Term
| The vertabrae are held together by what? |
|
Definition
Ligaments
Intervertebral discs
Synovial joints between the articular process |
|
|
Term
| In the thoracic vertebra, has what purpose? |
|
Definition
| It is weight bearing and contains red bone marrow |
|
|
Term
| What does the basivertebral veins do? |
|
Definition
|
|
Term
| Why does the nueral arch and the processes exist? |
|
Definition
For the protection of the spinal cord
For attatchment of muscles
For articulation with ribs (long transverse processes)
and for regulation of movements |
|
|
Term
| What forms synovial joints? |
|
Definition
| Superior and inferior articular facets |
|
|
Term
| Why are the spinous processes downturned? |
|
Definition
| To overlap the inferior one. |
|
|
Term
| Give characteristics of cervical vertebra |
|
Definition
Has a smaller body which carries less weight and overlaps the lower vertebra anteriorly
Has a bifid spinous process |
|
|
Term
| Do all vertebra have costal elements or just thoracic vertebra? |
|
Definition
| They all do. However, in cervical, lumber and sacral regions they are incorporated into the vertabrae. Thus, in cervical vertebrae, the posterior tubercle is the true transverse process and the anterior tubercle is the costal element |
|
|
Term
| Give characteristics ofthe lumbar vertebra |
|
Definition
They are the most massive vertebrae, with increasing body size inferiorly
The lumbar spines are massive and project posteriorly. |
|
|
Term
| Why are you able to perform and lumbar puncture? |
|
Definition
| Because the lumbar spines do not overlap |
|
|
Term
| How many vertebrae is the sacrum made up of? |
|
Definition
| The sacram is 5 vertebrae fused into one. |
|
|
Term
| What forms the intervertebral discs? |
|
Definition
| A layer of hyaline cartilage and fibrocartilage |
|
|
Term
| Differences in height between the beginning and end of the day are a result of what? |
|
Definition
| The intervertebral discs being compressed by the weight of the body |
|
|
Term
| Why is there no ligament between the pedicles of the spine? |
|
Definition
| Because of the intervertebral foramina and the emergence of spinal nerves |
|
|
Term
| What is the purpose of the cervical flexure of the spine? |
|
Definition
|
|
Term
| What is the purpose of the lumbar flexure? |
|
Definition
| To support the trunk for standing and walking |
|
|
Term
| What is the original fetal curve? |
|
Definition
|
|
Term
| What are the movements of the vertebral column? |
|
Definition
| Anterior flexion, extension, lateral flexion, and lateral rotation |
|
|
Term
| Where is a lumbar puncture performed? |
|
Definition
|
|
Term
| What is the final destination for a lumbar puncture? |
|
Definition
|
|
Term
| What is the function of the intermediate back muscles? |
|
Definition
| Has respiratory functions. They elongate the thoracic cavity and are thus muscles of inspiration. |
|
|
Term
| What is the purpose of the deep back muscles? |
|
Definition
They are intrinisic muscles of the back. When acting jointly, they extend the vertebral joints (they prevent/regulate flexion at these joints).
Unilaterally, they laterally bend and rotate the spinal column |
|
|
Term
| What do the erector spinae do? |
|
Definition
| Fill the grooves between the spines of the vertebrae, the transverse processes and the ribs |
|
|
Term
| The erector spinae muscles start where? |
|
Definition
| They start at the sacral region, enlarge and are powerful in the lumbar region |
|
|
Term
| The erector spinae, what does the depth of the muscle tell you about its size? |
|
Definition
| The longest bundle is most superficial and the shortest is deep in contact with bone |
|
