51. Alpha1-receptors in sex organs inhibit ejaculation and in liver cause glycogenolysis.
52. Alpha2-receptors present in the pre-junctional nerve terminals decrease release and synthesis of NE, platelet aggregation and decrease insulin secretion.
53. Beta1-receptors in the heart in SA node increase HR (+ve inotropic effect), AV node increase conduction velocity (+ve dromotropy).
54. Beta2-receptors in the blood vessels cause vasodilation leads to decrease PVR, decrease diastolic pressure, decrease after load, uterus relaxation, and bronchioles dilation.
55. Beta2-receptors in skeletal muscles increase glycogenolysis leads to contractility (tremor), in liver cause glycogenolysis, in pancreas increase insulin secretion.
