Regarding the blood–brain barrier of the central nervous system
(CNS), which of the following statements is incorrect?
a. It exists due to the specific anatomy and transport
characteristics of the endothelia cells lining the
capillaries of the CNS.
b. Lipid-soluble compounds can cross CNS capillary
walls only through active or passive transport
mechanisms.
c. The endothelial cells of CNS capillaries exhibit very
few pinocytotic vesicles, limiting the movement of
large-molecular-weight compounds into the CNS.
d. None of the above is incorrect.
