Species differences preclude extrapolating cat/dog cholinergic vasodilation to humans; leaves open primate-specific mechanisms for targeted study.
The study provides histochemical evidence supporting physiological findings that skeletal muscles of monkeys and humans lack sympathetic cholinergic vasodilator innervation, unlike cats and dogs.
Bolme et al. (1970) studied this question.
