General organization of a vertebra Flashcards
what are the three basic osseous parts of a vertebra?
vertebral body, vertebral arch, apophyseal region
What is the general shape of the vertebral body at each region of the spine?
cervical: rectangular
thoracic: triangular
lumbar: reniform
What is the name given to the compact bone at the superior and inferior surfaces of the vertebral body?
superior epiphyseal rim, inferior epiphyseal rim
What is the name given to the cartilage found at the superior and inferior surface of a developing vertebral body?
superior epiphyseal plate, inferior epiphyseal plate
What are the names of the openings found around the margins of the vertebral body?
nutrient foramina or vascular foramina
What large opening is usually observed at the back of the vertebral body
basivertebral venous foramen
What is the semicircular region of bone attached to the back of the vertebral body called?
vertebral arch
What is the name given to the anterior part of the vertebral arch?
pedicle
What is the name given to the posterior part of the vertebral arch?
lamina
What is the name given to the intermediate part of the vertebral arch where the transverse process and articular processes attach?
the lamina-pedicle junction
What is the name of the feature located at the upper and lower surfaces of the pedicle?
- the superior vertebral notch or superior vertebral incisor
- the inferior vertebral notch or inferior vertebral incisor
what is the generic orientation of the pedicle at each region of the spine?
Cervical- posterolateral
Thoracic- posterior, slight lateral
Lumbar- posterior
All lamina are orientated in what direction?
posterior and median
What is the name given to the overlap of laminae seen on X-ray?
shingling
What ligament will attach to the lamina?
ligamentum flavum
What is the name given to abnormal bone at the attachment site of the ligament flavor?
para-articular process
What classification of bone will para-articular processes represent?
accessory bone
What is the name given to the lamina-pedicle junction at the 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?
spinolaminar junction
Wha tis the name given to the tubular bone growth regions of the vertebral arch?
apophyseal regions
What names may be given to each apophysis of the spine?
transverse apophysis or transverse process; articular apophysis or articular process; spinous apophysis or spinous process
