Class Topics
Title Anat Phys 8/30/06
Objectives

• To assess knowledge of preliminary information
  and begin learning about histology

• Chapter 1 Test
• Histology
• Epithelial tissue
• Keep on beginning and failing. Each time you
  fail, start all over again, and you will grow
  stronger until you have accomplished a purpose -
  not the one you began with perhaps, but one
  youll be glad to remember

5
Simple Squamous

• Flattened cells
• all cells have a free surfaces and are attached
  to basement membrane
• Usually lining blood vessels, air sacs of lungs

6
Stratified Squamous

• Multiple layers of cells
• Resist wear and tear
• Categorized by shape of surface cells
• Top layer are flat (Squamous)
• Esophagus, oral cavity
• Outer layer of skin
• Keratinized

9
Simple Cuboidal

• Single layer of cube-shaped cells
• Many times will have cilia or microvilli
• Found in tubes or ducts
• kidneys, liver, and many glands

10
(No Transcript)
11
Simple Columnar

• Elongated cylindrical cells
• nucleus near the bottom (basement membrane)
• Found in wall of uterus, small intestine
• may contain microvilli

12
(No Transcript)
13
Pseudostratified Columnar

• Looks layered, really not
• all cells anchored to basement membrane
• Cell shape not uniform
• nucleus placement not uniform
• If cilia are present
• Pseudostratified ciliated columnar epithelium
• Found in respiratory tract

15
Glandular Epithelium

• Secretion of a product
• goblet cells
• found in PSCC and columnar epithelium
• secrete mucus
• Glands
• endocrine - inside the body
• exocrine - outside the body

16
Connective Tissue

• Keeps other tissues in place
• Protein fibers found in C.T.
• 1. Collagen
• thick - resists stretching (tensile strength)
• Tendons and ligaments, scar tissue
• 10 of humans weight

17
Connective Tissue

• 2. Elastin
• Elasticity and Extensibility
• can stretch and return to original shape
• skin
• 3. Reticulin
• very thin
• not prominent

18
Connective Tissue

• Fig. 4-2 p. 91
• Many types of connective tissue
