Test The Arousal Phase

QUESTION 1: What is the central biological mechanism that explains genital responses during arousal?

Lubrication depends only on physical stimulation and never stops
Anxiety or distraction can disrupt lubrication even if there is physical stimulation
Erection is controlled by voluntary volition
Increased diameter of the clitoris reduces blood flow

At the extragenital level the nipples become erect and a sexual flush may appear
Vaginal lubrication is the main extragenital manifestation
The scrotum in women increases in thickness
Parasympathetic response inhibits vasocongestion

Pressure to achieve an erection always enhances it
Erection is an act of conscious will
Pressure to achieve an erection may activate the sympathetic system which inhibits it
Bystander role enhances feedback between brain and genitalia
