No, the sternum is NOT the same thing as vertebrae. The sternum is the breastbone. Vertebra are in the spine.
: Vertebrae are posterior (or dorsal) to the sternum and medial to the kidneys.
The spine.
spine and sternum
Dorsal is the back , along the spine, i.e., a dorsal fin on a fish, a person laying on their back is said to be in a dorsal recumbant position.
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 ridge on the dorsal surface of the shoulder blade is called the spine.
