The evolutionary history of the cuckoo is shrouded in mystery owing to a dearth of fossil evidence. However, experts assert that the Dynamopterus velox, is an ancestor of the species. The bird became known to science owing to the discovery of its right humerus in France. It was larger than...
The upper arm is one long bone, the humerus. The top fits neatly into the scapula, and the lower end is connected by the elbow joint to the two bones of the lower arm: the ulna (the bone on the same side as your little finger) and the radius (the bone on the side of your ...
The bones and muscles of the wing are also highly specialized. The main bone, the humerus, which is similar to the upper arm of a mammal, is hollow instead of solid. It also connects to the bird’s air sac system, which, in turn, connects to its lungs. The powerful flight muscles ...
Bones of the arm and hand: The arm has three basic components: the upper arm, the lower arm and the hand. The upper arm is one long bone, the humerus. The top fits neatly into the scapula, and the lower end is connected by the elbow joint to the two bones of the lower arm: the...

The shoulder is a complex ball-and-socket joint comprising the head of the humerus, the clavicle (collarbone), and the scapula. The shoulder’s main motions are flexion, extension, abduction, adduction, internal rotation, and external rotation. Shoulder flexion is movement of the shoulder in a...
flexor muscle, any of the muscles that decrease the angle between bones on two sides of a joint, as in bending the elbow or knee. Several of the muscles of the hands and feet are named for this function. The flexor carpi radialis and flexor carpi ulnaris stretch from the humerus (upper...
