Video from Dr Matt & Dr Mike on YouTube
Classify adrenoceptors (α₁, α₂, β₁, β₂, β₃) by location, G-protein coupling, second messenger and response.
Why this video
It provides a clear framework to classify alpha and beta adrenoceptor subtypes by their G-protein coupling, cellular signaling mechanisms, anatomical distribution, and physiological responses.
Heads up
Be aware of the course convention regarding dual coupling of β₂-adrenoceptors to both Gs and Gi in cardiac tissue, as basic reviews typically only present canonical Gs coupling.
