Why the back of the child?

Abstract:
An international congress about "the back of children and teenagers and the prevention of backache" was held in March 1999 in Grenoble (France). Beside specific low back pain following progressive and growth diseases, special attention was paid to non-specific low back pain (LBP). Some epidemiological data show a high incidence of LBP during and after the rapid growth phase, with the concomitant possibility of continued or recurrent evolution. MRI studies reveal frequent signs of disc degeneration: they start after the growth phase, spread during adolescence and are often correlated with backache. An immunohistological study seems to confirm the presence of degenerative-type alterations and changes in collagen in the vertebral plates and nucleus of juvenile spine. These data must be confirmed, and their relation to natural history and prognosis of juvenile LBP have to be clarified by longitudinal studies.

Vertebral Column: Regions and Curvature
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form the...

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
Rigid Body Equilibrium Problems - II
Consider two children sitting on a seesaw, which has negligible mass. The first child has a mass (m1) of 26 kg and sits at point A, which is 1.6 meters (r1) from the pivot point B; the second child has a mass (m2) of 32 kg and sits at point C. How far from the pivot point B should the second child sit (r2) to balance the seesaw?
Introduction to the Skeletal System
Components of the Skeletal System
Bone, or osseous tissue, is a hard connective tissue that forms an internal support structure for the human body. Bones shield vulnerable organs and soft tissue from external forces. For example, the vertebral bones protect and support the spinal cord.
Cartilage, a semi-rigid connective tissue found in regions such as...
