Here are the essential concepts you must grasp in order to answer the question correctly.
Sternum Anatomy
The sternum, or breastbone, is a flat bone located in the center of the chest. It consists of three main parts: the manubrium (superior portion), the body (middle portion), and the xiphoid process (inferior portion). Understanding the anatomy of the sternum is crucial for identifying its parts and their functions in the skeletal system.

Articulation
Articulation refers to the connection between bones at a joint. In the context of the sternum, the manubrium articulates with the clavicles (collarbones) and the first rib, forming important joints that allow for movement and stability in the upper body. This concept is essential for understanding how the sternum interacts with surrounding structures.

Rib Cage Structure
The rib cage is a bony structure that protects vital organs in the thoracic cavity, including the heart and lungs. It is composed of the sternum, ribs, and thoracic vertebrae. The relationship between the sternum and the ribs is significant for respiratory mechanics and overall chest stability, making it a key concept in understanding thoracic anatomy.
