Flashcards in General Organization of a Vertebra Deck (108)
What are the three basic osseous parts of a vertebra?
The vertebral body, vertebral arch, and the apophyseal regions
What is the general shape of the vertebral body at each region of the spine?
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 given to 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 name of the feature located at the upper and lower surfaces of the pedicle?
The superior vertebral notch or superior vertebral incisure
The inferior vertebral notch or inferior vertebral incisure
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 given to the overlap of laminae seen on an X-ray?
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
The 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 interartiularis
What is the name given to the junction of the vertebral arch - spinous process on a lateral x-ray?
The spinolaminar junction
What is the name given to the tubular bone growth regions of the vertebral arch?
The apophyseal regions
What names may be given to each apophysis of the spine?
The transverse apophysis or transverse processes, 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/transverse apophysis to alter its initial direction in the cervical region?
Cervical spinal nerves are pulled forward and downward to form the cervical and brachial nerve plexus 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?
What is the name given to the bone surface at the front of a zygapophysis?
The superior articular facet
What is the name given to the bone surface at the back of a zygapophysis?
The inferior articular facet
In the vertebral column, the part of the vertebra which lies anterior to to the zygapophysis is called the ___?
In the vertebral column, 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?
The superior articular process or superior articular apophysis
What is the name given to the part of the vertebra forming the post-zygapophysis?
The inferior articular process or inferior articular apophysis
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
