Your scapula is your shoulder blade. The scapula connects the collar bone to the upper arm.
The scapula is the anatomical term for the flat, triangle-shaped bone that makes up a human's shoulder. Other animals have similar bones, often described as scapular. The word scapula means "shoulder" in Late Latin, from the Latin root scapulae, or "shoulder blades." One guess about the word's origin says the original meaning of scapulae was "spades or shovels," based on their similar shapes.
