Extensor digiti minimi muscle

Definition

The tendon of insertion is sometimes divided and gives a slip to the fourth digit. An ulnar slip has been observed to end on the base of the fifth metacarpal, thus exactly reproducing the arrangement of the serially homologous slip known as peroneus tertius in the leg. The muscle may be absent in rare cases, but fusion with extensor digitorum is frequent, in which case the tendon comes from the common extensor.

The Extensor digiti minimi muscle is a part of the Muscular.
