In human anatomy, the five vertebrae are between the rib cage and the pelvis.They are the largest segments of the vertebral column and are characterized by the absence of the foramen transversarium within the transverse process (since it is only found in the cervical region) and by the absence of facets on the sides of the body (as found only in the thoracic region).
The thoracolumbar fascia (lumbodorsal fascia or thoracodorsal fascia) is a complex, [1]: 1137 multilayer arrangement of fascial and aponeurotic layers forming a separation between the paraspinal muscles on one side, and the muscles of the posterior abdominal wall (quadratus lumborum, and psoas major [1]: 1137 ) on the other.
The thoracolumbar spine or thoracolumbar division refers to the thoracic and lumbar vertebrae together, and sometimes also their surrounding areas. The thoracic vertebrae attach to ribs and so have articular facets specific to them; these are the superior, transverse and inferior costal facets. As the vertebrae progress down the spine they ...
Adopting a forward head and rounded shoulders posture places increased stress on the neck (cervical spine), mid-back (thoracic spine) and low back (lumbar spine), Dr. Halfman explains.
Because the vertebral column will outgrow the spinal cord during child development, by adulthood the spinal cord often ends at the upper lumbar spine (at around L1/L2 level), the lower end of the spinal canal is occupied by a ponytail-like bundle of spinal nerves descriptively called cauda equina (from Latin "horse's tail"), and the sacrum and ...
Images are most often taken of the lumbar spine due to spondylolisthesis most commonly involving the lumbar region. [7] Images of the thoracic spine can be taken if a patient's history and physical suggest thoracic involvement.
To image the thoracic spine, lumbar puncture is done and contrast medium is injected into the puncture site. The subject lie down on one side, then head of the table is lowered, with subject's head supported by bolster or pad to prevent the contrast from flowing up into the neck.
The twelfth thoracic vertebra has the same general characteristics as the eleventh, but may be distinguished from it by its inferior articular surfaces being convex and directed lateralward, like those of the lumbar vertebrae; by the general form of the body, laminae, and spinous process, in which it resembles the lumbar vertebrae; and by each ...
