Pronunciation: [pjˈuːbɪk bˈə͡ʊn] (IPA) 
The pubic bone is an important part of the human skeletal system, located in the pelvic region. It is often misspelled as "public bone," but the correct spelling is "pubic bone." The "b" sound in this word is pronounced as a voiced bilabial plosive, represented in IPA phonetic transcription as /b/. The correct spelling of this word is important in medical contexts to accurately communicate information about the human body.
The pubic bone, also known as the pubis or pubis bone, is a part of the pelvic girdle located in the lower part of the abdomen. It is a flat, triangular-shaped bone made up of dense, hard tissue that forms the anterior portion of the coxal bone.
The pubic bone has two main components – the superior ramus and the inferior ramus. The superior ramus extends upwards from the body of the pubis bone towards the ilium, while the inferior ramus projects downward to meet the ischium bone. These two sides join at a joint called the pubic symphysis, which is a fibrous cartilage joint that allows a slight amount of movement and flexibility.
The pubic bone serves as an attachment point for various muscles, tendons, and ligaments in the pelvis. It provides support for the pelvic organs, including the bladder and reproductive organs. Additionally, it acts as a protective barrier for these organs.
During childbirth, the pubic bone plays a crucial role by providing stability and support for the mother's body. The wide surface area of the pubic bone helps distribute the pressure and weight during labor, allowing for a smoother and safer passage of the baby through the birth canal.
In summary, the pubic bone is a sturdy triangular bone forming part of the pelvic girdle. It serves as an attachment point for muscles and ligaments, supports pelvic organs, and plays a pivotal role in childbirth, providing stability and facilitating safe delivery.

The word "pubic" is derived from the Latin term "pubes", which originally referred to the hair in the genital area during puberty. The word "bone" comes from the Old English word "ban", which means "bone" or "hard part of the body". Therefore, the term "pubic bone" refers to the bony structure located in the pelvic region, specifically the front part of the pelvis.
