Contraction of the muscle that is attached to the radial tuberosity results in

Bending or flexion of the forearm and elbow

Radial tuberosity, alongside head and neck, is one of the important landmarks of the radius. It is a bony projection on the middle side of the radius where the tendons of the biceps branchii muscle insert itself.

In Anatomy, Radial tuberosity can be found at the center right of the left elbow and the upper left of the left forearm when the palm is facing upward.
