norepinephrine uptake
norepinephrine uptake
The directed movement of norepinephrine into a cell, typically presynaptic neurons or glial cells. Norepinephrine (3,4-dihydroxyphenyl-2-aminoethanol) is a hormone secreted by the adrenal medulla and a neurotransmitter in the sympathetic peripheral nervous system and in some tracts of the CNS. It is also the biosynthetic precursor of epinephrine.
