Histo M3

• 1 layer = simple
• stratified = 2 or more layers
• these are thin, flat cells = squamous
• cell width and thickness are similar = cuboidal
• columnar = cells are taller than wide
• false stratified = pseudostratified
• lines digestive organs, lungs, and heart = mesothelium
• lines lumina of the heart chambers and interior of blood or lymphatic vessels = endothelium
• flat, adhere tightly to each other to form a sheet = surface view
• spindle-shaped cells with prominent oval nuclei = transverse section
• outer portion of bowman’s capsule = simple squamous
• what type of epithelial tissue is present in excretory or secretory ducts of different organs?

  simple cuboidal
• these are small, nonmotile projections that cover or increase the surface area of absorptive cells = microvilli
• what is the brush border of microvilli?

  proximal convoluted tubule
• what type of epithelial tissue is present in digestive organs?

  simple columnar
• finger-like structures which increases the absorptive surface = villi
• what are the 2 cell types of simple columnar?

  columnar cells and goblet cells
• these are pale-staining secretes mucus = goblet cells
• other locations for simple columnar?

  fallopian tubes
• cilia are nonmotile structures?

  false
• this type of epithelium lines the upper respiratory passages?

  pseudostratified columnar ciliated
• stratified squamous can also be found in the lumina of epididymis and vas deferens = false
• what are the two types of stratified squamous?

  keratinized and nonkeratinized
• this type of epithelium can be found in anal canal = stratified squamous nonkeratinized
• cornea has simple columnar nonkeratinized epithelial cells?

  false
• enumerate the layers of epidermis (ascending)

  • stratum lucidum
  • stratum basale
  • stratum spinosum
  • stratum granulosum
  • stratum corneum
• what is the part of epidermis that is only present in thick skins?

  stratum lucidum
• this type of epithelium lines the larger excretory ducts of the pancreas, salivary glands, and sweat glands = stratified cuboidal or columnar
• ovarian follicles has transitional epithelium?

  false
• is stratified columnar located in mammary glands?

  true
• this assume different shapes depending onthe volume of fluid it holds = transitional epithelium
• what type of epithelium that lines the major and minor calyses, pelvis, ureters, and urinary bladder?
