  2. Sympathetic nervous system - Wikipedia

    en.wikipedia.org/wiki/Sympathetic_nervous_system

    Because its cells begin in the thoracolumbar division – the thoracic and lumbar regions of the spinal cord – the sympathetic nervous system is said to have a thoracolumbar outflow. Axons of these nerves leave the spinal cord through the anterior root. They pass near the spinal (sensory) ganglion, where they enter the anterior rami of the ...

  3. Wide dynamic range neuron - Wikipedia

    en.wikipedia.org/wiki/Wide_dynamic_range_neuron

    Spinal Cord Sectional Anatomy. WDR neurons are found in the posterior grey column of the spinal cord. [3] This area of the spinal cord houses two different types of neurons involved in the process of pain: WDR neurons and nociceptive specific neurons (NS). [4] As the name implies, NS neurons give specific short range responses. [5]

  4. Sympathetic ganglia - Wikipedia

    en.wikipedia.org/wiki/Sympathetic_ganglia

    The sympathetic ganglia, or paravertebral ganglia, are autonomic ganglia of the sympathetic nervous system. Ganglia are 20,000 to 30,000 afferent and efferent nerve cell bodies that run along on either side of the spinal cord. Afferent nerve cell bodies bring information from the body to the brain and spinal cord, while efferent nerve cell ...

  5. Autonomic nervous system - Wikipedia

    en.wikipedia.org/wiki/Autonomic_nervous_system

    The sympathetic ganglia here, are found in two chains: the pre-vertebral and pre-aortic chains. The activity of autonomic ganglionic neurons is modulated by "preganglionic neurons" located in the central nervous system. Preganglionic sympathetic neurons are located in the spinal cord, at the thorax and upper lumbar levels.

  6. Gate control theory - Wikipedia

    en.wikipedia.org/wiki/Gate_control_theory

    The authors proposed that both thin (pain) and large diameter (touch, pressure, vibration) nerve fibers carry information from the site of injury to two destinations in the spinal cord: transmission cells that carry the pain signal up to the brain, and inhibitory interneurons that impede transmission cell activity.

  7. Spinothalamic tract - Wikipedia

    en.wikipedia.org/wiki/Spinothalamic_tract

    This fact aids in determining whether a lesion is in the brain or the spinal cord. With lesions in the brain stem or higher, deficits of pain perception, touch sensation, and proprioception are all contralateral to the lesion. With spinal cord lesions, however, the deficit in pain perception is contralateral to the lesion, whereas the other ...

  8. Sympathetic trunk - Wikipedia

    en.wikipedia.org/wiki/Sympathetic_trunk

    The sympathetic trunk is a fundamental part of the sympathetic nervous system, and part of the autonomic nervous system. It allows nerve fibres to travel to spinal nerves that are superior and inferior to the one in which they originated. Also, a number of nerves, such as most of the splanchnic nerves, arise directly from the trunks.

  9. Spinoreticular tract - Wikipedia

    en.wikipedia.org/wiki/Spinoreticular_tract

    The tract transmits slow nociceptive/pain information (but thermal, and crude touch information as well) from the spinal cord to reticular formation which in turn relays the information to the thalamus via reticulothalamic fibers as well as to other parts of the brain (as opposed to the spinothalamic tract - the direct pathway of the ...
