  • Pelvic Girdle
    Connects the legs to the body's core, consisting of the right and left coxal bones.
  • Coxal Bone
    Also known as os coxae, it is formed by the fusion of the ilium, ischium, and pubis.
  • Ilium
    The superior, flattish region of the coxal bone, featuring the prominent iliac crest.
  • Iliac Crest
    A prominent ridge on the ilium, serving as an attachment point for muscles.
  • Ischium
    Forms the lower posterior region of the pelvis, known as the 'sit bones'.
  • Pubis
    The lower anterior region of the coxal bone, meeting at the pubic symphysis.
  • Pubic Symphysis
    A cartilaginous joint where the two pubic bones meet in the front.
  • Acetabulum
    A deep socket in the coxal bone where the femur joins, forming the hip joint.

  • Pelvic Inlet
    The upper opening of the pelvis, heart-shaped in males and oval in females.
  • Pubic Arch
    The angle formed by the coxal bones at the pubic symphysis, wider in females.
  • Obturator Foramen
    A large opening in the coxal bone, allowing passage of nerves and blood vessels.
