2 types of cells neurons glial cells
Integumentary System: our skin!
Functions of skin
Layers of skin epidermis dermis the skin and. . . hypodermis
epidermis dermis hypodermis
Epidermis 2 main cell types keratinocytes; most numerous melanocytes
Dermis Composed of connective tissue
Appendages of skin
