Normally, α-adrenergic receptors predominates in smooth muscle of resistance vessels.

As in the present study, increased eNOS levels correlated with de novo expression in the small resistance vessels in the lung [ 14, 18].

In rabbit, Cycloidal Vibrations at 22-62 Hz increases blood flow within 1-2 minutes due to an increased dilation in the resistance vessels of skeletal muscle.

Thus, dilating the resistance vessels in the coronary circulation causes blood to be shunted away from the coronary vessels supplying the ischemic zones, creating more ischemia.

Distributing arteries (or muscular arteries) are medium-sized arteries that draw blood from an elastic artery and branch into "resistance vessels" including small arteries and arterioles.

Conventional methods used to examine intrinsic properties of isolated resistance vessels (arterioles and small arteries with diameters varying between 30 m and 300 m) include the pressure myography technique.

The contractile function of vascular smooth muscle also regulates the lumenal diameter of the small arteries-arterioles called resistance vessels, thereby contributing significantly to setting the level of blood pressure.

Since it is contractile, depending upon the ratio of its length to its radius, it can act either like a contractile chamber propelling the fluid ahead, or as a resistance vessel tending to stop the lymph in its place.

Based on the fact that PGE2 stimulates cAMP generation in freshly isolated preglomerular renal arterioles [ 14 ] , the cAMP-stimulating EP2 or EP4 receptor has been thought to mediate these effects of PGE2 on renal resistance vessels.

Within the autoregulatory range, as CPP falls there is, within seconds, vasodilatation of the cerebral resistance vessels, a fall in cerebrovascular resistance and a rise in cerebral-blood volume (CBV), and therefore CBF will return to baseline value within seconds (see as ref.
