(137).jpg "The Elbow Joint: Functions And Location! Quiz")
How much do you know about the elbow joint, functions, and location? The elbow is a visible joint between the upper and lower parts of the arm. The elbow is a compound joint with a cartilage layer that permits it to move and function correctly. These include the proximal joint, the humeroradial joint, and the humeroulnar joint. This quiz will put the elbow in its place and allow you to learn interesting trivia with every question you attempt. You got this.
