  1. Posture
    Homeostasis of systems where there is an ideal alignment for function pan-free movement
  2. What is needed for posture?
    • Stability (core strength/ joint structure)
    • Strength/tone of muscle
    • Proprioception/body awareness
    • Motor control
  3. Primary spinal curves
    • Thoracic
    • Sacral
  4. Innominate bone
    Formed from 3 distinct bones, which fuse together to form acetabulum
  5. Superior pelvic aperture/ pelvic inlet
    Sacral promontory, ala of sacrum, arcuate line, pectin pubis, pubic crest, pubic symphysis
  6. Normal motion of pelvis while standing
    • Tilted 50 deg
    • S1 articulated with L5
    • Optimal for movement
    • Aligns acetabulum for articulate ion with femur
  7. Pelvic floor
    • Covered with muscle
    • Structures move to anterior wall of true pelvis to relieve pressure of being pushed out by gravity and abdominal muscles
  8. Inferior pelvic aperture/ Pelvic outlet
    coccyx, sacrotuberous ligament , ischial tuberosity/ramis, inferior pubic ramis, public symphysis
  9. Specificities of male pelvis
    • smaller, heart shaped
    • ala oriented more vertically
    • infra pubic angle <70°
    • smaller sciatic notch
    • -----more susceptible to sciatic nerve compression bc less space and bigger muscles
    • sacrum more curved into pelvic space
    • bony land marks more defined
    • ischial spine more inferiorly and more rounded
  10. specificities of female pelvis
    • larger, wider
    • ala flare out
    • wider/ broader infrapubic angle (>90°)
    • -----ischial tuberosities further apart
    • ---------more stable while siting
    • wider/larger sciatic notch
    • sacrum a little bit flatter
    • smoother surfaces
    • ischial spines more medially and finer/”pointier”
    • -----attachment of sacrospinous ligament
    • obturator foramen different shape
  11. what structures convert lesser and greater sciatic notch into foramen?
    Sacrotuberous and sacrospinous ligaments
  12. Pudendal nerve
    exit pelvis through great sciatic foreman, raps around ischial spine, re-enters pelvis through lesser sciatic foramen, innervates pelvic visceral and pelvic floor muscles
  13. greater/ false pelvis
    • superior aperture to imaginary line across iliac crest
    • contains abdominal viscera
    • in confines of ala of pubis
  14. lesser/true pelvis
    • space btwn pelvis inlet and outlet
    • where true pelvis viscera is
