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.

• The vagus has an inhibitory effect on the contraction of the laryngeal muscles.

• The physiological connection between distress and high-pitched crying is mediated by the vagus, in particular the branch of the vagus linking the nucleus ambiguus to the larynx.

• Acoustic analyses of the infant cry emphasize measures of the fundamental frequency, in part because cry production models emphasize the role of the vagus and its relationship to fundamental frequency.

• This method utilizes an electrode implanted near the medulla in order to send electrical impulses to the vagus nerve.

• Activation of the anterior cingulate cortex and vagus nerve is similarly implicated in the experience of heartbreak whether due to social rejection or bereavement.

• However, the very existence of this cranial component has been recently questioned and seen as contributing exclusively to the vagus nerve.

• The pharynx is innervated by the pharyngeal plexus of vagus nerve.
