The vertebral newspaper column normally consists of 33 vertebrae: 24 presacral vertebrae (7 cervical, 12 thoracic, and 5 lumbar) followed by the sacrum (5 fused os vertebrae) and the tail bone (4 frequently fused coccygeal vertebrae). A veritable bone consists of (1) a dead body and (2) a bone arch, which has several processes (articular, transverse, and spinous) for articular and powerful attachments. The 24 presacral vertebrae allow movement and hence render the vertebral indian file flexible. Between the body and the arch is the vertebral foramen: the sum of the os foramina constitutes the vertebral canal, which houses the spinal cord (fig. In addition to the transverse and spinous processes, which work as short-range levers, the 12 thoracic vertebrae are affined by joints with paired, long levers, namely the ribs. firmness is provided by ligaments, muscles, and the pattern of the bones. are used for the regions, and these are sometimes followed by V. The bodies of the vertebrae are separated from each otherwise by os discs.
Herniated Discs: Definition, Progression, and Diagnosis
Herniation of the centre pulposus (HNP) occurs when the cell nucleus pulposus (gel-like substance) breaks through with the anchor ring fibrosus (tire-like structure) of an intervertebral sound recording (spinal fighting absorber). A herniated record occurs nigh often in the lumbar region of the vertebral column particularly at the L4-L5 and L5-S1 levels (L = Lumbar, S = Sacral). This is because the body part spine carries most of the body's weight.
