Histology Review Part 1

• ***Serous Demilune***

• Be able to distinguish between mucous unit (lighter) and serous unit (darker)

kidney

• simple squamous epithelium (parietal layer of Bowman’s capsule)

• simple cuboidal epithelium (around the ducts)

skin (thin, not palmar or plantar)

• stratified squamous keratinized (you must say keratinized or it will be wrong) epithelium

• dense irregular connective tissue (dermis)

• this is collagen type 1 (pink)

• stratified cuboidal epithelium (around the sweat duct)
  

• adipose tissue (looks like chicken wire)

• sebaceous gland

  • cells with foamy appearance associated with a hair follicle and not found in thick palmar or plantar skin-no one has hairy palms-hopefully anyway)

esophagus

• stratified squamous non-keratinized epithelium (also found in the vagina) *remember to write non-keratinized or it will be wrong

• loose aerolar connective tissue (underneath the epithelium)

jejunum

• simple columnar epithelium with goblet cells and brush border (you must write out that entire name or it will be wrong)

• Paneth cells (this is another one that he always asks)

• popular secondary question:what does it secrete?-lysozyme*

• plasma cells (black dots in the loose areolar connective tissue)

  • part of the immune system and necessary because of the nasty stuff we eat especially in Dominica!

ileum (you can also use colon)

• myenterric (Auerbach’s) plexus

  • parasympathetic plexus located between the two layers of smooth muscle and is found through the GI tract

stomach

• simple columnar epithelium (also in gallbladder)

  • notice the lighter color staining because each cell is mucous secreting

  • therefore NO goblet cells or brush border
