Arm movement refers to the ability of the arms to move in various directions, allowing for a wide range of activities. This movement is primarily controlled by muscles, tendons, and joints, particularly the shoulder, elbow, and wrist joints. The shoulder joint enables the arm to rotate and lift, while the elbow allows for bending and straightening. Different types of arm movements include lifting, reaching, pushing, and pulling. These actions are essential for daily tasks such as carrying objects, writing, and playing sports. Proper arm movement is important for maintaining muscle strength and overall physical health.
