• HW - 1
• Sketches of specific tissues
• No more than 4 per page
• Single sided
• List major characteristics and where typically
  found
• Due 6/25 beginning of lab prior to exam
• Diminished credit if turned in late

7

• Epithelial p 56 in text
• Common characteristics
• Types
• Keratinized and nonkeratinized stratified
  squamous
• Simple squamous
• Simple columnar
• Simple Cuboidal
• Pseudostratified ciliated columnar

8

• Epithelial Tissue
• Functions protection, absorption, secretion
• Cover all virtually all body surfaces, in and out
• Lack vascular supply
• Classified based on shape and stacking of cells
• Generally supported on a basement membrane (
  connective tissue)

9

• Classification of epithelial tissues
• 1) Cell shape (at free surface)
• a) squamous - flat cells
• b) cuboidal - cube shaped
• c) columnar - column shaped

Reminders -histology thin section of a 3D
object -there are MANY tissues on each slide
10

• Classification of epithelial tissues
• 2) Cell layers/arrangement
• a) simple - a single layer
• - relatively thin/fragile
• - found lining internal structures
• - simple squamous epithelium pictured here
• b) stratified -multiple layers
• -thicker
• -may be in areas w/ stress
• -stratified squamous epithelium w/out
  keratin pictured here

Name this epithelial tissue
13

• Pseudostratified Columnar (Fig 3.6.b)
• -Lining much of the respiratory tract
• -often have cilia goblet cells
• -looks layered BUT there is really only 1 layer
  of cells with nuclei at different heights

• Connective p 64 in text
• Common characteristics
• Types
• Dense
• Cartilage
• Bone
• areolar
• Adipose
• Blood

17

• Connective Tissue
• Most abundant tissue in body
• Not on free surfaces
• Cells separated in a matrix (ground substance
  fibers)
• Good nerve blood supply (except cartilage
  tendons- dense connective)
• Classified based on matrix components,
  arrangement and type of protein fibers
