  2. Thoracic splanchnic nerves - Wikipedia

    en.wikipedia.org/wiki/Thoracic_splanchnic_nerves

    Thoracic splanchnic nerves are splanchnic nerves that arise from the sympathetic trunk in the thorax and travel inferiorly to provide sympathetic supply to the abdomen.

  3. Long thoracic nerve - Wikipedia

    en.wikipedia.org/wiki/Long_thoracic_nerve

    The long thoracic nerve descends through the cervicoaxillary canal. It is posterior to the brachial plexus, [3] and the axillary artery and vein. [4] This takes it deep to the clavicle. [2] It rests on the outer surface of the serratus anterior muscle. It extends along the side of the thorax to the lower border of the serratus anterior muscle ...

  4. Thoracic outlet syndrome - Wikipedia

    en.wikipedia.org/wiki/Thoracic_outlet_syndrome

    Thoracic outlet syndrome (TOS) is a condition in which there is compression of the nerves, arteries, or veins in the superior thoracic aperture, the passageway from the lower neck to the armpit, also known as the thoracic outlet. [1] There are three main types: neurogenic, venous, and arterial. [1]

  5. Thoracic ganglia - Wikipedia

    en.wikipedia.org/wiki/Thoracic_ganglia

    The thoracic ganglia are paravertebral ganglia. The thoracic portion of the sympathetic trunk typically has 12 thoracic ganglia . Emerging from the ganglia are thoracic splanchnic nerves (the cardiopulmonary, the greater, lesser, and least splanchnic nerves) that help provide sympathetic innervation to thoracic and abdominal structures.

  6. Medial pectoral nerve - Wikipedia

    en.wikipedia.org/wiki/Medial_pectoral_nerve

    The medial pectoral nerve (also known as the medial anterior thoracic nerve) is (typically) a branch of the medial cord of the brachial plexus and is derived from spinal nerve roots C8-T1. It provides motor innervation to the pectoralis minor muscle , and the lower half (sternal part) of the pectoralis major muscle .

  7. Posterior branches of thoracic nerves - Wikipedia

    en.wikipedia.org/wiki/Posterior_branches_of...

    The medial cutaneous branches of the posterior divisions of the thoracic nerves descend for some distance close to the spinous processes before reaching the skin, while the lateral branches travel downward for a considerable distance—it may be as much as the breadth of four ribs—before they become superficial; the branch from the twelfth thoracic, for instance, reaches the skin only a ...

  8. Intercostal nerves - Wikipedia

    en.wikipedia.org/wiki/Intercostal_nerves

    The intercostal nerves are part of the somatic nervous system, and arise from the anterior rami of the thoracic spinal nerves from T1 to T11. [1] [2] The intercostal nerves are distributed chiefly to the thoracic pleura and abdominal peritoneum, and differ from the anterior rami of the other spinal nerves in that each pursues an independent course without plexus formation.

  9. Nerve plexus - Wikipedia

    en.wikipedia.org/wiki/Nerve_plexus

    A nerve plexus is composed of afferent and efferent fibers that arise from the merging of the anterior rami of spinal nerves and blood vessels. There are five spinal nerve plexuses, except in the thoracic region, as well as other forms of autonomic plexuses, many of which are a part of the enteric nervous system. The nerves that arise from the ...
