Explanation: The body of veebra T4 aiculates with the heads of the fouh and fifth ribs. The body of the T3 veebra aiculates with the head of the third and fouh ribs. The neck of a rib does not aiculate with any pa of the veebra. The transverse process of the veebra aiculates with the tubercle of the corresponding rib. Therefore, the transverse process of veebra T4 aiculates with the tubercle of the fouh rib.
