What is the name given to the cartilage found at the superior and inferior surface of a developing vertebral body?
Superior epiphyseal plate and Inferior epiphyseal plate
What are the ages of appearance and the events occurring at each step in the formation of bone at the superior and inferior surface of the vertebral body?
Ages 7-9 years: Appearance of epiphyseal plate centers of ossification
Age 12 years: Formation of the epiphyseal RING
Age 15 years: Formation of the epiphyseal RIM
What is the generic orientation of the pedicle at each region of the spine? (Cervical, Thoracic, Lumbar)
Cervical: Posterolaterally
Thoracic: Posterior, Slightly lateral
Lumbar: Posterior
What is the name given to abnormal bone at the attachment site of the ligamentum flauvum?
para-articular process
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, Thoracic, Lumbar)
Cervical: Articular Pillar
Thoracic and Lumbar: Pars Interarticularis
What is the generic orientation of the transverse processes and transverse apophysis at each region of the spine? (Cervical, Thoracic, Lumbar)
Cervical: Anterolateral
Thoracic: Posterolateral
Lumbar: Lateral
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 by the 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 anterior boundary of a typical intervertebral foramen?
The vertebral body of the segment above, the vertebral body of the segment below, the intervertebral disc, and the posterior longitudinal ligament
What is the name given to the normal overlap of spinous processes or spinous apophyses as seen on X-ray?
Imbrication
What is the orientation of the spinous process/spinous apophysis at each region of the spine?
cervical-slight angle inferiorly
thoracic-noticeable angle inferiorly
lumbar-no inferior angle
What is the name given to the union of all vertebral formina into an apparent vertical cylinder?
the vertebral canal or spinal canal
What neural structures will occupy the vertebral foramen until the level of L2?
the spinal cord/spinal medulla/medulla spinalis, the proximal part of the peripheral nerve system, and the meninges
What is the typical shape/outline of the vertebral foramen at each region of the spinal column/vertebral column?
Cervical, lumbar, sacrum = triangular
Thoracic = oval
Identify the meninges of the spinal cord/spinal medulla/medulla spinalis and the commonly accepted meaning of each.
Dura mater - tough mother, arachnoid mater - spider mother, pia mater - tender or delicate mother
Name and locate each space formed between the osseous vertebral foramen and the spinal cord spinal medulla/medulla spinalis
Epidural space - between the vertebral foramen and the dura mater
Subdural space - between the dura mater and the arachnoid mater
Subarachnoid space - between the arachnoid mater and the pia mater
Which of the contents of the epidural space will be found near the vertebral body?
Anterior spinal canal artery & plexus, anterior internal vertebral venous plexus, basivertebral veins, recurrent meningeal/sinu-vertebral/sinus vertebral nerve, posterior longitudinal ligament, Hoffmann ligament
What are the branches of the spinal artery?
Osseous arteries, anterior spinal canal artery, posterior spinal canal artery, anterior medullary feeder arteries, posterior medullary feeder arteries, neural artery
What forms the arterial vasa corona below C6?
A median anterior spinal artery, right and left posterior spinal arteries, and 3 communicating arteries
Which vessel will supply the dorsal/posterior nerve root ganglion?
Posterior distal radicular artery
