Term
| Where does the sympathetic chain end? |
|
Definition
| The pelvic portion of each sympathetic trunk is situated in front of the sacrum, medial to the anterior sacral foramina. It consists of four or five small sacral ganglia, connected together by interganglionic cords, and continuous above with the abdominal portion. Below, the two pelvic sympathetic trunks converge, and end on the front of the coccyx in a small ganglion, the ganglion impar (or ganglion of Walther) |

Term
| What are the pelvic splanchnic nerves? What do they do, where do they come from, where do they go? |
|
Definition
| They come from S2-4. They go to the pelvis and synapse in the inferior hypogastric plexuses (on both sides of the pelvis). They provide parasympathetic to everything distal L colic flexure |

Term
| What are sacral splanchnic nerves? |
|
Definition
| These are sympathetic splanchnic nerves. They originate from the sympathetic chain in the sacrum. They go to the inferior hypogastric plexus, where they usually synapse on ganglia. |
