 Which of these statements about the basement membrane is not true?
a.   It is a membrane of phospholipid molecules
b.   It is made of extracellular matric
c.   It separates epithelial cells from the rest of the body
d.   It is also called the basal lamina
e.   All of the above are true 

Answer

• a.   It is a membrane of phospholipid molecules
  Explanation:
  Basement membrane is a thin, fibrous, extracellular matrix which separates the lining of external and internal body surface. Basement membrane separates epithelial cells from rest of the body. Basal lamina is also known as basement membrane and is around 50-100 nm thick. The incorrect statement is option 1, basement membrane does not separate two sides as plasma membrane does, so it does not have phospholipid molecules that forms bilayer in cell membranes.
