Which flexor muscle connects to the radius?

The flexor muscles that connect to the radius include both the flexor digitorum superficialis and the flexor pollicis longus. The flexor digitorum superficialis originates from the medial epicondyle of the humerus and the radius and is responsible for flexing the middle phalanges of the fingers. The flexor pollicis longus also originates from the radius and serves to flex the thumb.

Choosing both of these muscles highlights their respective roles in flexing the fingers and thumb while being anatomically connected to the radius. This distinction is essential for understanding how these muscles contribute to movements in the forearm and hand. While other muscles, such as the flexor carpi ulnaris, are important for wrist flexion, they do not attach to the radius and therefore do not connect to the radius like the selected muscles do. Therefore, recognizing the connection of these muscles to the radius is important for a comprehensive understanding of the muscle anatomy in this area.
