The thoracic spinal nerve 6 (T6) is a spinal nerve of the thoracic segment. [ 1 ] It originates from the spinal column from below the thoracic vertebra 6 (T6).
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 ...
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.
Hemivertebrae are wedge-shaped vertebrae and therefore can cause an angle in the spine (such as kyphosis, scoliosis, and lordosis). Among the congenital vertebral anomalies, hemivertebrae are the most likely to cause neurologic problems. [5] The most common location is the midthoracic vertebrae, especially the eighth (T8). [6]
The fourth thoracic vertebra, together with the fifth, is at the same level as the sternal angle. The thoracic spinal nerve 4 (T4) passes inferior it. A thoracic spine X-ray of a 57-year-old male. Surface orientation of T3 and T7, at middle of spine of scapula and at inferior angle of the scapula, respectively.
Middle back pain, also known as thoracic back pain, is back pain that is felt in the region of the thoracic vertebrae, which are between the bottom of the neck and top of the lumbar spine. It has a number of potential causes, ranging from muscle strain to collapse of a vertebra or rare serious diseases.
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]
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 ...
