We just learned about the Esophagus
The bones on the upper part of your shoulder are called the clavicle (or collarbone) and the scapula (or wingbone).
The clavicle is the bone in the front that goes from your neck to your shoulder.
It is connected to your sternum (middle of your chest) and your scapula.
The scapula is the bone in the back that sticks out like a wing, and connects up to the back of your shoulder.
It is connected to your clavicle and your upper arm bone.
