Electrical stimulation of the stellate ganglion is ...
you're right! heart rate is the only option under sympathetic control.
Stellate ganglion --> sympathetics for sweat to skin in UE + head. Apparently also to increase HR (some cardiologists ablate stellate ganglion for tachy that cant be controlled by beta blockers).
The stellate ganglion is a sympathetic ganglion, so it wouldn’t increase vasodilation in the skin of the upper extremity. Also in most people, the inferior cervical ganglion is fused with the first thoracic ganglion (T1), forming the stellate ganglion.
Got this wrong too. I think upper extremity skin vasodilation (which I picked) is probably more due to local metabolites.
