Examples of vagus

• In contrast, the smart vagus, which originates in the nucleus ambiguus, is distinctly mammalian, and mediates cardiac activity when environmental demands require extrareptilian coping.

• The autonomic component is mediated by the myelinated vagus, which reduces fear and promotes calm behavioral states.

• The vagus also regulates the stress response in other organs such as the bronchi, esophagus, pharynx, and heart.

• This neural influence on the heart is proposed to originate from the nucleus ambiguus via myelinated tracts of the vagus (10th cranial nerve).

• The contribution of the vagus nerve in interleukin-1 beta-induced fever is dependent on dose.

• The vagus, the primary parasympathetic pathway to the heart, rapidly regulates cardiac output during environmental challenge.

• The deceleratory parasympathetic component is provided by the vagus, or tenth cranial nerve.

• These actions are opposed by parasympathetic innervation via the vagus nerve.
