Question

The basement membrane is made up of

• A. Epidermal cell only
• B. Endodermal cell
• C. No cell product of epithelial cell
• D. Both (a) and (b)

Answer 1

Answer: (C)

No cell product of epithelial cell

• Epithelial tissues are sheets of cells adhering to their side, or lateral surfaces.
• They synthesize and deposit at their bottom, or basal surfaces an organized complex of matrix materials known as the basal lamina or basement membrane.
  
• This thin layer serves as a boundary with connective tissue and as a substrate to which epithelial cells are attached.
• The framework of collagen fibrils builds up this membrane along with mucopolysaccharides and glycoproteins.
  

So the correct option is C.
