Which of the following bones is not part of the pelvic girdle?

• A. Ischium
• B. Pubis
• C. Coccyx
• D. Scapula

Answer: (D)

The scapula is the correct choice as it is not part of the pelvic girdle. The pelvic girdle is formed by the hip bones, which consist of the ilium, ischium, and pubis. These three bones come together to form the acetabulum, which is the socket for the hip joint. The coccyx, while it is located at the base of the vertebral column, is also considered part of the pelvic region but is not classified as part of the pelvic girdle itself, which is specifically related to the hip bones. In contrast, the scapula, commonly known as the shoulder blade, belongs to the shoulder girdle and serves to connect the arm to the trunk. This anatomical detail confirms that the scapula is not associated with the structures that comprise the pelvic girdle, making it the correct answer to the question.
