Pronunciation: [hˈɪp bˈə͡ʊn] (IPA) 
The word "hip bone" is spelled as /hɪp/ and /boʊn/. The first part of the word "hip" is pronounced as "h" followed by a short "i" sound, "p" sound, and ends with a puff of air. The second part "bone" is pronounced as "b" sound followed by a long "o" sound, and ends with a nasal "n" sound. These sounds are combined to form the word "hip bone", which refers to the large bone located in the pelvic region.
The hip bone, also known as the coxal bone or innominate bone, is a large and sturdy flat bone located in the pelvic region of the human body. It is an essential component of the pelvic girdle and forms a crucial connection between the axial skeleton (spine) and the lower limbs.
The hip bone is comprised of three main parts: the ilium, the ischium, and the pubis. Each of these parts contributes to the formation of the acetabulum, which is a socket-like structure that interacts with the head of the femur to form the hip joint. The ilium is the largest and uppermost portion of the hip bone, providing support to the abdomen and helping to maintain the overall structure and balance of the body. The ischium forms the lower and back part of the hip bone, while the pubis is the front portion.
Together, these three sections combine to create a strong and robust bone structure that plays a vital role in providing stability, weight-bearing capabilities, and protection to the pelvic organs. The hip bone also serves as an attachment site for various muscles responsible for movements such as walking, running, and standing. Overall, the hip bone is integral to the proper functioning and structural integrity of the human body, enabling mobility and providing a solid foundation for the lower extremities.
The word "hip bone" is derived from the Old English term "hype" or "heope", which originally referred to the projecting part on each side of the body formed by the upper part of the thigh bone's head. This term goes back to the Proto-Germanic root "haupaz", meaning "head". Over time, it evolved into "hiup" or "hiupe" in Middle English before eventually becoming "hip" in Modern English. The addition of "bone" simply indicates that it refers to a specific bone in the body.
