* Erection is characterized by a marked increase in rigidity of the penis.
* Erection is characterized by a marked increase in rigidity of the penis.
* Increased rigidity is the result of increase in arterial inflow of blood compared to venous outflow.
* Increased rigidity is the result of increase in arterial inflow of blood compared to venous outflow.
* Erection requires that blood be trapped within the cavernous sinus of the penis.
* Erection requires that blood be trapped within the cavernous sinus of the penis.
* Increased blood flow to the penis is brought about by vasodilation of the arterioles supplying it.
