A group of nerve cells forming a nerve center, especially one located outside the brain or spinal cord. Also called neuroganglion.
A benign tumorlike cyst containing mucopolysaccharide-rich fluid enclosed within fibrous tissue and usually attached to a tendon sheath in the hand, wrist, or foot. Also called myxoid cyst, synovial cyst.

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.
