Sympathetic
Definition:
(a.) Inclined to sympathy; sympathizing.
(a.) Produced by, or expressive of, sympathy.
(a.) Produced by sympathy; -- applied particularly to symptoms or affections. See Sympathy.
(a.) Of or relating to the sympathetic nervous system or some of its branches; produced by stimulation on the sympathetic nervious system or some part of it; as, the sympathetic saliva, a modified form of saliva, produced from some of the salivary glands by stimulation of a sympathetic nerve fiber.
Example Sentences:

(2) Plasma NPY correlated better with plasma norepinephrine than with epinephrine, indicating its origin from sympathetic nerve terminals.
(3) They are best explained by interactions between central sympathetic activity, brainstem control of respiration and vasomotor activity, reflexes arising from around and within the respiratory tract, and the matching of ventilation to perfusion in the lungs.
(4) Noradrenaline (NA) was released from sympathetic nerve endings in the tissue by electrical stimulation of the mesenteric nerves or by the indirect sympathomimetic agent tyramine.
(5) Following injections of HRP into the apex of the heart, the sinoatrial (SA) nodal region and the ventral wall of the right ventricle, we observed that HRP-labeled sympathetic neurons were localized predominantly in the right stellate ganglia, and to a lesser extent, in the right superior and middle cervical ganglia, and left stellate ganglia.
