  2. Spinal nerve - Wikipedia

    en.wikipedia.org/wiki/Spinal_nerve

    Each thoracic nerve T1T12 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 in the head, neck, thorax and abdomen.

  3. Thoracic vertebrae - Wikipedia

    en.wikipedia.org/wiki/Thoracic_vertebrae

    In vertebrates, thoracic vertebrae compose the middle segment of the vertebral column, between the cervical vertebrae and the lumbar vertebrae. [1] In humans, there are twelve thoracic vertebrae of intermediate size between the cervical and lumbar vertebrae; they increase in size going towards the lumbar vertebrae.

  4. Somatic nervous system - Wikipedia

    en.wikipedia.org/wiki/Somatic_nervous_system

    The spinal nerves are arranged into 31 pairs according to the regions of the spinal cord. To be more precise, there are eight pairs of cervical nerves (C1–C8), twelve pairs of thoracic nerves (T1T12), five pairs of lumbar nerves (L1–L5), five pairs of sacral nerves (S1–S5), and one pair of coccygeal nerves. Peripheral nerves are ...

  5. Thoracic spinal nerve 1 - Wikipedia

    en.wikipedia.org/wiki/Thoracic_spinal_nerve_1

    The thoracic spinal nerve 1 (T1) is a spinal nerve of the thoracic segment. [1] It originates from the spinal column from below the thoracic vertebra 1 (T1).

  6. Neuromere - Wikipedia

    en.wikipedia.org/wiki/Neuromere

    It includes spinal cord segments from about C4 to T1. The vertebral levels of the enlargement are roughly the same (C4 to T1). Lumbosacral enlargement - corresponds to the lumbosacral plexus nerves, which innervate the lower limb. It comprises the spinal cord segments from L2 to S3 and is found about the vertebral levels of T9 to T12.

  7. Thoracic spinal nerve 12 - Wikipedia

    en.wikipedia.org/wiki/Thoracic_spinal_nerve_12

    The thoracic spinal nerve 12 (T12) is a spinal nerve of the thoracic segment. [1] It originates from the spinal column from below the thoracic vertebra 12 (T12). It may also be known as the subcostal nerve.

  8. Facet joint - Wikipedia

    en.wikipedia.org/wiki/Facet_joint

    In the thoracic and lumbar spine, the facet joints are innervated by the medial branch nerves from the vertebral segment above the upper segment and the upper segment. For example, the facet joint between T1 and T2 is innervated by C8 and T1 medial branch nerves. Facet joint between L1 and L2; the T12 and L1 medial branch nerves.

  9. Spinal posture - Wikipedia

    en.wikipedia.org/wiki/Spinal_posture

    Looking directly at the front or back of the body, the 33 vertebrae in the spinal column should appear completely vertical. From a side view, the cervical (neck) region of the spine (C1–C7) is bent inward, the thoracic (upper back) region (T1T12) bends outward, and the lumbar (lower back) region (L1–L5) bends inward.
