lateral curvature
Function
supports the thoracic cage muscle attachment protection of spinal cord shock absorption movement
Articular process
transmit weight enable movement limit movement control direction 2 superior and 2 inferior in cervical spine enable rotation but limited rotation in lumbar spine due to orientation of joint
Transverse process
projection laterally from junction pedicles and laminae
lever for muscles and ligaments to side flex and rotate the trunk
Spinous process
projects dorsally
vary in size shape and direction
levers for muscles for spine extension
Zygopophyseal joint
synovial joints
articulation between the superior and inferior articular process
articulatar cartilage
synovial membrane and capsule
cervical- 45 degrees upwards
thoracic- vertical backwards
lumbar-vertical inwards
Ligaments
Anterior longitudinal ligament posterior longitudinal ligament ligamentus flavum interspinous ligament supraspinous ligament ligamentum nuchar intertransverse ligament
Thoracic cage
protection of vital organs
provides muscles attachment
assist respiration
costo-vertebral jont
synovial plane joint
head of rib articulates with costal facet on vertebrae
1, 11 and 12 heads only articulate with corresponding vertabra
2-10 articulate with corresponding vertebra and vertebra above
costo-transverse
synovial plane joint
tubercle of rib with transverse process of corresponding vertabre
Costochondral
primary cartilaginous joint
lateral end on costal cartilage and sternal end of rib
Interchondral
between costal cartilage
to false rib
1st sternocostal
primary cartilaginous joint
1st costal cartilage and manubruim of sternum
sternocostal
synovial plane joint
costal cartilage to body of the sternum
sterno-clavicular
saddle
Manbrio-sternal
symphysis
xiphisternal
synchondrosis
Lumbar
flexion greater than extension
extension
rotation limited by orientation of the zygophyseal joint horizontal articular surface
lateral flexion
Thoracic
less mobile than cervical and lumbar
rotation greatest range
flexion resrticting bony apposition of spinous processes
lateral flexion restricted by bony apposition of the ribs
inter-vertebral joint
symphysis joint vertebral bodies articulation cartilaginous vertebral hyaline end plate intervertebral disc
