Which neurotransmitter is released into the heart by the vagus nerves that slow the heart?
The parasympathetic division of the autonomic innervation of the heart releases acetylcholine from its varicosities (the sites where neurotransmitter is released). The acetylcholine binds to M-2 muscarinc receptors to mediate the negative chronotropic (slowing of heart rate) effect. This also mediates a negative inotropic (lowering of force of contraction) effect.
Who do varicose veins mostly occur in?
Varicose veins most often occur in people who must sit or stand a lot. More women than men get varicose veins, and more women during or after child-bearing ages develop varicosities. They mostly occur in the lower legs, from the knee down to the ankle, but mostly around the knee and upper calf.
Why are the viens close to the leg surface more vulnerable to varicose veins?
Varicose veins are caused by a defect in the valves directing one way flow inside the veins. When the valves are not functioning correctly, the blood backs up into the surface (superficial) veins and presents as varicosities. The reason that it is more likely to occur in the legs is that there is a greater fluid pressure caused by gravity's effect on the column of blood within your body.
Are varicose veins treatable?
Varicose veins can develop in the deep veins also. Varicose veins in the superficial veins are called primary varicosities, while varicose veins in the deep veins are called secondary varicosities.
