• Basement membrane


  made up of protein

  basal lamina: top layer

  reticular lamina: bottom layer
• Epithelial membranes

  1. cutaneous (skin)
  2. mucous (secrete mucus)
  3. serous (secrete serous fluid)
• Non-epithelial membranes

  1. synovial (between joints)
  2. basement
• Epithelial parts

  1. apical/luminal: outside
  2. basal: inside
  3. lateral: sides
• Avascular


  no blood vessels
• Epithelial shapes

  1. squamous (pancake)
  2. cuboidal
  3. columnar
• Epithelial layers

  1. simple: one layer
  2. stratified: multiple layers
  3. pseudo-stratified: looks columnar, one layer
• Endothelium 


  simple squamous lining of blood vessels and the heart
• Mesothelium 


  epithelial component of serous membranes and secrete lubricating fluid
• Stratified squamous epithelia


  keratinized: dead cells

  non-keratinized: alive with nucleus

  para-keratinized: half and half
• Tubular gland

  straight or coiled
• Acinar gland


  flask shaped
• Tubuloacinar


  compound: splitting ducts

  branched: splitting glands
• Merocine secretion


  watery substance, liquids
• Apocrine secretion


  secretion of cell fragments
• Holocrine secretion


  secretion of oils, sebaceous glands
