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.
What nerves are affected by T12?
What does the t12 nerve control? 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. Click to see full answer. Similarly, what muscles are innervated by t12?
What does T12 stand for?
What does t12 stand for? The "T" in T5 indicates the bulb is tubular shaped, while the "5" denotes that it is five eighths of an inch in diameter. The other common lamps are the larger T8 (eight eighths inch = 1") and T12 (twelve eights inch = 1½" tubes).
What is the explanation for T1 through T12?
T1-T12 (thoracic vertebrae): The symbols T1 through T12 represent the 12 thoracic vertebrae. The thoracic vertebrae are situated between the cervical (neck) vertebrae and the lumbar vertebrae.. The thoracic vertebrae provide attachment for the ribs and make up part of the back of the thorax (the chest).
What is wrong with T12 tubes?
T12 lamps are of a higher wattage than T8 lamps so you risk shortening the lifespan of the ballast if the wrong lamps are used. I’ve seen installations where T12 lamps have been operated on electronic T8 ballasts and they fail to deliver their full rated light output.
What does your T12 control?
The region of your spinal cord protected by this vertebra controls your abdominal muscles, lower back, stability and support. Unfortunately, pain from a T12 injury can be tricky to diagnose as it can radiate to other areas of your body and not be centered where the injury actually is.

What does T11 and T12 control?
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 organs are affected by thoracic spine?
The nerves that branch off from your spinal cord in your thoracic spine transmit signals between your brain and major organs, including your:Lungs.Heart.Liver.Small intestine.
Where is the T12 located?
The T12 vertebra is located in the spinal column of the thoracic (or trunk) region inferior to the T11 vertebra and superior to the first lumbar (L1) vertebra. Continue Scrolling To Read More Below...
What are the joints in the T11 and T12?
The joints formed between T11 and T12 are classified as planar joints , and allow the bones to glide along a plane relative to one another. At the bottom of T12, a pair of inferior articular processes descends to meet the superior articular processes of the L1 vertebra.
What are the two pairs of articular processes that extend vertically from the vertebral arch?
Extending vertically from the vertebral arch are two pairs of articular processes that form joints with the neighboring vertebra and help to stabilize the spine. The superior articular processes extend superiorly to meet the inferior articular processes of the T11 vertebra.
Which thoracic vertebra is the strongest?
The twelfth thoracic vertebra (or the T12 vertebra) is the largest and most inferior of the thoracic vertebrae. T12 bears the most weight of any thoracic vertebra, making it the strongest thoracic vertebra, but also the most susceptible to stress-related injuries. In many ways, the T12 is a hybrid vertebra with the anatomical features ...
Is T12 a vertebral body?
The vertebral body is larger and wider in T12 than in the other thoracic vertebrae and more closely resembles the vertebral bodies of the lumbar vertebrae. It is flat on top and bottom, convex anteriorly, and slightly concave posteriorly. Most of the osseous tissue of T12 is contained within the centrum, which serves to support the body’s weight.
What nerve goes into the back muscles?
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.
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.
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 ...
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.

See Radiculopathy, Radiculitis and Radicular Pain. It should also be noted that a severe strain of a muscle between ribs (intercostal muscle) may cause an intercostal nerve to become inflamed, painful, and possibly make breathing more difficult. See Upper Back Pain from Intercostal Muscle Strain. advertisement.
Can a thoracic nerve cause pain?
How Thoracic Nerves Can Become Painful. If any of the thoracic nerves become inflamed, such as from a thoracic herniated disc or a narrowing of the foramen, thoracic radiculopathy can develop with symptoms of pain, tingling, numbness, and/or weakness radiating along the nerve root.
