This suggests that peripheral vasoconstriction-induced by the adrenergic effects of nicotine-may contribute to the observed decline in subcutaneous wound-tissue oxygen. (rnspeak.com)
The peripheral vasoconstriction due to smoking could be inhibited by a selective alpha-1 adrenoceptor blocker. (rnspeak.com)
It results from vasoconstriction and diminished peripheral blood flow, such as occurs in cold exposure, shock, congestive failure, and peripheral vascular disease. (medenosrce.net)
Thus, the sympathetic nervous system counteracts the ensuing pressure drop, and a massive peripheral vasoconstriction commences redistributing circulating blood by reducing blood flow in cutaneous, muscular, and splanchnic circulations, but a maintained or augmented flow to the central nervous system and heart.

Vasodilatation2
This investigation suggests that reflex cold-induced cutaneous vasoconstriction acts independently of NO suppression, whereas hypoxia-induced cutaneous vasodilatation is dependent on NOS-derived NO production. (uea.ac.uk)
The increase in understanding activity brings about vasoconstriction in the visceral organs, whereas the vasodilatation predominates in the blood vessels of the muscles and also the coronary flow because of the regional vasodilatory metabolites. (lightningmetal.shop)

Hypoxic1
Hypoxic modulation of nitric oxide (NO) production pathways in the cutaneous microvasculature and its interaction with cold-induced reflexvasoconstriction, independent of local cooling, have yet to be identified. (uea.ac.uk)
Contributes1
Local thermal control of cutaneous blood vessels also contributes importantly-local warming of the skin can cause maximal vasodilation in healthy humans and includes roles for both local sensory nerves and nitric oxide. (stackexchange.com)
Thermal3
Paraspinal cutaneous thermal asymmetries and anomalies are shown to be suggestive of various pathophysiological alterations, and in particular, the vertebral subluxation complex (VSC). (wholisticthermography.com)
Paraspinal cutaneous thermal anomalies have long been held to be suggestive of vertebral subluxation. (wholisticthermography.com)
For the past several years, we revisited and explored older haenyeos in terms of environmental physiology, beginning with questionnaire and field studies and later advancing to thermal tolerance tests in conjunction with cutaneous thermal threshold tests in a climate chamber. (biomedcentral.com)

Unlike CGRP U-II-induced cutaneous vasodilation is apparently limited by the hearing pinna as U-II didn't induce observable flushing in mucous membranes (e.g. conjunctiva and dental mucosa) aswell as in several other cutaneous tissue including the epidermis from the nares the scrotum or tail (the last mentioned evaluated by cutaneous heat range measurement). (scienceexhibitions.org)
Vessels3
If the air around your skin is comparatively warmer, cutaneous blood vessels will dilate to accommodate a higher flowrate, allowing more blood to engage in heat transfer. (stackexchange.com)
Blood vessels near the surface of the body constrict, a process known as cutaneous vasoconstriction . (adrianagency.com)
The increase in the quantity of reduced hemoglobin in the cutaneous vessels which produces cyanosis may be brought about either by an increase in the quantity of venous blood in the skin as the result of dilatation of the venules and venous ends of the capillaries or by a reduction in the oxygen saturation in the capillary blood. (medenosrce.net)
