Stimulation, Erection, Emission and Ejaculation

The video tutorial explains the innervation of the male reproductive system, focusing on the roles of sympathetic, parasympathetic, and somatic nerves in processes like stimulation, erection, emission, and ejaculation. It details how the pudendal nerve, pelvic splanchnic nerves, and lumbar splanchnic nerves contribute to these functions, highlighting the physiological mechanisms involved, such as nitric oxide-induced vasodilation and norepinephrine-induced contractions.

What is the significance of the pelvic splanchnic nerves in male reproductive physiology?

Describe the pathway of sympathetic nerves during ejaculation.

What mechanisms prevent the mixing of urine and semen during ejaculation?

How do the skeletal muscles contribute to the process of ejaculation?
