Editing Autonomic nervous system (section)

=== '''Collateral     ganglia''' ===

** Midgut:
*** '''Coeliac       plexus'''
**** Wholly visceral - supplies        all abdominal organs including gonads
**** Lies around the origin of        coeliac trunk just above the pancreas
**** Contributing fibres
***** Greater and lesser         splanchnic nerves
***** Vagus
**** Mostly connects with        viscera via branches along the aortic vascular supply
*** '''Renal       ganglion''' -       relay for the least splanchnic nerve behind the renal artery
*** There are other       ganglia/plexuses along aorta from SMA to IMA, which I think are quite       variable and are just referred to as 'aorticorenal plexuses' in quite a       general way
** Hindgut: lumbar part of      sympathetic trunk
*** '''Superior       hypogastric plexus'''
**** A fenestrated network of        sympathetic fibres found just below the aortic bifurcation (L5)
**** Caudally fibres exit as        the hypogastric nerves, connecting to the inferior hypogastric        ('pelvic') plexus
*** '''Inferior       hypogastric plexus'''
**** SNS inflow from S3 and S4,        and sometimes S2
**** PNS inflow from S2-S4        (nervi erigentes)
**** Lies between parietal and        visceral layers of endopelvic fascia, lateral to lower third of rectum
**** Preservation is very        important during mobilisation of lateral ligaments of rectum - leads to        genitourinary dysfunction if damaged
