gingival c.The most coronal portion of the gingiva around the tooth.

rotator c.A musculotendinous structure consisting of supraspinatus, infraspinatus, teres minor, and subscapularis tendons blending with the shoulder joint capsule. The muscles, which surround the glenohumeral joint below the superficial musculature, stabilize and control the head of the humerus in all arm motions, function with the deltoid to abduct the arm, and rotate the humerus. Weakness in the cuff muscles may lead to impingement syndromes and tendinitis; tears in the cuff may lead to subluxations; and calcification may lead to immobilization of the shoulder.

universal c.A device fitted around the palm of the hand to permit attachment of self-care tools when normal grasp is absent.
