Study Notes
Characteristics of Vertebral Column
- The thoracic region of the vertebral column is characterized by posterior convexity and anterior concavity.
Comparison of Spinal Column with Normal Curves and Straight Rod
- A spinal column with normal curves is able to resist axial compression better than a straight rod, according to Kapandji.
Composition of Vertebra
- The posterior portion of a typical vertebra consists of pedicles and posterior elements.
Definition of Spinal Segment
- A spinal segment is defined as any two adjacent vertebrae, the intervening intervertebral disc, and all the soft tissues that secure them together.
Contact Forces in Vertebral Column
- The lumbosacral junction (L5 and S1) sustains the largest contact forces in the vertebral column.
Test your knowledge of the general structure and function of the vertebral column, including the characteristics and functions of the thoracic, sacral, cervical, and lumbar spines. Explore the biomechanics and anatomical features related to spinal curves and intervertebral discs.
