May inform cutaneous vasoregulation assessment in orthostasis; leaves open relevance to systemic hemodynamic stability.
What are the mechanisms mediating reflex cutaneous vasoconstriction during upright posture in human subjects?
Veno-arteriolar reflexes play a primary role in triggering vasoconstriction in the cutaneous circulation during upright posture in humans.
Vissing et al. (1997) studied this question.
