Octopuses have hundreds of suckers, each one equipped with its own ganglion with thousands of neurons. These 'mini-brains' are interconnected, making for a widely distributed nervous system. That is why a severed octopus arm may crawl on its own and even pick up food.

Dutch Scientist

Used in medical discussions to describe nerve cell clusters in body parts other than the brain and spinal cord.

Medical Context

Appears in technical or professional medical settings, like reports or during surgery.

Technical Usage

Often found with words like 'cyst', 'cell', and 'block' to describe related medical conditions or treatments.

Associated Words

Refers broadly to nerve tissues, often found in biology textbooks or scientific studies.

Biological Term

Typical in academic discussions of neurology and the human nervous system.

Academic Word

Ganglions function like signal relays, prioritizing information sent to the brain.

Understanding Signals

 And why is the physiology different? Well it turns out it's these neuromodulators, just like the neuromodulators in that little tiny ganglion in the crabs. So here's a picture of the octopamine system. Octopamine is a neuromodulator that seems to play an important role in flight and other behaviors.
