Vertebral Column And Its Joints Flashcards
How many vertebrae are in each region of the vertebral column?
Possible exception?
7 cervical 12 thoracic 5 lumbar 5 sacral 4 coccyx
Can change the # in one region in expense to another; example: 4 lumbar and 6 sacral
~except 7 cervical is almost always a constant except in Klippel-Feil syndrome
Primary curvature vs. secondary curvature?
Primary: develops first in the embroyo; convex posteriorly; thoracic and sacral
Secondary: develops later; concave posteriorly; cervical and lumbar
What is another name for kyphosis?
What is kyphosis called in adolescents?
Dowagers Hump
Scheuermann’s disease
Two causes of scoliosis?
Myopathic (muscle disease)
hemivertebra (only have half of one vertebra)
Check notes app for Vetebra general features (answer on back of this card)
- Lamina
- Pedicle
- Vertebral foreamen
- Costal facet
- Superior and inferior costal facet
- superior articular facet
- vertebral arch
What two things make up one intervertebral foreamen?
A superior vertebral notch of an inferior vertebra and an inferior vertebral notch of a superior vertebra
Name two defining distinctions between cervical vertebrae (remember C1 and C2 are different; talking about C3-C7)
Bifid spinous process and cervical transverse processes have a hole in it (transverse foramen)
C1 is called?
Has no __ and __
What does it have that is unique? What is it for?
Atlas
No spinous process or vertebral body
Between anterior and posterior arch, theres a chunk of bone called the lateral mass; it has 2 articulate facets where you form the joint with the occipital bone (at the occipital condyles)
C2 (axis) has a spinous process and body. What does it have that’s unique ?
A vertical projection called the dens
Atlanta-occipital joint allows what movements?
Nodding yes, flexion, and extension
There are two Atlanto-axial joint subdivisions, what are they?
Atlanto-axial joint allows for what movement?
lateral and median
Rotation of head (no)
What is the most important ligament of the craniovertebral joints?
Location?
Transverse ligament of the axis
Medal surface of one lateral mass of atlas to other lateral mass
What is unique about C7 (vertebra prominens)
Long nonbifid spinous process
Transverse foramina are smaller and do not transmit vertebral artery
Why do thoracic vertebra have a lot of facets?
Costal facets of the vertebral body are called?
Transverse costal facet is located where?
Because they attach to the ribs
Demifacets (superior and inferior)
On the transverse process (thats why its not called demifacet because it is not located on the body)
How can you differentiate lumbar and thoracic vertebra?
What are transverse processes in the lumbar region called?
Where is mammillary process?
Spinous process on lumbar is shorter and wider
Costal processes
On posterior aspect of superior articular processes
