Study Notes
Cervical Spine Biomechanics
- The cervical spine plays a crucial biomechanical role in supporting the head and facilitating movements such as flexion, extension, rotation, and lateral bending.
Protection of Structures
- The primary structure protected by the cervical spine is the spinal cord.
Intervertebral Disc Properties
- Intervertebral discs exhibit viscoelastic properties, which enable them to absorb and distribute mechanical stress.
Hysteresis and Ligamentous/IV Disc Properties
- Hysteresis refers to the phenomenon where the stress-strain response of ligamentous and intervertebral disc tissues varies depending on the loading and unloading cycles.
Creep in Intervertebral Discs
- Creep is a viscoelastic property of intervertebral discs, characterized by a gradual deformation in response to a constant load, resulting in permanent deformation over time.
