TISSUE REVIEW

  • The following slides are from your text or other sources. This will allow you to study tissues at home.
  • You are also responsible for tissue slides that we view with the microscope in class.
  • Also study the tissue slides and pictures found in the PAL CD or at www.masteringaandp.com
  • know:
    • name of the tissue
    • cells and other structures
    • the function of the tissue
    • where it is found

procedure to identify epithelial tissues

  • Does the tissue contact an opening?
  • Is it made entirely of cells?
  • if it’s epithelial :

    • layers

    • what is the shape of cells
    • other structures - cilia, microvilli, basement membrane
    • what function matches this structure?
  • if it’s not epithelial :
    • see connective tissue procedure
    • muscle, nerve

connective tissue

simple squamous epithelium one layer of flat cells - note the very flat the nuclei

simple squamous epithelium

thin, flat cell ; only one layer

opening = lumen

connective tissue

simple squamous

you’re looking at a thin ring of simple squamous cells that make up the wall of an alveolus in the lung.

You see many, flat nuclei

lung alveoli : simple squamous

Simple cuboidal epithelium (kidney tubules)

Simple cuboidal epithelium Lumen of kidney tubule

Cuboidal cell

Nucleus

this is a longitudinal cut through the tubule

Stratified cuboidal epithelium gland

(gland ducts)

Stratified cuboidal epithelium

Basal cell

Apical cell

Nuclei

Lumen of duct

many circular arrangements of simple cuboidal cells around an opening –

think : gland or kidney

simple cuboidal epithelium

basement membrane

connective tissue

kidney tubules simple cuboidal epithelium

pseudostratified columnar ciliated epithelium ( trachea)

cilia

goblet cell

connective tissue

note: if it’s pseudostratified – those are not microvilli

Pseudostratified epithelium

(trachea)

Cilia

Nuclei of epithelial cells

Pseudostratified epithelium

microvilli

goblet cell

nuclei

What type of tissue is this? Where is it found?

Simple columnar epithelium

(small intestine)

Nucleus of columnar cell

Simple columnar epithelium

Columnar cell

areolar c.t. microvilli^ Goblet cell
