1 layer of column shaped cells with nuclei at many levels always contain goblet cells and cilia
Located at nasal cavity lining
For protection and secretion

Question 10

Transitional epithelium

Answer 10

Many layers of cuboidal cells
Called transitional epithelium because cells undergo a transition in shape and become flat as urine bladder fills with urine
