The vertebral tubing usually consists of 33 vertebrae: 24 presacral vertebrae (7 cervical, 12 thoracic, and 5 lumbar) followed by the os (5 coalesced bone vertebrae) and the tail bone (4 frequently fused coccygeal vertebrae). A typical vertebra consists of (1) a body and (2) a vertebral arch, which has several processes (articular, transverse, and spinous) for articular and muscular attachments. The 24 presacral vertebrae let move and hence render the os article flexible. 'tween the gathering and the important is the bone foramen: the sum of the bone foramina constitutes the bone canal, which houses the skeletal structure cord (fig. In suburban area to the transverse and acanthoid processes, which tennis stroke as short levers, the 12 thoracic vertebrae are adjacent by joints with paired, long levers, namely the ribs. changelessness is provided by ligaments, muscles, and the sort of the bones. are used for the regions, and these are sometimes followed by V. The bodies of the vertebrae are separated from each other by intervertebral discs.
Herniated Discs: Definition, Progression, and Diagnosis
Herniation of the karyon pulposus (HNP) occurs when the nucleus pulposus (gel-like substance) breaks finished the ring fibrosus (tire-like structure) of an intervertebral saucer (spinal shock absorber). A herniated memory device occurs nigh oft in the lumbar region of the spine especially at the L4-L5 and L5-S1 levels (L = Lumbar, S = Sacral). This is because the lumbar spine carries most of the body's weight.
