The inferior tip of the heart, lying just to the left of the sternum near the fourth and fifth ribs, is called what?

1. The heart is shaped somewhat like a pinecone, broad at the top and tapering toward the bottom. 2. The great veins and arteries attach to its superior surface, called the base. 3. The inferior tip, lying just to the left of the sternum between the fourth and fifth ribs, is called the apex. 4. The cardiac notch is a depression in the lung caused by the apex's leftward deviation, and the auricle is a flap of the atrium, so neither names the heart's inferior tip. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 19 "The Cardiovascular System: The Heart", section 19.1, p. 824_
