Correct spelling for the English word "pubic spine" is [pjˈuːbɪk spˈa͡ɪn], [pjˈuːbɪk spˈaɪn], [p_j_ˈuː_b_ɪ_k s_p_ˈaɪ_n] (IPA phonetic alphabet).
The pubic spine is a bony structure located in the lower part of the pelvis, specifically in the area known as the pubic symphysis. It is also referred to as the pubic eminence or the pubic crest. The pubic spine serves as a significant landmark and is essential in understanding the anatomy of the pelvis.
The pubic spine is a curved and elevated ridge of bone that runs horizontally along the anterior (front) aspect of the pelvis. It is formed by the fusion of the two pubic bones, which meet in the midline at the symphysis pubis. The joining of these bones is stabilized by fibrocartilaginous tissue and ligaments.
The pubic spine has several important attachments, including muscles, tendons, and ligaments. These structures play a vital role in stabilizing the pelvis and facilitating various movements and activities related to the lower limb.
In clinical practice, the pubic spine is important in identifying anatomical landmarks during imaging studies, such as X-rays or CT scans. It is also a reference point during surgical procedures involving the pelvis, providing guidance in the placement of implants or the identification of specific structures.
In summary, the pubic spine is a bony ridge located in the lower pelvis, serving as a significant landmark in the anatomy of the pubic symphysis. Its fusion forms the symphysis pubis and plays a crucial role in stabilizing the pelvis.

The word "pubic spine" does not have a direct etymology of its own as it is a compound term composed of two separate elements: "pubic" and "spine".
The term "pubic" refers to the pubic bone, which is part of the pelvis. It stems from the Latin word "pubes" meaning "pubic hair", which eventually came to include the region encompassing the hair, the bone, and the related structures.
On the other hand, "spine" has its roots in the Latin word "spina", which means "thorn" or "spine". It refers to the series of individual bones called vertebrae that form a flexible column protecting the spinal cord.
Therefore, when combined, "pubic spine" refers to the bony prominence located on the pubic bone, which is also known as the pubic tubercle or pubic crest.
