Principle I: When the spine is in neutral, sidebending to one side will be accompanied by horizontal rotation to the opposite side. [2] This law is observed in type I somatic dysfunction, where more than one vertebra is out of alignment and cannot be returned to neutral by flexion or extension of the vertebrae. The involved group of vertebrae ...
The ligamenta flava (sg.: ligamentum flavum, Latin for yellow ligament) are a series of ligaments that connect the ventral parts of the laminae of adjacent vertebrae.They help to preserve upright posture, preventing hyperflexion, and ensuring that the vertebral column straightens after flexion.
The structure of these vertebrae is the reason why the neck and head have a large range of motion. The atlanto-occipital joint allows the skull to move up and down, while the atlanto-axial joint allows the upper neck to twist left and right. The axis also sits upon the first intervertebral disc of the spinal column.
The lumbar region is sometimes referred to as the lower spine, or as an area of the back in its proximity.. In human anatomy the five lumbar vertebrae (vertebrae in the lumbar region of the back) are the largest and strongest in the movable part of the spinal column, and can be distinguished by the absence of a foramen in the transverse process, and by the absence of facets on the sides of the ...
Many factors affect the flexibility of performers including age, genetics, stature, and adherence to rigorous physical training routines. Most contortionists are generally categorized as "frontbenders" or "backbenders", depending on the direction in which their spine is most flexible. Relatively few performers are equally adept at both.
Fewer traditional pensions. There has been a price to pay for ERISA’s guardrails. Employers gradually stopped offering traditional pension plans, partly because of those rigorous rules.
Scenario planning is as much art as science, and prone to a variety of traps (both in process and content) as enumerated by Paul J. H. Schoemaker. [14] More recently scenario planning has been discussed as a tool to improve the strategic agility, by cognitively preparing not only multiple scenarios but also multiple consistent strategies. [10]
