Question | Answer |
What are the function of the spinal column? | -provides body posture, support, muscle attachment -protect the cord |
How many vertebrae total? | 31-33 total |
Cervical | C1-C7 |
Thoracic | T1-T12 |
Lumbar | L1-L5 |
Sacral | S1-S5 |
Coccygeal | 2-4 |
What are the three types of vertebrae? | Cervical, Thoracic, Lumbar |
What is Annulus Fibrosis? | Harder outside |
What is Nucleus pulposus? | Softer inside |
What is the function of the Intervetebral foramen? | |
What is Disk herniation? | Protrusion of nucleus pulposus through annulus fibrosus |
What is Lordosis? | Excessive anterior curvature of lumbar spine |
What is Kyphosis? | Excessive posterior curvature of thoracic spine |
What is Scoliosis ? | excessive lateral curvature (most common) |
What is Atlas? | C1- superior articulating facets with occipital condyles of skull |
What is Axis? | C2- articulates with C1. Dens or odontoid process of C2 projects up into area where body of C1 would be |
What is another name for the Atlas? | Atlanto-occipital Joint |
What is another name for the Axis? | Atlanto-axial joint |
Where are Zygapophyseal Joints | Between superior and inferior facet joints |
What is the function of Zygapophyseal joint? | Prevent excessive torsion |
What do disks serve as? | -spacers to allow nerve roots to exit spinal canal -act as shock absobers |
Atlanto-occipital membrane | Attach occipital bone of skull to C1 |
Atlanto-axial membrane | Connects C1 to C2 |
Transverse (Hangman's) ligament | Connects lateral masses on C1 and holds dens in place |
Anterior longitudinal ligament | limits hyper-extension |
Posterior longitudinal ligament | limits flexion |
Ligamentum flavum | -Limits lateral flexion - Runs between laminae |
Interspinous | -Between spinous processes -Limits flexion |
Supraspinous | -Between spinous processes -Limits flexion |
Ligamentum Nuchae | -Helps to supports cervical curve -Place for muscle attachment |
what is C1 involved in? | Flexion only |
What is C2 involved in? | Rotation only |
Are ribs 8-12 "floating ribs"? | No, only 11-12 are floating ribs. 8-10 are false ribs |
What are the 3 joints in anterior articulations of the thorax comprised of? | -Chondrosternal -Costochondal -Interchodral |
What are the four muscles associated with cervical flexion? | Sternocleidomastoid, longus colli, longus capitis, and scaleni |
T/F Two muscles associated with trunk and pelvic rotation are internal oblique (bilateral) and external oblique (contralateral) | False |
T/F Atlanto- axial joint allows rotation C1 on top of C2 | True |
T/F Lordosis is anterior curvature on the lumbar spine; while Kyphosis is anterior curvature of thoracic spine | False, Kyphosis is posterior curvature |
T/F inhalation process can be described when the diaphragm contracting and creating more space in thoracic capacity. | True |
What are Chondrosternal joints? (anterior attachment) | Tied by Costosternal ligament |
What are Costochondral joints? (anterior attachment) | Permit little movement |
What are Interchondral joints? (anterior attachment) | Interchondral ligament |
What is Corpocapitate articulation? (Posterior attachment) | -Between vertebral body and rib head -Stabilized by superior costotransverse and costovertebral radiate ligaments |
What is Costotransverse articulation? (Posterior attachment) | -Between tubercles of ribs 1-10 and transverse processes -Stabilized by the costotransverse ligament, ligament of the neck, and ligament of the tubercle |
What is the mechanics of respiration? | -Enlarge thoracic capacity -Creates vacuum -Air moves into lungs to equalize pressure |
Quiet inspiration | -diaghragm in charge. Some assistance from scalenes and intercostal muscles. |
Quiet expiration | no direct muscle action. Elastic recoil of lungs sufficient |
Deep inspiration and expiration | recruits more muscles |
What does Phrenic nerve damage typically result in? | paralysis of half of the diaphragm |
