Axial Skeleton AKR Flashcards
How many pairs of ribs does the human body have?
12
What are the 7 spinal column motions?
Flexion/extension/hyperextension
Lateral flexion to the R/L
Rotation to the R/L
Circumduction
If the primary motion of the pelvis is anterior rotation, what is the secondary motion of the lumbar spine?
Extension
If the primary motion of the pelvis is posterior rotation, what is the secondary motion of the lumbar spine?
Flexion
If the primary motion of the pelvis is right lateral rotation, what is the secondary motion of the lumbar spine?
Right lateral flexion
If the primary motion of the pelvis is left lateral rotation, what is the secondary motion of the lumbar spine?
Left lateral flexion
If the primary motion of the pelvis is right transverse rotation, what is the secondary motion of the lumbar spine?
Left lateral rotation
If the primary motion of the pelvis is left transverse rotation, what is the secondary motion of the lumbar spine?
Right lateral rotation
How is the spine positioned in anatomical position?
Extended in sagittal
Neutral in frontal/transverse

What does bio and mechanics mean?
Bio= living systems
Mechanics= study of motion and the effect of forces on objects
Biomechanics= the study of motion and the effect of forces on living systems
What are the 2 reasons to study biomechanics?
- Improve performance/quality of life
- Prevent injuries/improve rehab
What are the 6 multidisciplinary subjects in biomechanics
“MAPP-EM”
Motor control
Anatomy
Physics
Physiology
Engineering
Math
What are the 3 types of joints/how much they move
Synarthrosis- immoveable
Amphiarthrosis- slightly moveable
Synovial- freely moveable
What are the 6 synovial joint types and their degrees of freedom
- Hinge- 1 DOF
- Pivot- 1 DOF
- Condyloid- 2 DOF
- Saddle- 2 DOF
- Gliding- 2 DOF
- Ball and socket- 3 DOF
