The parotid gland of the rat seems to receive some adrenergic nerves from the sympathetic chain of the opposite side. This is suggested by the following evidence: after unilateral removal of the superior cervical ganglion, parotid tissue from the contralateral gland shows degeneration secretion of amylase in vitro similar to, but much smaller than that known to occur ipsilaterally. When parotid secretion is evoked parasympathetically in the anesthetized rat, superimposed stimulation of the contralateral cervical sympathetic trunk can be shown to increase the secretion of amylase into this parasympathetic saliva; as it does, much more, ipsilaterally. It may also cause an evanescent decrease of the salivary flow, suggesting that not only secretory, but also vasoconstrictor nerves had been activated. After removal of one sympathetic ganglion, some undergenerated adrenergic nerves remain ipsilaterally, as earlier demonstrated; but no such fibers can be detected when the ganglion has been removed on both sides.
大鼠的腮腺似乎从对侧的交感神经链接收一些肾上腺素能神经。以下证据表明了这一点：在单侧切除颈上神经节后，来自对侧腺体的腮腺组织在体外显示出淀粉酶分泌退化，类似于同侧已知发生的情况，但程度要小得多。当在麻醉的大鼠中通过副交感神经诱发腮腺分泌时，可以证明对侧颈交感干的叠加刺激会增加淀粉酶向这种副交感神经唾液中的分泌；与同侧相比，增加的幅度要小得多。它还可能导致唾液流量短暂减少，这表明不仅分泌神经，而且血管收缩神经也被激活了。如先前所示，在切除一个交感神经节后，同侧仍保留一些未完全退化的肾上腺素能神经；但当两侧的神经节都被切除时，则检测不到此类纤维。
