The thoracic vertebrae are a group of twelve small bones that form the vertebral spine in the upper trunk. They form the region of the spinal column inferior to the cervical vertebrae of the neck and superior to the lumbar vertebrae of the lower back.Correspondingly, what is the function of the thoracic vertebrae?
Thoracic (mid back) - the main function of the thoracic spine is to hold the rib cage and protect the heart and lungs. The twelve thoracic vertebrae are numbered T1 to T12. The range of motion in the thoracic spine is limited. Lumbar (low back) - the main function of the lumbar spine is to bear the weight of the body.
Secondly, which thoracic vertebrae are typical? Given the twelve thoracic vertebrae are largely similar, most are considered typical thoracic vertebrae with the exceptions T1 and T9 to T12.
Also, how are thoracic vertebrae different?
The body of a thoracic vertebra is somewhat “heart-shaped,” and is larger than the cervical but smaller than the lumbar vertebrae in size. The body also has small, smooth, and somewhat concave costal facets for the attachment of the ribs. The costal facets are also slightly different between the vertebrae.
How many articulations does a thoracic vertebrae have?
Thoracic vertebrae have articular facets on their lateral sides, which support the ribs. Each typical rib has two articulations with vertebrae: one on the side of adjacent thoracic bodies and one at the end of the thoracic transverse process.

What does thoracic pain feel like?
The pain may increase with certain positions or movements of the neck.

The short answer, in most cases, is no. Most people with thoracic spine pain get better without treatment in a couple of weeks. However, thoracic back pain is more likely to be due to a serious cause than pain in other areas of the spine.What type of bone is the thoracic vertebrae?
Thoracic Vertebrae. 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.What is the largest thoracic vertebrae?
Thoracic Spine T1 is the smallest and T12 is the largest thoracic vertebra. The thoracic vertebrae are larger than the cervical bones and have longer spinous processes.What features on thoracic vertebrae are lacking on other vertebrae?
Thoracic vertebrae lack transverse foramina. Spinous process. Thoracic spinous processes are long, straight, and narrow compared to the short, bifid cervical spinous processes and the hatchet-shaped lumbar spinous processes.Where is Thoracic located?
The thoracic spine is located in the chest area and contains 12 vertebrae. The ribs connect to the thoracic spine and protect many vital organs. Learn what conditions can affect your thoracic spine in our Upper Back Pain Center. Next is the lumbar spine.What are the 12 thoracic vertebrae?
In human, thoracic vertebrae consists of 12 bones. From top to down, T1, T2, …, T12. A typical thoracic vertebra, seen from lateral side. By convention, the human thoracic vertebrae are numbered T1–T12, with the first one (T1) located closest to the skull and the others going down the spine toward the lumbar region.Can you have 13 thoracic vertebrae?
The most common variabilities reported in thoracolumbar anatomy are the presence of 13 rib-bearing thoracic vertebrae with four lumbar-type vertebrae and the presence of 12 rib-bearing thoracic vertebrae with six lumbar-type vertebrae (3).How do you know if you have lumbar and thoracic?
A typical thoracic vertebra is distinguished by its long, downward projecting spinous process. Thoracic vertebrae also have articulation facets on the body and transverse processes for attachment of the ribs. Lumbar vertebrae support the greatest amount of body weight and thus have a large, thick body.What do thoracic vertebrae articulate with?
Introduction to the Thoracic Vertebrae: articulates with a pair of ribs at facets (or small depressions) on the vertebral bodies and transverse processes (except at T11 and T12). The thoracic vertebra articulating with a pair of ribs.What muscles attach to the thoracic vertebrae?
Muscles. Thoracic vertebrae provide points of attachment for numerous muscles: erector spinae, interspinales, intertransversarii, latissimus dorsi, multifidus, rhomboid major, rhomboid minor, rotatores, semispinalis, serratus posterior superior/inferior, splenius capitis, splenius cervicis, and trapezius.How do I know if I have t12 vertebrae?
Count up from L4 to identify L1. Alternatively you could identify T12. The spinous process of T12 is typically smaller than L1. T12 can also be verified by location of the 12th rib and the attachment site at T12 then go down to the next level to find L1.Where do ribs attach to thoracic vertebrae?
Each rib is a curved, flattened bone that contributes to the wall of the thorax. The ribs articulate posteriorly with the T1–T12 thoracic vertebrae, and most attach anteriorly via their costal cartilages to the sternum.
