A pivot joint is a type of synovial joint that allows for rotational movement around a single axis. In relation to the sternum, the pivot joint is exemplified by the atlantoaxial joint between the first and second cervical vertebrae (the atlas and axis), which allows for head rotation. While the sternum itself does not form a pivot joint, the movement of the cervical spine, including the pivot action, can affect the overall posture and alignment of the thoracic region to which the sternum is attached.
The directional term for the sternum to the vertebral column is anterior. This means that the sternum is located in front of or toward the front of the vertebral column in anatomical position.
The vertebral region is located posteriorly (toward the back) in relation to the sternal region, which is situated anteriorly (toward the front) in the thoracic area of the body. The sternal region corresponds to the sternum or breastbone, while the vertebral region refers to the spinal column. Thus, if you visualize the body in an anatomical position, the vertebral region lies behind the sternal region.
The anatomical cavity that contains all of the thoracic viscera except the lungs is the mediastinum. The mediastinum is located between the lungs and extends from the sternum to the vertebral column, and from the thoracic inlet to the diaphragm. It houses vital structures such as the heart, great vessels, trachea, esophagus, and thymus gland.

The epigastric region.

The humerus is lateral to the sternum. The sternum, or breastbone, is midline.
In anatomical position, the hands are indeed inferior to the xiphoid process of the sternum.
The vertebral region is located posteriorly (toward the back) in relation to the sternal region, which is situated anteriorly (toward the front) in the thoracic area of the body. The sternal region corresponds to the sternum or breastbone, while the vertebral region refers to the spinal column. Thus, if you visualize the body in an anatomical position, the vertebral region lies behind the sternal region.
The heart is being mechanically compressed between the sternum and the spinal column. This external mechanical compression is what forces the heart to pump blood. There is not a specific anatomical part of the heart that CPR is performed on.
A Right Anterior Oblique position for the sternum is preferred over a Left Anterior Oblique because it better visualizes the sternum without superimposing anatomical structures. This positioning also minimizes radiation exposure to critical organs such as the heart.
The ribs that don't connect to the sternum are known as floating ribs. There are two pairs of floating ribs, specifically the 11th and 12th pairs of ribs. Unlike true ribs, which attach directly to the sternum, and false ribs, which are indirectly connected, floating ribs are only attached to the vertebrae in the back and do not have any anterior connection. This anatomical feature provides flexibility and protection to the lower back.
superior, in anatomical terms means closer to the top of the body, and inferior means closer to the bottom of the body. eg, your neck is superior to your pelvis. anterior means towards the front of the body, posterior towards the back. eg, your sternum is anterior of your scapular. so, 'is your spine superior to your sternum' is not correct. this actually mixes the terminology of superior/inferior and anterior/posterior. your spine cannot be 'higher' than your sternum, it can however be posterior to your sternum. Hope this helps!
The gallbladder is lateral to the sternum. The sternum is a midline structure.
