Answer: This bone is Ulna part of upper limb.

Explanation:

The longest and thinnest bone in the forearm is the ulna. It moves proximally with the head of the radius and the humeral trochlea. An articular disk separates it from the carpal bones and articulates distally with the ulnar notch of the radius.

Humerus is a long bone in land vertebrates' upper limb or forelimb that connects the shoulder joint above, where it articulates with a lateral depression of the shoulder blade (the glenoid cavity of the scapula), and the elbow joint below, where it articulates with ulna and radius projections.

The humeral head's articular surface is hemispherical in humans; From the scapula, two rounded projections below and to one side receive muscles that rotate the arm. Cross-sectionally, the shaft is triangular and rougher where muscles attach. The lower end of the humerus has two projections (epicondyles), two depressions (fossae) that are part of the elbow joint, and two smooth articular surfaces (capitulum and trochlea).

The radius articulates laterally with the capitulum; The spool-shaped surface of the trochlea articulates with the ulna. As the elbow is alternately flexed and straightened, the ulna projects into the two depressions—the olecranon fossa behind and above the trochlea and the coronoid fossa in front and above. The muscles that are involved in the movements of the forearm and fingers are able to attach to the epicondyles, which are located on either side of the bone.
