Identifies cholinergic vasodilation at intramuscular arteries in animals; leaves open relevance to human exercise hyperemia or therapeutics.
Sympathetic cholinergic vasodilation occurs specifically at intramuscular small arteries (50-500 microm), which subsequently increases flow velocity and volume flow in upstream blood vessels.
Matsukawa et al. (2002) studied this question.
