ganglion   (gāng'glē-ən)  Pronunciation Key 
Plural ganglia
A compact group of neurons enclosed by connective tissue and having a specific function. In invertebrate animals, pairs of ganglia occur at intervals along the axis of the body, with the forwardmost pair functioning like a brain. In vertebrates, ganglia are usually located outside the brain or spinal cord, where they regulate the functioning of the body's organs and glands as part of the autonomic nervous system.
