The Spine & Hip Joint Flashcards
Is sacrum considered part of the spine or pelvic girdle?
spine
Using bony landmarks, what are 2 different ways of describing ideal alignment in tadasana?
- pubic bone + tail bone parallel to floor
2. ASIS joints + pubic bone parallel to wall in front
Is hip joint made for mobility or stability? Why?
Stability bc femur has 70% contact with acetabulum
What is meant by “hip joint”? Where is it located on the body?
- It is the ball-and-socket joint where the femur goes into the acetabulum
- It is located at the top of the leg near the pubic bone
In what planes of space does movement at the hip occur? Why?
- All 3 planes bc it is a ball-and-socket joint
Why is it important to always keep a bit of softness behind the skin of the inner groin when the hip joint is in extension?
- To avoid stressing the ligaments at the front of the hip
Where are the quads located and what is their primary action(s)?
Located in front of the thigh and they are used to flex the hip joint
Where are the hamstrings located and what is their primary action(s)?
Located at back of the thigh and allow for extension of the knee joint
Describe 4 curves of the spine. Name, direction of curve, how many vertebrae?
Cervical, secondary curve, 7 bones
Thoracic, primary curve, 12 bones
Lumbar, secondary curve, 5 bones
Sacrum, primary curve, 5-8 bones but can vary
List 3 functions of the vertebral column?
- Support trunk
- Enclose spinal cord
- Provide site for muscle attachment
What does the shape of the vertebra tell us about the idea of having a straight spine?
- When aligned correctly, the wedge shape of the vertebrae creates curves in the spine when aligned so the idea of a straight spine cannot happen when there is correct alignment.
What is the overall shape of the spinal column?
From the back: it looks like an elongated pyramid
From the side: it looks like an S
In general, what regions of the vertebral column have more freedom?
Cervical, lumbar regions
In what region of the spine is rotation not possible?
- Lumbar bc the shape of the vertebrae prevents it
In what region of the spine is hyperextension not possible and why?
- Thoracic spine bc of the shape of the vertebrae
In which action do the cervical and lumbar regions of the spine need most care and attention, flexion or extension?
- Flexion
What can the lumbar spine tell you about someone’s habitual standing pattern?
- Depending on if the spine is lordodic, you can see if there is gripping in the front or back body
Which group of back muscles are made for stabilization: the deep smaller muscles or the more superficial large muscles.
- Deep smaller muscles
What is a great way to stretch and strengthen the intercostal muscles?
- Pranayama
Why is it important to teach with organizational goals rather than range of motion goals?
Organizational goals help prevent injury while exercising/stretching muscles correctly. If you teach with range of motion goals, people may sacrifice their correct body organization which can lead to injury.
