手肘的英文怎么写_手肘的英文怎么说。

Elbow, a joint that connects the upper arm bone to the forearm bones, is an essential part of the human body. It allows us to bend and straighten our arms, rotate our forearms, and perform a wide range of everyday activities. In this article, we will explore the anatomy of the elbow, its functions, common injuries, and treatments.

The elbow joint is made up of three bones: the humerus, the ulna, and the radius. The humerus is the upper arm bone, while the ulna and radius are the two bones in the forearm. The humerus and ulna form the hinge joint of the elbow, while the radius rotates around the ulna to allow for forearm rotation.

The elbow joint is surrounded by several ligaments and tendons that provide stability and support. The ulnar collateral ligament (UCL) is located on the inside of the elbow and helps to prevent excessive side-to-side movement. The radial collateral ligament (RCL) is located on the outside of the elbow and provides additional support. The biceps tendon attaches the biceps muscle to the radius bone, while the triceps tendon attaches the triceps muscle to the ulna bone.

The elbow joint is responsible for a wide range of movements, including flexion, extension, pronation, and supination. Flexion is when we bend our elbow to bring our hand closer to our shoulder, while extension is when we straighten our arm. Pronation is when we turn our palm down, and supination is when we turn our palm up.
