PELVIC SPUR Meaning and
Definition
-
A pelvic spur refers to a bony outgrowth or projection that is present in the pelvic region of certain mammals, particularly in the context of evolutionary biology. It is a naturally occurring, specialized anatomical feature that can commonly be found in some primates, such as humans. Typically, a pelvic spur refers specifically to a small, bony prominence that extends from the ilium bone of the pelvis.
The ilium is the largest of the three bones that make up the hip bone. This bony projection forms a distinctive spur-like structure that is situated towards the back and lower region of the pelvic bone. The pelvic spur serves as an attachment point for various muscles, ligaments, and tendons that play significant roles in providing stability and support to the pelvis.
In evolutionary terms, the presence of a pelvic spur is believed to be an adaptive response to promote efficient locomotion in certain mammalian species. It serves to enhance the strength and stability of the pelvis, allowing for greater support during weight-bearing activities such as walking, running, climbing, or other forms of movement. By providing a larger area for muscle attachment, the pelvic spur enables improved force transmission and enhances overall pelvic strength and functionality. The presence, size, and shape of pelvic spurs can vary across different species and can even differ between individuals within a species, presenting a fascinating aspect of biological diversity and adaptation.
Etymology of PELVIC SPUR
The term "pelvic spur" refers to a bony prominence or projection in the pelvic region, specifically in the area where the pubic bone joins the ilium. The etymology of this term can be broken down as follows:
1. Pelvic: The word "pelvic" is derived from the Latin word "pelvis", which means "basin" or "bucket". In anatomy, it is used to describe the area of the body bounded by the hip bones. It came into English from the Old French word "pelve" in the late 16th century.
2. Spur: The term "spur" comes from the Old English word "spura", which means "a sharp, pointed object". It is related to the Middle Dutch word "spore" and the Old High German word "sporo".
