Bones of the pelvic girdle

• The bones of the pelvic girdle is formed by and composed of

  Two coxal bones and 3 pairs of fused bones (Ilium, Ischium and Pubis)
• Pelvic girdle


  two coxal bones, sacrum
• Pelvis


  two coxal bones, sacrum, coccyx
• What part of the body rest upon the pelvis?

  Upper body
• Pelvis protects several organs

  Reproductive organs, urinary bladder, and part of the large intestine
• Coxal bone(def)


  hip bone
• Ilium of coxal bone

  
• Pubis of coxal bone

  
• Ischium of coxal bone

  
• Pubic arch

  
• iliac crest of ilium

  
• Sacroiliac joint

  
• Pelvic brim

  
• Ischial spine

  
• Pubic symphysis

  
• Posterior Superior Iliac Spine (PSIS)

  
• posterior inferior iliac spine (PIIS)

  
• Greater sciatic notch of ilium

  
• Ischial body of ischium

  
• Ischial tuberosity of ischium

  
• Ischial ramus of ischium

  
• Anterior superior iliac spine (ASIS)

  
• Anterior inferior iliac spine (AIIS)

  
• Body of pubis

  
• Inferior pubic ramus

  
• Oburator foramen

  
• The female's pelvis


  Inlet is larger and more circular

  Shallower, on the whole, and the bones are lighter and thinner

  Ilia flare more laterally

  Sacrum is shorter and less curved

  Ischial spines are shorter and farther apart; thus, the outlet is larger

  Pubic arch is more rounded because the angle of the pubic arch is greater

  
• male pelvis vs female pelvis

  Male = narrow (greater propensity for location and elevation)

  Female = wider

  *Difference in which width of sacrum
