Coxae bones Ilium, Ischium, Pubis, Acetabulum

1
Coxae bones(Ilium, Ischium, Pubis, Acetabulum)
2
Ilium

• Ilium means flank
• The largest area of the hip bones
• Forms the superior region of the coxal
• Consists of 2 large plates that help to support
  the internal organs and provide attachment for
  muscles of the back, sides, and the buttocks
• The hip joint of the femur is part of the ilium

3
Ischium

• It attaches to the gluteal loin
• This is the bone we sit on
• It consists of 2 broad curves
• Lies below the ilium
• It is attached to the pubis in the front and the
  ilium in the back
• It functions as a place for muscle attachment
  which provides support and protection

4
Pubis Bone

• It is the located at the ventral and anterior
  side (front-most portion of the coxae bone.
• It attaches to the ilium and on the sides of the
  ischium on the bottom
• It provides structural support as well as
  allowing for muscles to attach to the inner thigh
• It is covered by a layer of fat (that is covered
  by mons pubis) which protects the pubic bone
• The left and right hip bones join at the Pubic
  symphasis

5
Acetabulum

• Part of the ball and socket joint
• The hip joint is a joint between the acetabulum
  and the femar
• Its very deep which allows for more stability,
  but less flexibility
• Its function is to support the weight of the
  body
• This area would similar to a condyle because it
  is rounded, smoother, and more articular
• The smoothness allows there to be less friction
  and irritation with movement
