Day 8 (General organization of a vertebra) Flashcards
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 X-ray?
shingling
What is the name given to the lamina-pedicle junction at each region of the spine?
cervical-articular pillar
thoracic and lumbar- pars interartiularis
What is the name given to the vertebral arch-spinous process on lateral X-ray?
the spinolaminar junction
What is the generic orientation of the transverse process or transverse apophysis at each region of the spine?
cervical- anterolateral
thoracic- posterolateral
lumbar- 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/transverse apophysis to alter its initial direction in the thoracic region?
the growth of the lungs remodel the shape of the ribs which in turn push the transverse processes backward
What is the name given to the joint formed between articular facets of a vertebral couple?
the 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, and the ligamentum 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 or superior vertebral insicure
What will form the anterior boundary of a typical vertebral foramen?
the vertebral body of the segment above, the vertebral body of the segment below, the intervertebral disc, and the posterior longitudinal ligament
