  2. Accelerans nerve - Wikipedia

    en.wikipedia.org/wiki/Accelerans_nerve

    Accelerans nerve forms a part of the sympathetic branch of the autonomic nervous system, and its function is to release noradrenaline at its endings on the heart. The heart beats according to a rhythm set up by the sinus-atrial node or pacemaker, which is located on the right atrium of the heart.

  3. Autonomic nervous system - Wikipedia

    en.wikipedia.org/wiki/Autonomic_nervous_system

    Autonomic nervous system, showing splanchnic nerves in middle, and the vagus nerve as "X" in blue. The heart and organs below in list to right are regarded as viscera. The autonomic nervous system has been classically divided into the sympathetic nervous system and parasympathetic nervous system only (i.e., exclusively motor).

  4. Sympathetic nervous system - Wikipedia

    en.wikipedia.org/wiki/Sympathetic_nervous_system

    The afferent fibers of the autonomic nervous system, which transmit sensory information from the internal organs of the body back to the central nervous system (or CNS), are not divided into parasympathetic and sympathetic fibers as the efferent fibers are. [17] Instead, autonomic sensory information is conducted by general visceral afferent ...

  5. Parasympathetic nervous system - Wikipedia

    en.wikipedia.org/wiki/Parasympathetic_nervous_system

    The autonomic nervous system is responsible for regulating the body's unconscious actions. The parasympathetic system is responsible for stimulation of "rest-and-digest" or "feed-and-breed" [ 3 ] activities that occur when the body is at rest, especially after eating, including sexual arousal , salivation , lacrimation (tears), urination ...

  6. Nervous system - Wikipedia

    en.wikipedia.org/wiki/Nervous_system

    The visceral part, also known as the autonomic nervous system, contains neurons that innervate the internal organs, blood vessels, and glands. The autonomic nervous system itself consists of two parts: the sympathetic nervous system and the parasympathetic nervous system. Some authors also include sensory neurons whose cell bodies lie in the ...

  7. Vagus nerve - Wikipedia

    en.wikipedia.org/wiki/Vagus_nerve

    The vagus is the longest nerve of the autonomic nervous system in the human body and comprises both sensory and motor fibers. The sensory fibers have their nuclei either in the jugular or the nodose ganglion, whereas the motor fibers come from neurons of the dorsal motor nucleus of the vagus and the nucleus ambiguus. [2]

  9. Splanchnic nerves - Wikipedia

    en.wikipedia.org/wiki/Splanchnic_nerves

    The splanchnic nerves are paired visceral nerves (nerves that contribute to the innervation of the internal organs), carrying fibers of the autonomic nervous system (visceral efferent fibers) as well as sensory fibers from the organs (visceral afferent fibers).
