Which muscle group is involved in the extension of the fingers?

The group of muscles responsible for the extension of the fingers is identified as the extensors. These muscles are located primarily in the forearm and are responsible for straightening the fingers by extending the joints. When the extensors contract, they pull on the tendons that run down to the fingers, allowing for a range of motions essential for various hand functions, including gripping and releasing objects.

In contrast, flexors are the muscles that enable the bending of the fingers, while abductors and adductors pertain to movements that involve spreading the fingers apart or bringing them together, respectively. Thus, the correct identification of extensors highlights their crucial role in finger movements, differentiating them from the functions of the other muscle groups listed.
