Apical Basal MM Fig. 4-1 p. 70 Lateral Functions of Epithelia • Boundaries • Sealing • Protection • Absorption • Excretion • Transport • Secretion • Sensory reception • Simple – one layer of cells • Stratified – many layers of cells • Pseudostratified – only one layer, but it looks stratified; found in respiratory system Classification First part of name = # cellular layers MM Fig. 4-2 p. 71 Second part of name = Cell shape • Squamous – flat, scaly, or fried egg-like • Cuboidal – square-ish shaped • Columnar – column • Transitional – special, found only in urinary system; lots of cell shapes Hint: Look at nucleus to help determine which kind MM Fig. 4-2 p. 71 Additional Classification:...
