For the muscle of the hand, see Opposite of the little finger (hand)
The opponent of the little toe of the foot is a muscle located in the foot, under the short flexor muscle of the fifth finger, with which it is often confused.
The opposing muscle of the V finger is located deep into the short flexor of the V finger. It is fickle. Its posterior insertions are common with those of the short flexor (in the sheath of the long peroneus, at the level of the cuboid, at the posterior end of the metatarsal V), but it is separated therefrom, after a variable path, to insert into the two anterior thirds of the diaphysis of the metatarsal V. It shares the relationships of the short flexor, located more superficially. Like the short flexor of the fifth finger, it is innervated by a branch from the lateral plantar nerve.
Its action is the same as the short flexor of the small finger, flexing the small finger. It also has an atrophied function that is what gives it its name, ie, oppose the finger, which is impossible on the human foot and is reminiscent of the hominid inheritance of our species.
