Summary Introduction
To review:
The relationship between the muscles that flex and extend the wrist and their location in the body.
Introduction:
The skeletal muscles of the hand involved in the movement of the wrist and the fingers are named based on their function. The muscles that help in flexing the wrist are named flexor muscles, whereas the ones that help in the extension of the wrist are known as extensor muscles.
