Rotator cuff refers to the group of muscles and tendons that connect the upper arm to the scapula or shoulder blade. The tendons of the rotator cuff help in providing stability to the shoulder and the muscles help in rotation of shoulder. There are four types of muscles present in the rotator cuff-teres minor, supraspinatus, subscapularis and infraspinatus. Teres minor muscle helps in outward movement of arm, supraspinatus muscles helps in moving the arm away from body, subscapularis helps in inward movement of arm and infraspinatus muscle help in lifting of arm when the arm is moved outward. If there is tearing of any one of the four muscles then rotator cuff tear. Any damage to the rotator cuff causes rotator cuff disease.
The damage can occur to the rotator cuff due to some inflammation caused by arthritis or tendinitis or because of ageing. The symptoms of rotator cuff disease include shoulder pain which at acute level can cause frozen shoulder. The person having rotator cuff disease finds it difficult to lift the arm. The disease can be diagnosed either by X-ray or radiology testing.
Journal Article is sometimes called a Scientific Article, a Peer-Reviewed Article, or a Scholarly Research Article. Together, journal articles in a particular field are often referred to as The Literature.
Journal articles are most often Primary Research Articles. However, they can also be Review Articles. These types of articles have different aims and requirements. Sometimes, an article describes a new tool or method.
Because articles in scientific journals are specific, meticulously cited and peer-reviewed, journal databases are the best place to look for information on previous research on your species. Without a background in the field, journal articles may be hard to understand - however, you do not need to understand an entire article to be able to get valuable information from it.
