Orginization of Vertebra Flashcards
What is the name given to the compact bone at the superior and inferior surfaces of the vertebral body?
superior and inferior epiphyseal rim
What is the general shape of the Vertebral body at each region of the spine?
C - rectangular
T - Triangular
L - reniform
What is the name given to the intermediate part of the vertebral arch where transverse process and articular process attach?
the lamina-pedicle junction
what is the generic orientation of the pedicle at each region of the spine?
C - posterolateral
T - posterior, slight lateral
L - posterior
what ligament will attach to the lamina?
the ligamentum flavum
what is the name given to abnormal bone at the attachment site of the ligamentum flavum?
para-articular process
What classification of bone will para-articular processes represent?
accessory bone
What is the name given to the overlap of laminae seen on xray?
shingling
What is the name given to the lamina-pedicle junction at each region of the spine?
C - articular pillar
T/L - pars interarticularis
What is the name given to the junction of the vertebral arch - spinous process on lateral xray
the spinolaminar junction
What is the generic orientation of the transverse process or transvers apophysis at each region of the spine?
C - anterloateral
T - posterolateral
L - lateral
all non rib bearing vertebra of the spine retain what equivalent feature?
the costal element
What will cause the transverse process/transverse apophysis to alter its initial direction in the cervical region.
cervical spinal nerves are pulled forward to form the cervical and brachial nerve plexuses thus remodeling the transverse process to accommodate their new position
What will cause the transverse process/apophysis to alter its initail direction in the thoracic region?
the growth of the lungs remodels the shape of the ribs which in turn push the transverse process backwards.
What is the name given to the joint formed between articular facets of a vertebral couple?
zygapophysis
What will form the posterior boundary of a typical intervertebral foramen?
the inferior articular process/post-zygapophysis
the superior articular process/pre-zygapophysis
the capsular ligament
the ligaementum flavum
What will form the superior boundary of a typical intervertebral foramen
the inferior vertebral notch or inferior vertebral incisure
What will form the inferior boundary of a typical intervertebral foramen?
the superior vertebral notch/incisure
What will form the anterior boundary of a typical intervertebral foramen
the vertebral body of the segment above and below
intervertebral disc
posterior longitudinal ligament
what is the name given to the normal overlap of spinous processes/apophyses as seen on xray?
imbrication
What is the method of calculating the angle of the spinous process/apophysis?
calculate the angle formed between the undersurface of the spinous process/apophysis and the horizontal plane
What is the orientation of the spinous process/apophysis at each region of the spine?
C - Slight angle inferiorly
T - noticeable angle inferiorly
L - no inferior angle
