Solution
The correct option is D Humerus The correct option is D.
The forelimb comprises of humerus, radius, ulna, carpals, metacarpals, and phalanges.
The humerus is the long bone in the upper arm. It is located between the shoulder and the elbow joint.
The roughly triangular area on the anterolateral (front-side) surface of the middle of the humerus is called as the deltoid ridge. The deltoid muscle is attached to the deltoid ridge. Hence a deltoid ridge occurs in the humerus.
