The correct answer is Right marginal artery. The right marginal artery is a branch of the right coronary artery that runs along the right border of the heart. It supplies blood to the right ventricle and the bottom part of the right atrium.

The left marginal vein is not matched because it is not a major vein in the cardiovascular system. The superior vena cava is a large vein that carries deoxygenated blood from the upper body to the heart. The middle cardiac vein is a vein that runs alongside the middle of the heart and helps drain deoxygenated blood. The coronary sinus is a large vein that collects deoxygenated blood from the heart muscle and returns it to the right atrium of the heart. However, the left marginal vein is not a major vein in the cardiovascular system.

The correct answer is teres minor, teres major. Teres minor and teres major are both muscles located in the shoulder. Teres minor is a small muscle that helps to rotate the arm outward, while teres major is a larger muscle that helps to extend, adduct, and medially rotate the arm. These muscles work together to provide stability and movement to the shoulder joint.

The given answer is 4= axillary vein. This is because the other options are correctly matched with their corresponding anatomical structures. The left common iliac is matched with 16, the inferior vena cava is matched with 5, and the subclavian vein is matched with 10. However, the axillary vein is not matched with any number in the given options.

The correct name of this muscle is Teres minor.

The given options are all structures of the femur bone. The shaft refers to the long, cylindrical portion of the bone. The fovea capitis is a small depression on the head of the femur. The medial epicondyle is a bony prominence on the inner side of the distal end of the femur. The correct answer, linea aspera, is a ridge-like structure on the posterior surface of the femur that serves as an attachment site for muscles and ligaments.

The correct answer is 2 only. This means that only the second number indicates the Costochondral junction. The first number does not indicate the Costochondral junction.

The correct name of this muscle is the internal oblique. The internal oblique is one of the muscles of the abdominal wall and is located beneath the external oblique muscle. It is responsible for various movements of the trunk, including rotation and lateral flexion. The rectus abdominis is a different muscle that runs vertically along the front of the abdomen, while the pectoralis minor is a muscle located in the chest.

The muscle that is medial to the flexor digitorum is the flexor carpi ulnaris. This means that the flexor carpi ulnaris is located closer to the midline of the body compared to the flexor digitorum.
