I was surprised to learn that lymph vessels are innervated by smooth muscle as well as indirect result of the skeletal muscle.
I was wondering if the same is the case for veins. I know that blood in veins moves up against gravity as the skeletal muscle squeezes on the veins and because valves restrict bloodflow, blood is forced upwards. However, is there any smooth muscle innervation to cause blood to move up?
Thanks for the help!
