Things You Wanted to Know but Were Afraid to Ask About Splanchnic Innervation

What you were afraid to ask about splanchnic innervation:

- How is splanchnic innervation structured?

- How is the solar plexus structured ?

- How are the hypogastric plexuses structured?

To answer the questions How is splanchnic innervation structured?

· Abdominopelvic structures are innervated by the autonomic nervous system. 

· Sympathetic and parasympathetic components from different branches form a nervous network, originating 3 different plexus:

· Celiac [solar] plexus 

· Superior hypogastric plexus

· Inferior hypogastric[pelvic] plexus

· This maintains the normal function of the different organs, regulating their activity.

How is the solar plexus structured?

· The solar plexus is structured into: ganglia, afferences and efferences.

· The various branches merge their fibers, yielding as many branches as the abdominal aorta has.

· It innervates almost all the abdominal viscera

How are the hypogastric plexuses structured?

· There are 2 hypogastric plexuses: superior and inferior

· The superior hypogastric nerve carries autonomic fiber towards the inferior hypogastric plexus.

· The inferior hypogastric plexus has many visceral functions.
