Verified step by step guidance
1
Understand the components of the pelvic girdle: The pelvic girdle is primarily composed of the os coxae, which is made up of three bones: the ilium, the pubis, and the ischium.
Identify the bones listed in the problem: os coxae, ilium, pubis, ischium, and femur.
Recognize that the os coxae is a collective term for the ilium, pubis, and ischium, which are all part of the pelvic girdle.
Consider the femur: The femur is the thigh bone and is not part of the pelvic girdle. It articulates with the pelvic girdle at the hip joint but is not a component of it.
Conclude that the femur is the bone that is not part of the pelvic girdle, as it is distinct from the os coxae and its components (ilium, pubis, ischium).
