HIP BONE (COXAL BONE) Definition The hip bone is a large, irregular bone that forms the side of the pelvis. Each person has two hip bones – one on the right and one on the left. Parts of the Hip Bone: - Each hip bone is formed by the fusion of three bones: Ilium – upper, broad, fan-shaped part Ischium – lower, posterior part Pubis – lower, anterior part These three meet at a deep cup-shaped cavity called the acetabulum. Important Features Acetabulum – socket for the head of the femur (hip joint) Iliac crest – upper curved margin of the ilium Ischial tuberosity – sitting bone Pubic symphysis – joint between two pubic bones PELVIS Definition The pelvis is a bony ring formed by: Two hip bones One sacrum One coccyx Functions of the Pelvis Supports body weight Transfers weight to lower limbs Protects pelvic organs Urinary bladder Rectum Reproductive organs Helps in walking and posture TYPES OF PELVIS 1. Male Pelvis Narrow and deep Heart-shaped pelvic inlet Less spacious 2. Female Pelvis Broad and shallow Oval pelvic inlet More spacious (important for childbirth) HIP JOINT Type: Ball and socket joint Formed between: Head of femur Acetabulum of the hip bone Allows: Flexion Extension Rotation Abduction & adduction
