Answer for 7

Incase of Anxiety erectile dysfunction ,Anxiety creates the stress response in the brain. The amygdala part of brain interprets the fear and send  the distress signal to hypothalamus. The central system hypothalamus functions in integrating the signal from area of brain to the rest of the body part through sympathetic and parasympathetic control system whcih control the heart rate ,blood pressure, vasoconstrction and vasodialtion. The sympathetic nervous system accelerate the "fight and flight" response by providing the body with enormous energy to respons to the fear,anxiety.The parasympathetic control gets shut off for the moment and gets activated once anxiety is over to calm our body system through "rest and digest" response. once sympathetic nervous system is accelerated ,it send signal to the adrenal galnd via autonomic nerves and promotes release of epinephrine into bloodstream .Epinephrine causes heart rate to increase, pushes blood to the muscle, extra oxygen supply to brain promotes attentiveness.It also stimulate the release of blood glucoxe and fat from the temporary storage site of the body.Due to these physiological chnages blood flow to the peniss get reduced significantly and therefore erection function remains dysfunctioned ,causes anxiety erectile dysfunction.
