What are the forearm muscles called that straighten the wrist, hand, and fingers?

The forearm muscles that are responsible for straightening the wrist, hand, and fingers are known as extensors. These muscles play a crucial role in extending the digits and the wrist, allowing for movements such as raising the hand or grasping objects. When these muscles contract, they pull on the tendons linked to the bones in the hand and fingers, facilitating extension.

The forearm contains a variety of muscle groups, and the extensors are specifically located on the posterior aspect of the forearm. Their function contrasts with that of the flexors, which are responsible for bending the wrist and fingers. Understanding the roles of these muscle groups is fundamental for anyone studying the anatomy and physiology relevant to esthetics, as it relates to various treatments and therapeutic techniques that involve the use of the hands.
