The elbow joint is a hinge joint formed by the meeting of the humerus, radius, and ulna. what type of bone marking enables these bones to fit together to form the joint

The correct answer is antecubital fossa.

Explanation:

Elbow joint is formed by three bones -the humerus, ulna, and radius.  

These bones at the meeting point form a small triangular depression like structure in the bone called "antecubital fossa". This fossa is created by the end of the humerus in the anterior surface of the forearm. This contains four main structures: the radial nerve, biceps tendon, brachial artery and median nerve.

Thus, the antecubital fossa is the correct answer.
