cardiac notch – melancholy while in the medial surface area on the inferior lobe of the left lung exactly where the apex in the heart is located.
basilic vein – superficial vein from the arm that arises with the palmar venous arches, intersects Together with the median cubital vein, parallels the ulnar vein, and proceeds in the higher arm; along with the brachial vein, it contributes to the axillary vein.
