伸肌, 伸展肌肉
a muscle that helps a body part or limb be stretched out by contraction
The extensor refers to a group of muscles responsible for extending or straightening various joints in the body. These muscles work in opposition to flexor muscles, which are responsible for bending or flexing joints. Extensor muscles are found throughout the body, such as the extensor muscles in the forearm that straighten the fingers or the extensor muscles in the leg that help in extending the knee joint. The extensor muscles play a vital role in maintaining posture, generating force for movements, and providing stability to joints. Their coordinated action allows for efficient movement and function in everyday activities and athletic endeavors.
