Flashcards in vertebral column part 3 ex. 1 QQ Deck (27):
what is the name given to the anterior part of the vertebral arch?
all lamina are oriented in what direction?
posterior and median
what is the name given to the overlap of laminae seen on x-ray?
what ligament will attach to the lamina?
what is the name given to abnormal bone at the attachment site of the ligamentum flavum?
what classification of bone will para-articular processes represent?
what is the name given to the lamina- pedicle junction at each region of the spine?
cervical- articular pillar
thoracic and lumbar- pars interarticularis
what is the name given to the junction of the vertebral arch- spinous process on lateral x-ray?
what is the name given to the tubular bone growth regions of the vertebral arch?
what are the names given to each apophysis of the spine?
transverse apophysis or transverse process
articular apophysis or articular process
spinous apophysis or spinous process
what is the generic orientation of the transverse process or transverse apophysis at each region of the spine?
all non-rib bearing vertebra of the spine retain what equivalent feature?
the costal element
what will cause the transverse process/ apophysis to alter in its initial direction in the cervical region?
cervical spinal nerves are pulled forward and downward 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 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?
what is the name given to the bone surface at the front of a zygapophysis?
superior articular facet
what is the name given to the bone surface at the back of a zygapophysis?
inferior articular facet
in the vertebral couple, the part of the vertebra which lies anterior to the zygapophysis is called the?
in the vertebral couple, the part of the vertebra which lies posterior to the zygapophysis is called the?
what is the name given to the part of the vertebra forming the pre-zygapophysis?
superior articular process or apophysis
what is the name given to the part of the vertebra forming the post-zygapophysis?
inferior articular process or apophysis
what will form the posterior boundary of a typical intervertebral foramen?
inferior articular process/post- zygapophysis
superior articular process/ pre-zygapophysis
what will form the anterior boundary of a typical intervertebral foramen?
vertebral body of the segment above
vertebral body of segment below
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 name given to the normal overlap of spinous processes or spinous apophyses as seen on x-ray?
what is the name given to the round elevation at the tip of the spinous process?
