Solution
Penile erection:
It is the result of a complex interaction of psychological, neurological, vascular, and endocrine components, and is frequently related to sexual arousal or sexual attraction, though it can also occur spontaneously.
The penile erection mechanism is –
- Stimulation of sexual organs
- Nitric oxide is released by parasympathetic neurons, causing the tiny arterioles of the penis to dilate
- Blood clots in vascular spaces of penis' erectile tissues
- Swelling of the penis and erect posture.
