The shoulders are the body part between the neck and upper arms. The bones in the shoulder are the clavicle, scapula, and humerus. The muscles attached to these bones are responsible for the movement of the shoulder.

The main muscle groups are the deltoids, rotator cuff muscles, and trapezius. The shoulders provide a large range of motion for the arms. They are the most flexible joints in the human body.

The shoulder joint is held together by ligaments, tendons, and muscles. The rotator cuff muscles and tendons attach the humerus to the scapula. These muscles and tendons keep the head of the humerus in the socket and help lift the arm.

The deltoid muscle is a large muscle that covers the shoulder joint. It attaches the clavicle to the humerus and helps lift the arm. The trapezius muscle attaches the neck and back to the scapula. It helps move the shoulder and hold the shoulders upright.

The shoulder joint is a very important joint in the human body. It allows us to reach, lift, and carry things. We use our shoulders every day.

Without shoulders, we would not be able to do many of the things we take for granted, such as combing our hair, brushing our teeth, or even giving someone a hug.
