However, T1 somewhat resembles the last cervical vertebra C7 and T9 — T12 progressively look more like the lumbar vertebrae. The opening is formed by the inferior vertebral notch on the vertebra above and the superior vertebral notch on the vertebra below. The opening, which is also called the neural foramen or lateral foramen , serves as a passageway for a spinal nerve and a pair of nerve roots.
The sacrum and coccyx bones sit inferior to the fifth lumbar vertebra. They are composed of individual vertebra that usually fuse during early adulthood. An intervertebral disk acts as shock absorber between each of the vertebrae in the spinal column by keeping the vertebrae separated when there is…. The vertebral column, also known as the spinal column, is a flexible column that encloses the spinal cord and also supports the head.
It consists of…. The T12 vertebra is the twelfth thoracic vertebra in the spine of the human body. It is part of the spinal column, which supports the top of the human….
The human backbone is a column of 33 total vertebrae, of which 24 are movable and free the remainder are fused. The movable vertebrae are divided…. The vertebral column, or spinal column, is made up of a total of 33 vertebrae, which are subdivided into five regions: cervical, thoracic, lumbar….

T1 - T8 Spinal Cord Injuries The first eight segments of the thoracic spine connect to the rib cage and control the trunk of the body. Author: Spinalcord. What is the T1 Vertebra? What is the T2 Vertebra? What is the T3 Vertebra? What are the T4-T8 Vertebrae?
Where is the T1 Vertebra Located? Where is the T2 Vertebra Located? Where is the T3 Vertebra Located? Where are the T4-T8 Vertebrae Located? T2 Vertebra Pain Symptoms Since the T2 vertebra helps control the heart, T2 vertebra pain symptoms may include chest pain, as well as heart trouble and a disruption in cardiac rhythm.
T3 Vertebra Pain Symptoms The T3 vertebra controls the lungs and bronchial tubes, as well as other chest muscles. Symptoms of a T3 vertebra injury include breathing difficulties, asthma, cough, as well as ailments such as bronchitis, influenza, and pneumonia T4-T8 Vertebrae Pain Symptoms The T4 vertebra has nerves controlling the gallbladder and common duct, though it does affect the lungs and bronchial tubes additionally.
T1-T8 Differences Defined The T1-T8 vertebrae have similarities such as each of these thoracic vertebrae being directly attached to the rib cage and containing nerve roots that exit the spinal column at each vertebral level of the spine.
Each can be referred individually as: T1: First thoracic vertebra T2: Second thoracic vertebra T3: Third thoracic vertebra T4: Fourth thoracic vertebra T5: Fifth thoracic vertebra T6: Sixth thoracic vertebra T7: Seventh thoracic vertebra T8: Eighth thoracic vertebra T1-T8 Spinal Cord Injury Types Injuries to the spinal cord tissue or nerve roots impact physical function according to their vertebral level.
Misalignments Misalignment, also known as subluxation, is when a vertebra is out of alignment. T1-T8 SCI Vertebrae Treatment Treatment for thoracic spinal cord injuries is aimed at strengthening the body as a whole and preserving any remaining function that remains after the injury. Current treatments available for spinal cord patients are: Drugs : Anti-inflammatory drugs are used immediately upon diagnosis of a spinal cord injury.
This is to aid in lessening the inflammation in the affected area and encourage motor and sensory function. Surgery : Patients may need to have decompression surgery to relieve pressure from the spine and surrounding nerves.
Fusion may also be done in order to stabilize the damaged area to ensure further damage does not occur. Therapy : Physical and occupational therapy are an important part of recovery from a spinal cord injury. Stem cell therapies are in the early stages of use to aid in reducing inflammation around the injury and potentially regenerate the spinal cord Thoracic SCI Recovery An important part of the recovery and rehabilitation stage for thoracic spinal cord injury patients is physical therapy.
Additional Information about the Thoracic Spine Thoracic spinal cord injuries are rare and only account for 10 - 15 percent of all spinal cord injuries. See Vertebrae in the Vertebral Column. After branching from the spinal cord and traveling through the foramen, a thoracic nerve root branches into two different nerve bundles that feed into the nerves at the front ventral ramus and back dorsal ramus of the body.
At the T1 through T11 levels, the ventral ramus eventually becomes an intercostal nerve that travels along the same path as the ribs specifically between the innermost and internal intercostal muscles that connect adjacent ribs. At T12, the ventral ramus becomes a subcostal nerve that travels beneath the twelfth rib. At T1 through T12, the dorsal ramus goes into the back muscles and also provides sensation to the skin. The motor and sensory functions provided by a thoracic nerve root are determined by its vertebral level.
While these functions can slightly vary from person to person, they typically are as follows:. For example, T3 radiculopathy could radiate pain and other symptoms into the chest via the branch of the nerve root that becomes an intercostal nerve traveling along the route between the third and fourth ribs.
