VERTEBRA STRCTURE AND FUNCTION(BIOMECHANIS OF SPINE)Physiotherapy Tutorial Instagram:   / _movementscience_   linked in :   / adhip-nadkarni-5b45241a6   twitter :   / adhip_nadkarni   summary of the video with the time for reference: 1.Spine 0:55 -33 vertebra -23 intervertebral disc -cervical vertebra-7 -thoracic vertebras-12 -lumbar vertebras-5 -sacral vertebras-5 -coccygeal vertebras-4 -primary curvature kyphotic curve at thoracic and sacral spine -secondary curvature lordotic curvature formed at cervical and lumbar spine 2.Vertebral body 3:40 -formed by trabecular bone and covered by cancellous bone -resists compressive forces due to arrangement of trabeculae 3.Pedicle 4:47 -connects the body to posterior elements -short and thick walls -transmits bending forces to the body 4.Articular surfaces 6:05 -Facet joints -2 superior facet -2 inferior facet -superior facet articulate with inferior fact of the next vertebra -forms an articular pillar 5.Spinous process 7:20 -posterior projection -forms from the lamina -provides attachment to the muscle and also serves as a bony block 6.Vertebral Foramen 9:22 -formed by lamia around it -protects the spinal cord and provides a passage 7.Lamina 9:41 -Pars inter-articularis goes through lot of bending forces and has high risk of stress fracture -these forces come from spinous process, transverse process, articular processes too 8.Transverse process 12:12 -lateral projection -Increases the moment arm #biomechanicsofspine #spinebiomechanics #vertebralcolumnbiomechanics
