Splanchnic

Splanchnic is usually used to describe organs in the abdominal cavity.^[1]

It is used when describing:

• Splanchnic tissue
• Splanchnic organs - including the stomach, small intestine, large intestine, pancreas, spleen, liver,^[2] and may also include the kidney.^[3]
• Splanchnic nerves
• Splanchnic mesoderm
• Splanchnic circulation – the circulation of the gastrointestinal tract originating at the celiac trunk, the superior mesenteric artery and the inferior mesenteric artery.^[4][5]

History and etymology

The term derives from Ancient Greek: σπλαγχνικός, romanized: splanchnikos, meaning "inward parts,^[6][7] organs".^[8]

The term "splanchnologia" is used for grouping in Nomina Anatomica,^[9] but not in Terminologia Anatomica. It includes most of the structures usually considered "internal organs", but not all (for example, the heart is excluded).^[9]
