Anatomy (Vertebral Column) Flashcards
1
Q
A
Axis (C2)
2
Q
10 vs 20 Curvatures
A
Primary - ) born with it & called kyphosis
Secondary - ( develops after birth & called lordosis

Q
Weight Bearing Function of Discs
A
- Central nucleus pulposus can be compresses out and provides cushion
5
Q
Vertebral Colmun Functions (4)
A
- Protect spinla cord and nerves
- Supports the weight of the body
- Provides a partially rigid and flexible axis for the body
- Important role in posture and locomotion
6
Q
Unstable Spinal Fracture (4)
A
- “Serious”
- Really hard to carry/distribute weight
- Can progress and cause further neurological damage
- Can cause spinal deformity
7
Q
Other Names for Anterior Longitudinal Ligament
A
- Instead of “longitudinal” it’s called atlantoaxial between C1-C2 and atlantooccipital between C1 and occipital bone
8
Q
Intervertebral Disc
A
- Cartilaginous Joint
- Seperates vertebral bodies
- Key to stability
9
Q
Action of Paradox
A
- Epaxial muscles allow trunk flexion by gradual relaxation during flexion of anterior muscles
- Bicep relaxes slowly to allow arm to extend down
- Lets gravity do most of the work
10
Q
A
Atlas (C1)
11
Q
Zygapophyseal (facet) Joint
A
- Synovial joint
- Between superior and inferior articulating processes
- Allow some movement
12
Q
Movement of Vertebral Column
A
- The small amount of movemntn around each disc is amplified by summation so that large amount of flexibility extends entire vertebral column
13
Q
Other Names for Posterior Longitudinal Ligament
A
- Renamed “tectorial ligament” at & above C2
14
Q
Nucleus Pulosus
A
- Gel-like/watery substance that cusions movement
- Center of intervertebral discs
- Discs can compress by letting this out after being upright for a while
15
Q
Stable Spinal Fracture (4)
A
- “Minor”
- No neurological problems
- Can still support weight, but not perfectly
- Vertbral column is still protecting nervous system
