Latin name

Musculus abductor digiti minimi (manus)

Latin muscle parts



Hand muscle – hypothenar group


In English, this muscle’s name is the muscle that leads the smallest finger away (from the other fingers). Abductor is a term that describes the function or action of the muscle. It literally means to draw or to lead away from and is derived from the Latin ab meaning “away from” and ducere meaning “to lead or to draw.” The term digiti is from the Latin digitus, which originally meant the “pointing thing,” a term that is similar to the Sanskrit word “dic” meaning to show or point out. Because we point with our fingers the term was applied to the fingers and then the toes. The term minimus is Latin for “least or smallest.” Its use in this instance is in reference to the fact that the muscle attaches to the smallest finger of the hand.
