title: Growth of sympathetic nerve terminals in the adult rat.
abstract: This report presents evidence that in adult life, in the absence of any experimentally-induced stimulus, the density of sympathetic nerve terminals increases in rat submaxillary salivary glands, suggesting that sympathetic nerve terminal growth continues in adult life. Several theories which have been proposed to account for nerve terminal growth in adult animals are discussed in light of experimental results.
