OUTLINE

Tuesday Objective 1:  Learn to recognize and distinguish several different types of epithelial tissue.

With your atlas and/or text, familiarize yourself with the epithelial types (i.e., find and identify each epithelial type on one or more of the slides listed below).  

• Stratified squamous epithelium, keratinized
  • skin -- slides 43, 89, 92.
     
• Stratified squamous epithelium, non-keratinized
  • esophagus -- slides 06, 07, 68, 85.
  • cornea -- slide 22.
  • tongue -- slide 46.
  • vagina -- slide 56.
     
• Simple columnar epithelium
  • colon -- slides 09, 38, 48.
  • intestine -- slides 03, 05, 37, 47, 61, 70.
  • stomach -- slides 40, 41, 68.
  • oviduct -- slide 87.
  • uterus -- slide 55.
     
• Cuboidal epithelium (simple and stratified)
  • kidney (renal tubules) -- slide 02.
  • salivary gland (ducts) -- slide 42.
  • tongue (salivary ducts) -- slide 46.
  • skin (sweat glands) -- slides 43, 92.
  • pancreas (ducts) -- 65, 70, 84.
     
• Simple squamous epithelium
  • blood vessels -- slide 30.
  • kidney (Bowman's capsule) -- slide 02.
  • lung alveoli -- slide 51.
     
• Pseudostratifed columnar epithelium
  • trachea -- slides 04, 06, 85.
  • vas deferens -- slide 91.
     
• Transitional epithelium
  • bladder -- slide 08.
  • ureter -- slide 94.
  • kidney (renal pelvis) -- slide 02.

Tuesday Objective 2:  Find both listed types of epithelial tissue on each of the following slides

• Slide 11 -- Eyelid.  Which type of epithelium lies against the eyeball?
• Keratinized stratified squamous epithelium
• Non-keratinized stratified squamous epithelium
   
• Slide 12 -- Soft Palate.  Which type of epithelium is on the roof of the mouth?  Which faces the nasal cavity?
• Non-keratinized stratified squamous epithelium
• Pseudostratified columnar epithelium
   
• Slide 35 -- Recto-anal junction.  Which type of epithelium belongs to the anal canal?  Which belongs to the rectum?
  • Non-keratinized stratified squamous epithelium
  • Simple columnar epithelium
     
• Slide 68 -- Esophago-gastric junction.  Which type of epithelium belongs to the esophagus?  Which belongs to the stomach?
  • Non-keratinized stratified squamous epithelium
  • Simple columnar epithelium

Thursday Objective 1:  Continue Tuesday's epithelial observations.

Objective 2:  Learn to recognize and distinguish glandular epithelial tissue.

Find examples of glandular tissue.  Where possible, distinguish secretory cells from ducts (not all glands have differentiated ducts). 
Use your atlas to identify the glandular tissue in one or more of the examples/slides listed for each of these exocrine glands.

• Sweat glands -- slides 43, 92.
   
• Salivary glands -- slides 12, 42, 46.
   
• Duodenum -- slides 03, 05, 47, 70.
   
• Pancreas -- 65, 70, 84.
   
• Gastric glands -- slides 40, 41, 50.
   
• Uterus -- slide 55.
   
• Mammary gland -- slides 72, 73.
   
• Prostate -- slide 99.
