What are the 12 thoracic?
The twelve thoracic vertebrae are strong bones that are located in the middle of the vertebral column, sandwhiched between the cervical ones above and the lumbar vertebrae below. Like typical vertebrae, they are separated by intervertebral discs.
Which vertebral segment has 12 bones?
Thoracic
Vertebral Column
| Term | # of Vertebrae | Body Area |
|---|---|---|
| Thoracic | 12 | Chest |
| Lumbar | 5 or 6 | Low Back |
| Sacrum | 5 (fused) | Pelvis |
| Coccyx | 3 | Tailbone |
What are the 12 pairs of thoracic nerves?
Your thoracic spine consists of 12 vertebrae numbered T1 to T12. Each number corresponds with the nerves in that section of your spinal cord, as well. These nerves branch off of your spinal cord and supply sensation (feeling) and movement to certain areas of your body.
How are the 12 thoracic vertebrae unique?
The thoracic vertebrae are a group of twelve small bones that form the vertebral spine in the upper trunk. Thoracic vertebrae are unique among the bones of the spine in that they are the only vertebrae that support ribs and have overlapping spinous processes.
Where is the 12th thoracic vertebrae?
The T12, or twelfth thoracic vertebra is the largest of all your thoracic vertebrae, and is the lowermost in the back. It’s designed to bear the weight of your spine, and is the strongest of all vertebrae in the region, but it’s also the most prone to injuries from stress.
How are thoracic vertebrae 11 and 12 different?
The eleventh thoracic vertebra (T-11) has an intact, superiorly placed costal facet on each side of the vertebral body, but no costal articulation on the transverse processes. The twelfth thoracic vertebra (T-12) resembles T-11, but the inferior articular facets assume the lumbar pattern.
Where is the 12th vertebrae located?
How many pairs of thoracic nerves are there?
12 thoracic nerve pairs
There are 12 thoracic nerve pairs. The first nerve root exits between the T1 and T2 vertebrae.
What is the job of the 12 thoracic vertebrae?
The thoracic vertebrae function to support the back. Their articulations with the ribs allow them to provide a protective cage around the delicate organs of the thorax, including the heart and lungs.
Where is my 12th 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. The T12 vertebrae location is between the T11 vertebra and the first lumbar vertebra, L1, in the trunk region.
Where is the 11 and 12 vertebrae?
thoracic spine
The thoracic spinal vertebrae consist of 12 total vertebrae and are located between the cervical vertebrae (which begin at the base of the skull) and the lumbar spinal vertebrae. The eleventh thoracic vertebra (T11) is located near the bottom of the thoracic spine.
How many thoracic vertebrae are there?
12 vertebrae
The thoracic region contains 12 vertebrae, denoted T1-T12. The intervertebral discs, along with the laminae, pedicles, and articular processes of adjacent vertebrae, create a space through which spinal nerves exit.
What is T11 and T12?
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.
Can you have only 11 thoracic vertebrae?
In humans, there are twelve thoracic vertebrae and they are intermediate in size between the cervical and lumbar vertebrae; they increase in size going towards the lumbar vertebrae, with the lower ones being much larger than the upper.
What does the T12 nerve control?
The T12 nerve roots innervate the very lower abdominal muscles. Therefore, individuals with T12 SCIs will focus on rehabilitation for the lower half of their body. Your spinal cord relays messages between your brain and body.
What is 12th thoracic vertebrae?
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.
