Gemelli muscles
Gemelli Muscles
Gemelli muscles (pronunciation: jeh-MEL-ee) are a pair of small muscles in the human body that are part of the rotator cuff of the hip. The term "gemelli" is derived from the Latin word for "twins", reflecting the fact that there are two of these muscles, one superior and one inferior.
Etymology
The term "gemelli" is derived from the Latin "geminus", meaning "twin". This reflects the fact that there are two of these muscles, one superior and one inferior. The term "muscle" comes from the Latin "musculus", meaning "little mouse", which is a reference to the appearance and movement of certain muscles.
Function
The gemelli muscles, along with the obturator internus muscle, form the triceps coxae. This group of muscles primarily functions to laterally rotate the hip joint. Additionally, when the hip is flexed, these muscles can also adduct the thigh.
