Question

multiple choice 2 points

what are the plexus within the autonomic nervous system typically named for?
scientist who first identified them
directional position of closest major artery
closest major organ
underlying artery

Explanation:

Identify the naming convention of autonomic plexuses

Using the Autonomic Nervous System knowledge point

Autonomic nerve plexuses are networks of sympathetic and parasympathetic fibers located in the thorax, abdomen, and pelvis. These plexuses typically travel along major blood vessels to reach their target organs and are named after the underlying artery they wrap around or follow (for example, the celiac plexus, superior mesenteric plexus, and renal plexus are named after the celiac trunk, superior mesenteric artery, and renal artery, respectively).

Evaluate the given options

• scientist who first identified them: Incorrect, as they are named anatomically rather than eponymously.
• directional position of closest major artery: Incorrect, they are named directly for the artery itself, not its relative directional position.
• closest major organ: Incorrect, while some general regions correspond to organs, the specific plexuses are named for the blood vessels they surround.
• underlying artery: Correct, autonomic plexuses are named after the underlying artery they associate with and travel along.

Answer:

• scientist who first identified them
• directional position of closest major artery
• closest major organ
• underlying artery (Correct answer)
