1. Ejaculation
Ejaculation is a two-part spinal reflex that involves: * movement of semen into the urethra in response to signals from the internal pudendal nerves (afferent), and hypgastric nerves (efferent), and * propulsion of the semen out of the urethra by contraction of the bulbocavernosus muscle in response to signals from the sacral roots and the internal pudendal nerves.
