The parasympathetic nervous system is referred to as the " craniosacral outflow "; the pelvic splanchnic nerves are the " sacral " component.

They are found in the same region as the pelvic splanchnic nerves, which arise from the sacral spinal nerves to provide parasympathetic fibers to the inferior hypogastric plexus.

In the distal 1 / 3 of the transverse colon, and through the sigmoid and rectum, and the cervix in females, the pelvic splanchnic nerves supply parasympathetic function, including transmitting the sensation of pain.

The greater splanchnic nerve leaves the vertebral levels T5-T9 and synapses in the abdomen in the celiac ganglia, which innervates the celiac artery The lumbar splanchnic nerves from the upper two lumbar segments synapse in the abdomen on the inferior mesenteric ganglia, associated with the inferior mesenteric artery.

As far as I can tell, the Prostatic Plexus and the Pelvic Splanchnic Nerves relay the "'sensory "'function as well as increased heartbeat, blood pressure, body temperature, etc . and the Pundendal Nerve relays the "'motor "'function ( enabling ejaculation ).
17.
Here four options are available to the fibres : ( 1 ) they can run up the chain and synapse, ( 2 ) they can synapse at the level of entry, ( 3 ) they can pass straight through and synapse elsewhere-such as in the case of T5-12 ( the splanchnic nerves ), or ( 4 ) they can enter the chain and descend to synapse.
