How many bones in shoulder bones?

The shoulder, also known as the shoulder joint, is a complex and flexible joint that connects the upper arm bone (humerus) to the torso. It consists of several bones, muscles, tendons, and ligaments that work together to provide a wide range of motion and support.

The bones that form the shoulder include:

- Clavicle (collarbone): The clavicle is a long, slender bone that connects the sternum (breastbone) to the shoulder joint. It helps to support the upper arm and provide stability to the shoulder.

- Scapula (shoulder blade): The scapula is a flat, triangular bone that forms the back of the shoulder. It provides a surface for the attachment of muscles and ligaments that control shoulder movement.

- Humerus (upper arm bone): The humerus is the largest bone in the upper arm. It connects to the scapula at the shoulder joint and to the bones of the forearm at the elbow joint.

- Acromion: The acromion is a bony projection that forms the tip of the shoulder. It is formed by the meeting of the spine of the scapula and the clavicle.

- Coracoid process: The coracoid process is a hook-like projection of the scapula. It serves as an attachment point for several muscles and ligaments that control shoulder movement.

In summary, the shoulder is made up of the clavicle, scapula, humerus, acromion, and coracoid process. These bones, along with the muscles, tendons, and ligaments that surround them, work together to form the shoulder joint and provide us with the ability to move our arms in various directions.
