Autonomic ganglia ( GA ; Langley, 1900 ) : A topographic division of vertebrate peripheral ganglia with gray matter regions that are distinguished from the craniospinal ganglia, and for description are divided into paravertebral ganglia, prevertebral ganglia (Gaskell, 1886), and terminal ganglia (Gaskell, 1886). Galen (c173-c192) described at least three pairs; see translations by Duckworth (1962, pp. 217-218), May (1968, pp. 695-696), Smith (1971, p. 179). The term was introduced by Langley (1900, pp. 677-678).

Paravertebral ganglia ( GPAS ; Langley, 1900 ) : A topographic division of autonomic ganglia (Langley, 1900) associated with the sympathetic trunk (Winslow, 1733) and branches arising directly from it, including the carotid ganglion (Lobstein, 1831), sympathetic trunk ganglia (Winslow, 1733), and intermediate ganglia. Falloppio (1561; see Johnstone, 1765, p. 177) is credited with discovering them in macrodissected adult humans, for contemporary terminology see Durward (1951, p. 1126).
