Etymology

Origin of pelvis

1605–15; < New Latin; Latin: basin; akin to Greek pellís bowl

Explanation

Your pelvis is the series of bones at the base of the spine that support your legs. Remember that Elvis had a knack for moving his pelvis, and then you may more easily remember this body part! In humans, hip bones make up either side of the pelvis, with the sacrum and coccyx bones at the back. This bony pelvis makes it possible for us to walk upright with jointed legs, and it also forms a protective case for the internal organs that sit low in the body. In Latin, pelvis means "basin," from the Greek pelike, "goblet or bowl."
