Scapula shoulder blade from "summary" of Human Anatomy by McKinley,O'Loughlin
The scapula, also known as the shoulder blade, is a flat triangular bone located in the upper back. It is a crucial part of the shoulder joint as it helps to support the arm and provides a point of attachment for the muscles of the chest, shoulder and back.- The shoulder blades, or scapulae, are large, flat bones located near the middle of your back. They sit directly above and parallel to each other.
- Scapulae consist of three parts – the spine, the acromion process, and the coracoid process. The spine runs down the middle of the muscle while the other two parts are located on either side and angle outward from the spine.
- The scapulae contain several muscles that work together to move your arms in various directions. For example, the supraspinatus helps raise your arm sideways away from your body, and the infraspinatus aids in lowering this same movement.
- In addition, scapular muscles are essential for stabilizing your entire thoracic region (chest area.. They help keep the shoulder joint stable by providing support through muscular tension.
- Poor posture can cause misalignment of the shoulder blade and contribute to pain and discomfort. To ensure optimal health and flexibility, good posture is key.
- Together with the humerus bone in the upper arm, these muscles form a joint called the shoulder girdle. This structure helps to provide stability and mobility to your shoulders when performing regular activities like reaching and turning.
- Taking care of your physical health is important, and proper rest and exercise help to maintain strong shoulder blades. Shoulders should always be supported when lifting items, and stretching regularly will help prevent injury.
