Your thoracic spine is the middle section of your spine. It starts at the base of your neck and ends at the bottom of your ribs. It consists of 12 vertebrae. Your thoracic spine is especially rigid and stable, making it the least common area of injury along your spine.

What is the thorax spine?

Your thoracic spine is the middle section of your spine. It starts at the base of your neck and ends at the bottom of your ribs. It consists of 12 vertebrae. Your thoracic spine is especially rigid and stable, making it the least common area of injury along your spine.

What stabilizes the thoracic spine?

The costovertebral joints are important stabilizers of the thoracic spinal motion segments. The rib cage is fixed to the thoracic spine by the costovertebral joints. Thoracic vertebrae are connected to adjacent vertebrae by the bilateral costovertebral joints.

Which spinal nerves affect which parts of the body?

The nerves of the cervical spine go to the upper chest and arms. The nerves in your thoracic spine go to your chest and abdomen. The nerves of the lumbar spine then reach to your legs, bowel, and bladder. These nerves coordinate and control all the body’s organs and parts, and let you control your muscles.

What are the symptoms of thoracic spinal stenosis?

The most common symptoms experienced with thoracic spinal stenosis include:

  • Limited ability to rotate the torso.
  • Difficulty moving side to side.
  • Sharp pain in the back that radiates to the lower back and legs.
  • Ache or discomfort in the legs.
  • Difficulty walking.
  • Bowel or bladder dysfunction.
  • Paralysis – in rare cases.

Where is your thorax located?

The thorax is the region between the abdomen inferiorly and the root of the neck superiorly.

What does T4 and T5 control?

The T1-T4 thoracic sections control primarily chest muscles and organs, such as the heart and lungs. The T5 – T8 vertebrae affect the abdominal muscles, as well as some of the chest.

What is T4 syndrome?

It is thought that the T4 syndrome is a complex autonomic sympathetic dysregulation with its origin in the upper thoracic spine. Patients can have different symptoms in their hands, headache and also thoracic and/or neck pain.

What part of the spine controls legs?

Lumbar region
Lumbar region The lumbar spinal cord is the lower area of the back. Nerve roots coming from the spinal cord in the lumbar spine control the legs. The lumbar region is where the spinal cord ends (the spinal cord is shorter than the spine).

Does nerve damage show on MRI?

An MRI may be able help identify structural lesions that may be pressing against the nerve so the problem can be corrected before permanent nerve damage occurs. Nerve damage can usually be diagnosed based on a neurological examination and can be correlated by MRI scan findings.

Quels sont les différents types d’anatomie du thorax?

Ce chapitre vise à rappeler l’anatomie normale du thorax et sa représentation radiologique, qu’il s’agisse de la radiographie thoracique, de la tomodensitométrie (TDM) ou de l’imagerie par résonance magnétique (IRM). Chacune des parties qui le composent est agrémentée de planches anatomiques.

Qu’est-ce que la radiographie thoracique standard?

La radiographie thoracique standard réalisée, l’exploration du médiastin repose essentiellement sur la TDM. La TDM à acquisition volumique autorise l’imagerie de la totalité du volume thoracique sans discontinuité anatomique, éventuellement avec une excellente opacification vasculaire.

Quelle est la différence entre l’aorte thoracique et la colonne vertébrale?

L’aorte thoracique est solidaire de la colonne vertébrale par ces aa ICP, l’aorte ascendante et l’arc de l’aorte sont solidaires du cœur. Dans les décélérations brutales, peut donc se produire une rupture de l’aorte au niveau de son isthme.

Quels sont les atouts de l’étude de la paroi thoracique?

Les multiples incidences possibles (coronale, sagittale, strictes ou obliques) et la haute résolution en contraste demeurent des atouts fondamentaux dans l’étude de la paroi thoracique, notamment celle de l’apex pulmonaire et du rachis dorsal. Cet apport multiplanaire fournissait des éléments précieux en l’absence du scanner multidétecteurs.
