|
Spinal nerves C1-C7 emerge.. |
Above their corresponding vertebrae |
|
Spinal nerves emergr |
Below corresponding vertebrae |
|
General functions of spinal column |
Carriage and protection of spinal cord and nerves Support to thoracic and rib cage Transfers weight of upper limb to lower limb Absorbs shock Provides attachment for muscle |
|
Purpose of the articulate facets |
To interlock and reduce individual movement of vertebra |
|
C1 Atlas carries... |
The weight of the cranium |
|
Atlas does not have |
A body. |
|
C2 is also known as the |
Axis |
|
The odontoid process of the axis forms a |
Pivot joint with atlas |
|
The strength of the transverse ligament is required to |
Prevent the odontoid process from impacting against the medulla and causing death |
|
Cervical vertebra have... |
Small bodies and holes in their transverse processes |
|
The most prominent vertebrae in the neck is |
C7, vertebra prominens |
|
The vertebral foramen is large in the cervical vertebra due to |
The large size of the spinal cord at this level |
|
The vertebral artery only travels through the |
Upper 6 Vertebra, not C7. |
|
The vertebral artery can get compressed within the |
Foramen transversarium |
|
The thoracic vertebrae... |
Increase in size and have articulate facets for ribs |
|
The thoracic vertebrae have a |
Heart shaped body |
|
The lumbar vertebra... |
Cope with large forces and articulations are aligned to prevent rotational movement. |
|
The body of the lumbar vertebra |
Are large and kidney shaped |
|
The foramen of the lumbar vertebrae are |
Small due to the decrease in size of the spinal cord. |
|
The sacrum consists of |
5 fused vertebrae |
|
The sacrum transmits weight to the |
Pelvic girdle |
|
The last parts of the spinal nerve come through an opening at the base of the sacrum called |
The sacral hiatus |
|
The sacral hiatus is used for |
Sacral epidural |
|
Intervertebral discs |
Resist compression and form a mobile joint. |
|
Intervertebral discs are classed as |
Secondary cartilagenous joints |
|
The intervertebral discs are present from |
Beneath C2 to above S1 |
|
The intervertebral discs increase in thickness |
Distally |
|
What is the remnant of the notochord? |
The nucleus pulposus |
|
Zygapophyseal joints are located |
Between articulate facets of adjacent vertebra |
|
Zygapophyseal joints are classed as |
Simple synovial plane joints |
|
The ligamentum flavum is |
An elastic ligament joining adjacent vertebra |
|
The ligamentum nuchae can be palpated |
In the neck |
|
Ligament above the vertebra |
Supraspinous ligament |
|
Ligament below the vertebra |
Interspinous ligament |
|
Force applied to the vertebral column will increase the pressure of |
The nucleus pulposus |
|
The increase in NP pressure will tense the |
Annulus fibrosus |
|
IV disc herniation is.. |
The rupture of the NP through the AF |
|
Spinal curvature anteriorly |
Lordosis |
|
Spinal curvature posteriorly |
Kyphosis |
|
Curvature of the spine is related to |
Disc shape |
|
The fetus is in a postural state known as |
Universal flexion |
|
Pregnant women have lumbar |
Hyperlordosis |
|
Spondylolysis |
Fracture in region of articular facets (no displacement) Cause of lower back pain |
|
Spondy |
Spinet |
