Flexor digiti minimi brevis - ...

Muscle parts


Latin name

Musculus flexor digiti minimi brevis (manus)

Latin muscle parts



Hand muscle – hypothenar group


In English this muscle’s name is the short muscle that bends the little finger. The word flexor comes from the Latin flectere meaning “to bend.” 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. Brevis is the Latin term meaning “short.” This is being used as a comparative reference to a longer muscle that does the same thing.
