Where is the T11 and T12 vertebrae located?
Where is the T11 Vertebra Located? The T11 vertebrae location is near the bottom of the thoracic spine, at the first “false” ribs. It rests between the T10 and T12 vertebrae. Where is the T12 Vertebra Located? The T12 vertebra sits right above the lumbar spinal column. It is the largest and most inferior of the thoracic spinal vertebrae.
Where is T12 L1 located?
The place where the bottom thoracic vertebra (T12) meets the top lumbar vertebrae (L1) is called the thoracolumbar junction. This junction is also an attachment point for many of the body’s key muscles. My favorite muscle, the psoas, attaches to both T12 and L1. The large back muscles the latissimus dorsi and trapezius have attachments on T12.
Where is the T11 and T12 vertebrae?
They are called T11 and T12. Your lowest 2 ribs are attached to these vertebrae. The areas of the body and functions of the body controlled by the nerves exiting these vertebrae control: Kidneys, Ureters, Small Intestines, Colon, Uterus, Lymph Circulation, and the Buttocks.
What are symptoms of thoracic compression fracture?
- Slowly worsening back pain — lying on your back may relieve the pain and standing may make it worse
- Decreased height
- Stooped-over posture
- Numbness or tingling, weak muscles, problems walking and (possible) trouble controlling your bowels or bladder because of nerve damage

A minor injury will result in minor symptoms such as weakness, numbness, as well as partial or complete lack of muscle control over only one side of the body. Severe damage to this vertebra can result in complete paraplegia .
Where is the spinal cord located?
The spinal cord is the main bundle of nerves that runs from the base of the brain all the way down through the cervical spine and thoracic spine before splitting into a bundle of nerve roots (cauda equina) in the lumbar spine. The brain exchanges electrical signals with the rest of the body via the spinal cord.
How many nerve roots are there in the thoracic spine?
Thoracic Spinal Nerves. The thoracic spine has 12 nerve roots (T1 to T12) on each side of the spine that branch from the spinal cord and control motor and sensory signals mostly for the upper back, chest, and abdomen. The thoracic spine (highlighted) spans the upper and mid-back. It includes twelve vertebrae named T1 through T12.
How many thoracic nerves are there?
Each thoracic spinal nerve is named for the vertebra above it. For example, the T3 nerve root runs between the T3 vertebra and T4 vertebra. There are 12 thoracic spinal nerve root pairs (two at each thoracic vertebral level), starting at vertebral level T1-T2 and going down to T12-L1.
What nerves feed into the ventral ramus?
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 ...
What is spinal cord injury?
Spinal cord injuries are usually classified based on the spinal nerve root level where function is reduced or completely lost. For example, a T6 spinal cord injury would impair or lose function at the T6 nerve root level and below.
What nerve travels between the ribs?
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.

The T1 nerve roots affect sensation in your inner forearm and the ability to spread your fingers ...
Where do T6 nerve roots affect?
The T6 nerve roots generally affect sensation around the top of the abdomen. Each consecutive set of nerve roots innervates a lower portion of the trunk. Individuals with lower-level thoracic spinal cord injuries generally have enough trunk control that they can sit upright and perform transfers independently.
How does spinal cord injury recovery work?
Spinal cord injury recovery primarily focuses on promoting neuroplasticity through massed practice. Neuroplasticity is the spinal cord’s ability to rewire itself and make adaptive changes so that functions affected by damage can be relearned. However, only undamaged neural pathways are capable of utilizing neuroplasticity. Therefore, those with milder SCIs generally have a better recovery prognosis.
How does spinal cord injury affect functional abilities?
It’s important to remember that while the level of the SCI provides general information regarding functional outcomes, the severity of the spinal cord injury greatly affects the functional abilities retained following the injury. The affected motor control and sensation of someone with any specific level of SCI can vary significantly, resulting in differing functional abilities.

How many vertebrae are in the thoracic spine?
Your thoracic spine is located in the middle of your back and consists of 12 vertebrae. It’s also home to 12 nerve roots (T1-T12) on each side of your spine that run from the spinal cord and control functions and sensory signals in your abdomen, chest and upper back.
What nerves are involved in thoracic radiculopathy?
T9, T10, T11 and T12 – These lead into your abdomen and your lower back. Compression or irritation of these nerves is classified as thoracic radiculopathy, and it can lead to a number of symptoms based on the extent and location of the impingement.
What causes radiculopathy in the thoracic area?
Two of the most common causes of thoracic radiculopathy are from compression caused by a herniated disc or from a narrowing of the spinal foramen , an opening through which these nerves pass. With that said, it’s also important to note that a severe intercostal muscle sprain can also lead to nerve compression or damage.
What are the different types of spinal nerves?
Each one of your spinal nerves controls different functions and sensations, so the symptoms you experience can vary based on the exact level of damage. Before we touch on the symptoms, let’s explain where each one of these nerves traverses: 1 T1 and T2 – These lead into nerves that go into the top of your chest and into the arms and hands. 2 T3, T4 and T5 – These lead into the chest wall and help regulate breathing. 3 T6, T7 and T8 – These lead into your chest and abdomen. 4 T9, T10, T11 and T12 – These lead into your abdomen and your lower back.
What nerves go into the top of your chest and into your arms and hands?
T1 and T2 – These lead into nerves that go into the top of your chest and into the arms and hands.
What tests can be done to diagnose nerve compression?
Finally, they’ll likely order some imaging tests. An X-ray, MRI, CT scan or EMG can all help to isolate the location of the nerve compression. Once the source of irritation has been identified, your spine specialist will begin to develop an individualized treatment plan.
What is it called when a bone in the spine collapses?
When a bone in the spine collapses, it is called a vertebral compression fracture. These fractures happen most commonly in the thoracic spine (the middle portion of the spine), particularly in the lower vertebrae of the thoracic spine. The purpose of this document is to help you understand:
How to treat a broken vertebra?
You will most likely have to limit your normal activities. You should avoid any strenuous activity or exercise. You will definitely need to avoid heavy lifting and anything else that might place too much strain on your fractured vertebra. If you are elderly, your doctor might also put you on bed rest. Older bones take longer to heal and are typically thinner and weaker than younger bones. Treat this fracture as you would any other broken bone, carefully and seriously.
What causes the spine to bend forward?
This causes the spine to bend forward concentrating the pressure on the front part of the spine - the vertebral bodies. The fracture occurs when the bone actually collapses and the front (anterior) part of the vertebral body forms a wedge shape. The cancellous bone on the inside of the vertebral body is crushed, or compressed.
Why do vertebrae fracture?
Vertebra fractures are usually due to conditions such as: osteoporosis (a condition which weakens the bones), a very hard fall, excessive pressure, or some kind of physical injury.
How to remove pressure from spinal cord?
When surgery is necessary to remove pressure from the spinal cord, your surgeon may suggest an operation from the front of the spine. During an anterior approach an incision is made in the chest to allow the surgeon to see the front of the spine and locate the vertebra that has been crushed. Once the vertebra has been located, the bone fragments may be removed to remove the pressure from the spinal cord. Once this has been accomplished, a spine fusion is usually performed.
How long does it take for a vertebral fracture to heal?
Vertebral fractures usually take about three months to fully heal. X-rays will probably be taken monthly to check on the healing progress.
Can a fall cause a fracture of the spine?
Trauma to the spinal vertebrae can also lead to minor or severe fractures. Such trauma could come from a fall, a forceful jump, a car accident, or any event that stresses the spine past its breaking point.
