Ulna and Radius Bones and Muscles

The Radius and Ulna bones are connected between the elbow joint and the wrist. The radius is connected to the thumb side of the wrist. It's also on the outside or lateral side of the elbow. The radius is bigger and longer than the Ulna

DESCRIPTION: Long bone, prism like shapes, and slightly curved longitudinally.

The Ulna is on the inside, or the medial side, of the forearm closet to the body. The bony part of the arm which some people think as the elbow is the tip of the Ulna.

STRUCTURE: The long narrow medulla cavity of the Ulna is enclosed in a strong wall of cortical tissue which is thickest along the intercourse border and dorsal surface.

Both Radius and the Ulna are connect the humorous bone of the upper arm the elbow joint. The elbow provides rotation of the lower arm through twisting of the Radius and Ulna. Normally the Radius and Ulna are parallel to each other but during pro nation (the rotation of the lower arm) the radius rolls around the Ulna at both the wrist and elbow. So in this position the Radius and Ulna appear crossed.

Muscles of the Radius and Ulna

The muscles that connected to the Ulna and Radius are the Triceps/
