Presentation Transcript

  1. Tissue slide

  2. Epithelial tissue Cell shape Arrangement of cell layers. Apical surface – epithelial surface to space / lumen Basal surface – epithelial surface adjacent to basement membrane

  3. Simple Squamous • www.stegen.k12.mo.us/tchrpges/sghs/ksulkowski...air sacs of lungs (alveoli) – diffusion of oxygen and carbon dioxide. Endothelium of capillaries – diffusion between blood and interstitial fluid (tissue fluid). Pg 48 in Lab book.

  4. Simple Cuboidal • www.stegen.k12.mo.us/tchrpges/sghs/ksulkowski... Walls of kidney tubules – absorption from filtration and secretion of other substances into the filtrate. Glands – Secretion of production made by the simple cuboidal cells. Pg 49 in lab book.

  5. Nonciliated simple columnar • www.stegen.k12.mo.us/tchrpges/sghs/ksulkowski...Lining of stomach and intestines – secretion of digestive juices, absorption with microvilli. Pg 50 in book.

  6. Ciliated Simple columnar • www.stegen.k12.mo.us/tchrpges/sghs/ksulkowski...Uterine tubes (Fallopian tubes) cilia that move the ootid to the uterus. Pg 50 in lab book.

  7. Stratified Squamous • www.stegen.k12.mo.us/tchrpges/sghs/ksulkowski...Surface of skin - protective barrier. Mouth and esophagus – protective barrier in area subject to abrasion and friction. Pg. 51 in lab book.

  8. Transitional • www.kumc.edu/.../urinary/small/Ren19s.JPGwww.bu.edu/histology/i/16603hoa.jpg • Lines urinary bladder and part of the ureters and the urethra – protective barrier that permits distension.Pg. 52 in lab book.

  9. Pseudostratified columnar • medinfo.ufl.edu/year1/histo/images/a25c.jpg Lines nasal cavity, trachea, and bronchi – secretion of mucus by goblet cell, cilia which move the mucus toward the pharynx. Pg. 53 in lab book.

  10. Stratified cuboidal • www.stegen.k12.mo.us/tchrpges/sghs/ksulkowski...ducts of adult sweat glands and esophageal – protection and limited secretion and absorption

  11. Stratified columnar • www.cytochemistry.net/.../epithelia/stratified_columnar.htmStratified Columnar epithelium is rare.  One place you can find it is in the largest ducts of salivary glands (parotid, submandibular, etc).  The basal layer of cells are cuboidal cells and the layer nearest the apical surface includes columnar cells.  The large droplets are mucus, in Goblet cells.

  12. Endocrine Glands • www.med-ed.virginia.edu/.../Endocrine4.jpgThe structural unit of the thyroid gland is the follicle that is formed by a sphere of cuboidal epithelial cells.  These hormone-producing cells surround a lumen that is filled with colloid, and each follicle is enmeshed in a capillary network.

  13. Exocrine glands • www.med-ed.virginia.edu/.../Endocrine4.jpgSweat gland - secrete material to the outside via a duct.
