An axosomatic connection refers to:
Axon to dendrites
Axon to terminal button
Axon to axon
Axon to soma
Once the AP reaches the axon terminal, what channels will open?
VGC for Na+
VGC for Ca+
Leak channels for K+
Leak channels for Na+
What is the meaning of indirect action?
Binding through VCG’s and changing the potential
Acting through 2nd messengers
