sept 13 Flashcards
ligament. travels/is anchored to the anterior aspect of vertebral bodies and IVDs from sacrum to occiput
anterior longitudinal ligament
ligament that stabilizes intervertebral joints and checks hyperextension of the spine
anterior longitudinal ligament
joints. inferior articular facet of one vertebra articulates with the superior articular facet of the next inferior vertebra
facet joints
what type of joint are facet joints?
synovial plane
orientation of cervical facet joints
oblique (higher anteriorly)
orientation of thoracic facet joints
more in the frontal plane
orientation of lumbar facet joints
more in the saggital plane
available movements of facet joints
flexion/extension, rotation, lateral flexion
3 factors affecting ROM of facet joints
size and shape of IVDs, angle of facet joints, laxity (looseness) of ligaments/joint capsules
ligament. attaches from lamina to lamina from the sacrum up to C1
ligamenta flava
ligament. helps preserve normal spinal curves, helps return spine to normal position after flexion
ligamenta flava
ligaments found between SPs
interspinous ligaments
function of interspinous ligaments
limit flexion
ligaments found posteriorly along tips of SPs from C7 to sacrum
supraspinous ligaments
function of supraspinous ligaments
limit flexion
ligament from c7 to back of the skull
ligamentum nuchae
thickening of the interspinous/supraspinous ligaments
ligamentum nuchae
joint. the only bony articulation between the upper limb and axial skeleton
sternoclavicular joint
joint. clavicle articulates with the manubrium and costal cartilage of rib 1
sternoclavicular joint
what kind of joint is the sternoclavicular joint
synovial saddle
function of sternoclavicular joint
shock absorber for forces along clavicle
available movements of sternoclavicular joint
elevation/depression, protraction/retraction, rotation
ligament. attaches first rip to sternal end of clavicle
costoclavicular ligament
function of costoclavicular ligament
checks all movements of the clavicle except inferior
ligament. connects the 2 SC joints across the manubrium
interclavicular ligament
sternoclavicular ligaments exist on what facets of the SC joint
anterior and posterior
joint. manubrium articuates with the body of the sternum
manubriosternal joint
what type of joint is the manubriosternal joint?
cartilagenous
available movements of manubriosternal joint
movement during respiration
joint. body of the sternum articulates with the xiphoid process
xiphisternal joint
what type of joint is the xiphisternal joint
cartilagenous
joints. cartilages of first 7 ribs and costal notches on lateral borders of sternum
chondrosternal joints
what types of joint are the chondrosternal joints of the first rib and manubrium
cartilaginous
what type of joint are the chondrosternal joints of ribs 2-7
synovial
ligaments. Thin fan-shaped ligaments from both anterior and posterior surfaces of the costal cartilage of ribs 1-7 to anterior and posterior surfaces of the sternum
radiate sternocostal ligaments
function of radiate sternocostal ligaments
limit rib movement, stabilize rib attachments
joints. lateral end of each costal cartilage fits into a cup-shaped anterior end of its associated rib
costochondral joints
what type of joint are the costochondral joints
cartilagenous
how are costochondral joints supported/bound?
periosteum
joints. the adjacent borders of the costal cartilages articulate
interchondral joints
what type of joint are the interchondral joints
synovial
how are the interchondral joints supported?
interchondral ligaments
joints. head of the rib articulates with the facets on the side of the vertebral body
costovertebral joints
the superior head facet of the head of the rib articulates with what facet of which vertebral body
inferior facet of superior body
the inferior head facet of the head of the rib articulates with what facet of which vertebral body
superior facet of inferior body
what type of joint are the costervertebral joints
synovial plane
ligament. head of the rib to the 2 vertebral bodies and disc in between
radiate ligament
joints. facet on the tubercle of the rib articulates with the costal facet on the associated TVP
costotransverse joints
what type of joint are the costotransverse joints
synovial plane
ligament. connects the neck of a rib to the next superior TVP
superior costotransverse ligament
ligament. connects the tubercle of a rib to the associated TVP
lateral costotransverse ligament
