  2. Long thoracic nerve - Wikipedia

    en.wikipedia.org/wiki/Long_thoracic_nerve

    The long thoracic nerve arises from the anterior rami of cervical spinal nerves C5, C6, and C7. [1] [2] [3] The root from C7 may occasionally be absent. [4]The roots from C5 and C6 pierce through the scalenus medius, while the C7 root passes in front of the muscle.

  3. 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 ...

  4. 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.

  5. Spinal nerve - Wikipedia

    en.wikipedia.org/wiki/Spinal_nerve

    The thoracic nerves are the twelve spinal nerves emerging from the thoracic vertebrae. Each thoracic nerve T1–T12 originates from below each corresponding thoracic vertebra . Branches also exit the spine and go directly to the paravertebral ganglia of the autonomic nervous system where they are involved in the functions of organs and glands ...

  6. Medial pectoral nerve - Wikipedia

    en.wikipedia.org/wiki/Medial_pectoral_nerve

    The medial pectoral nerve usually arises from the medial cord of the brachial plexus; it can however occasionally arise directly from the anterior division of the inferior trunk of the brachial plexus. [1] [2] It is derived from the eighth cervical (C8) and first thoracic (T1) spinal nerve roots. [1] The origin is situated posterior to the ...

  7. Lateral pectoral nerve - Wikipedia

    en.wikipedia.org/wiki/Lateral_pectoral_nerve

    The lateral pectoral nerve (also known as the lateral anterior thoracic nerve) arises from the lateral cord of the brachial plexus, [1] [2] and through it from the C5-7. [1] [2] It passes across the axillary artery and vein, [3] pierces the clavipectoral (coracoclavicular) fascia, and enters the deep surface of the pectoralis major to innervate ...

  9. Thoraco-abdominal nerves - Wikipedia

    en.wikipedia.org/wiki/Thoraco-abdominal_nerves

    The anterior divisions of the seventh, eighth, ninth, tenth, and eleventh thoracic intercostal nerves are continued anteriorly from the intercostal spaces into the abdominal wall; hence they are named thoraco-abdominal nerves (or thoracicoabdominal intercostal nerves).
