What is an "elbow"?

An elbow is a pivotal joint connecting the upper arm to the forearm, allowing for essential movements and actions. It functions as a hinge joint, enabling flexion and extension, as well as a pivot joint, facilitating rotation of the forearm. The elbow joint consists of bones, ligaments, tendons, and muscles, working together to provide stability and mobility. It plays a crucial role in activities such as bending the arm, lifting objects, and performing various tasks that require forearm movement. The elbow is an integral part of the upper limb, enabling us to engage in a wide range of everyday activities with precision and control.
