Astrocytes are star shaped glial cells which are found associated
with the neurons of the CNS and spinal cord.
They
modulate the aspects related to neural network functions.
Express
the same sets of ion channels as neurons, but in varying proportion.
Maintenance
of K+ and water homeostasis in the CNS via coordinated action of Kirl.4 and aquaporin 4 channels.
Gap
junctions form intercellular networks and help in sequestering K+ and glutamate.
Modulation
of synaptic transmission.
1. Lamellar
fibrous astrocytes
Found in white matter
Oriented parallel to the neuronal axons
Higher levels of GFAP
End feet envelops the...
