Spine Disorders Flashcards
Name the five parts of the vertebrae which protects the spinal cord.
Cervical
Thoracic
Lumbar
Sacrum
Coccyx
RECAP- which regions of the vertebrae have lordosis curvatures?
Lumbar
Cervical
RECAP- which regions of the vertebrae have kyphosis curvatures?
Thoracic
Sacral
What is the purpose of the curvatures of the spine?
Allows for distribution of weight
There are three regions of the cervical spine- which region is found at C1-2?
Atlanto-axial joint
There are three regions of the cervical spine- which region is found at C3-6?`
Subaxial spine
There are three regions of the cervical spine- which region is found at C7?
Transitional vertebrae
Briefly describe the atlas.
No body
No spinous processes
Large transverse processes
Transverse processes are penetrated by the foramen transversarium on each side in which the vertebral arteries pass through.
What name is given to the sticky out point of the axis?
Odontoid process/ dens or peg
What does C7 mark?
Cervicothoracic junction
What are the uncinate processes of the cervical spine?
Bony prominences which restrict lateral flexion
Where would you find the uncovertebral joints?
Between the uncinate processes and superior vertebrae
What do the uncovertebral joints serve as a surgical landmark for?
Placed closely to vulnerable vertebral artery
What happens to the width and height of the pedicles of the thoracic spine as you go down?
Height and width of thoracic pedicles increases
Which bones articulate with the thoracic vertebrae?
Ribs at costovertebral joint
Which section of the vertebrae has the biggest body?
Lumbar
What crosses the lateral zone of the sacrum laterally?
Sympathetic trunk
Lumbosacral trunk
Obturator nerve
Where would you find the anterior and posterior atlanto-occipital membranes?
Between C1 and corresponding parts of foramen magnum
The anterior atlanto-occipital membrane continues down as which ligament?
Anterior longitudal ligament
Which ligament is a very strong ligament and is important to look at when screening a patient with a spinal problem to ensure the ligament is in tact?
Transverse ligament
->the first lecture just goes into loads of detail about the anatomy of the spine, including ligaments and joints. I have stopped making flashcards on them as not sure if it’s a good use of our time but could be worth watching the lecture again to refresh the year one anatomy
What does spinal stability depend on in regards to the three-column theory?
At least two intact columns
->if there is a fracture in one part e.g. the anterior part, but the middle and posterior part are fine, spinal stability will be present
How many spinal nerves in each section of the spinal cord?
Cervical -8
Thoracic- 12
Lumbar- 5
Sacral- 5
Coccygeal- 1
->eight in cervical as first one arises superior to C1
Therefore, where would the C5 spinal nerve be?
Between C4 and 5
Which spinal nerve arises between C7 and T1?
C8 spinal nerve
