title: Facilitation of adrenal sympathetic efferent nerve activity induced by mechanical stimulation of teeth in the rat.
abstract: The effects of afferent signals from the periodontal mechanoreceptors and muscle spindles of jaw-closing muscles on adrenal nerve activity were examined using anesthetized rats. The adrenal nerve activity increased with pressure stimulation of the teeth and by biting a wooden stick. However, after denervation of the periodontal ligament, the facilitation due to the stick-biting was not observed. These results indicate that periodontal afferents facilitate adrenal nerve activity.
